Subject: [PATCH 005/146] Claude refactored post-processing drivers Had Claude
 help me with the post-processing driver aspect of things as it also helped
 with all of the trait stuff. No way this stuff probably works right now but
 it at least starts getting us moving in the right direction...

Subject: [PATCH 006/146] Add a new space for expt MFEM impl and also partial
 qfunc/qspace Claude helped me fill out some of the impl details for the
 qspace / qfunc work but largely I had to iterate on its initial design as it
 was making some assumptions that weren't great

Subject: [PATCH 007/146] Initial implementation of the simulation state class
 Had to add a time management class to keep all the logic related to that in
 just one class Updated the partial quadrature space just a bit for the case
 when the incoming index is empty to signal all values are provided Initial
 complete implementation of the simulation class. I also added a bunch of
 other stuff here from the initial prototype of it based on common things that
 we'd generally across all of the simulation stuff.

Subject: [PATCH 008/146] WIP - working on a new set of option parser
 co-developed by claude Iterated with Claude a bit on a potentially new option
 parser for ExaConstit which will hopefully be more flexible for
 multi-material systems. Additionally, I've started to revamp things a bit so
 that at least all of the files outside of the mesh should be read ahead of
 time so we can avoid more of MFEM's file load options as they generally
 aren't the best. I'm still not the most satisified with how things are broken
 up for everything, but I do believe it's moving in the right direction.

Subject: [PATCH 010/146] Update option parser refactor to include more
 validation and other features and update SimState while at it Added quite a
 bit more validation aspects to the refactored options parser. Although, I
 still need to test this and also create better logging features. Updated a
 number of the options structs based on some of the original info not making
 sense or just needing to make somethings optional and such. Started to update
 the SimulationState class to make work with this newly refactored ExaOptions
 class. Additionally, I added in the necessary logic to handle the
 grains2region mapping even if the grains2region mapping was not provided by
 users. Things are still very much a work in progress though but the current
 state is getting us much closer to where we want to be in-order to handle
 multi-material systems.

Subject: [PATCH 011/146] WIP slowly moving over to new options and sim_state
 headers (doesn't build yet) Starting to incrementally move everything over to
 these new header files. I'm still fixing compiler issues in the
 simulation_state.* files. So, it's coming along but I still have more to go.
 Outside of that, I've got a ton of stuff now compiling and fixed quite a few
 bugs with the new classes being added. So, everything up to the
 SimulationState in terms of the compilation stage of things now at least
 compiles. Although, I threw my hands up in the air for some of the features
 that no longer exist in the option file such as if the vgrad_origin is being
 used or if we're using the experimental mono_dirichlet BCs... I'll work
 through all of that later but hey it's a start.

From ea94b5047f36a6f72ec586d5658a8bcabaf7ff40 Mon Sep 17 00:00:00 2001
From: Robert Carson <carson16@llnl.gov>
Date: Mon, 19 May 2025 19:44:58 -0700
Subject: [PATCH 012/146] More bug fixes to get things compiling The
 SimulationState class now compiles after fixing numerous issues. Also made
 some changes to the ExaOptions class and related sub-classes to make things a
 bit more sensible.

Subject: [PATCH 013/146] WIP start updating mechanics_driver source to get to
 compile Fixed a ton of the compile errors but still got to do all of the time
 step management type stuff Pushing off the post-processing stuff for a bit
 longer as it's currently not critical to get done...

Subject: [PATCH 014/146] WIP refactor now compiles but seg-faults... New
 changes all now compile and we can now at least get something produced but
 things crash hard when we try to run things :/ So, we get to debug things a
 bit more to see if we can get things working in the new code paths.

Subject: [PATCH 016/146] Claude generated PrintOptions version of things +
 small changes Went ahead and had Claude generate outputs of all of the
 simulation file options that we are using and to try and make it somewhat
 similar to what was in the original version of things. Next, a few small bug
 fixes related to the options were also brought in here to get the simulations
 to actually run

Subject: [PATCH 017/146] Finally got the simulations working :) The voce_full
 / ea / pa runs are now running and returning answers that are identical to
 the original v0.8.2 release of the code. Although, it should be noted that I
 still need to work through some more options issues with the averaging issues
 not working quite as expected. However, we're doing pretty good so far. This
 included quite a few small bug fixes to get this working

Subject: [PATCH 019/146] Fix more bugs: vgrad and auto time now work Fixed
 issues related to the vgrad BCs and also the automatic time stepping BCs
 Fixed an issue if the auto time stepping was present in the option file but
 the custom one was also provided Updated some of the driver print options so
 that it always tells us what cycle we were on and the various time info aka
 the current time, prev dt, new dt, and factor things changed by for
 everything

Subject: [PATCH 022/146] Move more stuff over to using the SimulationState
 class and some bug fixes We now leverage the simulation state class for all
 of our primal and mesh related quantities of interest rather than passing
 things down the call stack / having classes that have no business controlling
 things moving the mesh around... Fixed a few bugs in the process for the
 TimeManagement related to when we only have 1 time step. Fixed an issue with
 how the SimulationState was assuming the Update step should occur after we've
 completed a step which led to some differences in our results with the legacy
 code. Fixed an issue with how our mesh nodes were being connected with the
 current nodal values as some of MFEM's funcs operated internally differently
 than I expected them to... Currently the basic UMAT related tests are turned
 off as they're broken... I'll have to work something out though for those.

Subject: [PATCH 024/146] Add next set of hooks for multi-material support
 Added a new "super" model class which runs all of the material model aspects
 of things. Theoretically, this should now be able to run multi-materials but
 have not tested it at all...

+ * 2. Route global simulation data to appropriate child models
+ * 3. Coordinate child model execution during setup phases
+ * 4. Aggregate results from child models into global data structures
+ * 5. Present a unified ExaModel interface to external code
+ * 
+ * This design eliminates the need for external classes (like NonlinearMechOperator)
+ * to understand or manage multiple models, significantly simplifying the overall

Subject: [PATCH 025/146] Add additional logic to help with the local element
 logic for multi-materials For ECMech and UMat models made sure the model
 setup aspect of things Additionally added some helper functions to the
 partialQuadSpace to make things a bit easier to work with Had to update some
 of the kernel logic also to make things a bit simpler Also Claude helped with
 some of this refactoring

Subject: [PATCH 026/146] Multi-material state variable init fix Thanks to
 Claude I didn't have to completely rewrite the state variable initialization
 aspect of things. So, it does appear that the multi-material stuff is now
 working :) I need to still do some reworking of some stuff and add a new test
 related to the multi-material stuff but hey things are looking good now.

Subject: [PATCH 027/146] Refactor state_var_init so ori calcs are in own
 function and a few other small changes Used Claude to help refactor the state
 variable initialization aspect so that the orientation stuff is all handled
 in different functions. It generated most things which appear to be working.
 However, it also attempted to generate conversion funcs for going from unit
 quats to bunge euler angles or rotation matrices. However, I did not like
 it's approach so I replaced it them with implementation that I know are
 numerically stable and work as I would expect. Outside of that removed the
 numStateVar input condition in the SystemOperator class and
 NonlinearMechanicalOperator (NLMO) class. Also removed the mech_type variable
 in the NLMO class.

Subject: [PATCH 029/146] Claude refactor for postprocessing class for
 multi-materials Claude helped refactor the post-processing class for me. It's
 not perfect but it now reliably prints out the average stress values for
 everything and can do it for multi-materials. I just need to extend it now to
 all of the other additional variables that we were working with before and
 have special logic in there for all the others as they did their own things.
 I also need to revive all of the logic related to projecting various
 variables to our DataCollections...

Subject: [PATCH 030/146] Claude-generated (largely) legacy option file to new
 option file format script Had Claude more or less generate new option files
 from the old legacy option files. It struggled quite a bit to try and get it
 working especially with the formatting. However, I ended up having to give up
 on that aspect of getting it to work and just worked with ChatGPT to help
 with the formatting... It did have some good suggestions for how to go about
 that. Overall, all of them wanted to over complicate things and add things
 that didn't exist at all in either the legacy or new formats and took quite a
 bit of time to get it to just do what it needed to...

+"""
+Migration script for ExaConstit option files from old format to new format.
+Converts old option_parser.cpp/hpp TOML format to option_parser_v2.cpp/hpp format.
+
+Key features:
+- Handles case-insensitive option values from old parser
+- Normalizes solver names (e.g., PCG -> CG)
+- Converts various spelling variations to canonical v2 format
+- Normalizes boolean values (true/True/TRUE/yes/1 -> true)
+- Preserves backward compatibility while enforcing v2 conventions
+
+The script automatically handles common variations in:
+- Solver types (PCG->CG, various cases)
+- Assembly modes (pa/PA, full/FULL, etc.)
+- Material models (ExaCMech/exacmech/EXACMECH)
+- Crystal types (fcc/FCC/Fcc)
+- Boolean values (true/True/yes/1/on)
+- And many more...

Subject: [PATCH 031/146] Make the option parser more compatible with legacy
 format The new option parser should now be more or less completely compatible
 with the legacy format. I still need to hook up various aspects of the code
 to verify this but that's what it appears to be the case. I still need to
 address the post-processing aspect so all of the legacy def_grad,
 eq_pl_strain, pl_work, and euler strain. Then afterwards I need to get the
 actual visualization aspect of things working. Also fixed a small bug with
 the post-processing in the time steps for printing where it was one time step
 ahead. Also set things up so that if a basename is not provided in the
 options file then the base name of the option file is used as the basename
 which is leveraged in the output folder creation.

Subject: [PATCH 033/146] Add back in support for volume average def grad and
 euler strain calcs... Re-enabled the def grad and euler strain calcs with
 minimal additions and by bringing back a few small calculations here and
 there so not really too many extra calcs. Might need to move some things in
 the operator class over to the sim_state version just to unify everything...

Subject: [PATCH 034/146] Re-enable capability to output all additional vol
 average calcs Re-added all of the additional volume average / integration
 values we used to have. Next, it just needs to be made more efficient as well
 in that we need to cache values between calculations. Next steps are to look
 at the visualization stuff and make sure we can have that brought back and
 then the lightup stuff...

Subject: [PATCH 036/146] Initial commit to re-add visualizations back to
 simulations Moved away from the complicated projection form for doing all of
 the visualization stuff. It is now much simpler and appears to be working.
 So, we can now start removing a lot of stuff that is no longer needed :)

Subject: [PATCH 041/146] Update post-processing to use ParSubMeshes for region
 data Didn't like how the region data required us to filter out data which
 made it difficult to plot things together. So moved over to ParSubMesh for
 all of the region data and also the Global data isn't plotted if there is
 only 1 region. More improvements need to be made but appears to be made in
 the right way.

Subject: [PATCH 046/146] Part 4 of cleaning up various portions of code
 (simplify ExaModel class) This commit greatly simplifies the ExaModel by
 moving all of the strain calculations to free functions in utility headers.
 Also, all of the rotation stuff was also moved to rotation headers. I also
 removed all of the FEM related funcs to their own headers as well. This
 allowed me to remove the need to have the model passed into the integrator
 class as well. Overall this greatly simplified most things quite a bit

From bfa4d9981fca80c734874cacd7d0ef9b8801e337 Mon Sep 17 00:00:00 2001
From: rcarson3 <robert.carson01@gmail.com>
Date: Mon, 7 Jul 2025 18:09:48 -0700
Subject: [PATCH 050/146] Fixed light up option so it can now support
 multi-materials (still assumes everything is cubic for now...) Claude helped
 address the issue of the light-up not supporting multi-materials by adding
 support for it in the Options parser. I then re-enabled it on the
 post-processing side by removing it from the systems driver and moving it to
 the post-processing driver. I had to add a new vol avg filter kernel to work
 with partial quadrature functions. Overall it appears to be working though...

Subject: [PATCH 051/146] Add a way to dynamically load UMAT libraries / funcs
 Claude driven but this should hopefully allow us to dynamically load up the
 UMATs at runtime and allow us to have multiple UMATs going at the same time.
 However, I have not tested it yet but will potentially get to that in the
 near term.

-/// Abaqus Umat class.
-/// 
-/// KEY ARCHITECTURAL CHANGE: This class no longer takes QuadratureFunction pointers
-/// in its constructor. Instead, it receives a region identifier and accesses all
-/// QuadratureFunctions through the SimulationState interface. This enables:
-/// 1. Better encapsulation - the model doesn't manage QF lifetimes
-/// 2. Multi-material support - each model instance knows its region  
-/// 3. Dynamic access - models can access different QFs based on runtime conditions
-/// 4. Simplified construction - much fewer constructor parameters
+/**
+ * @brief Enhanced Abaqus UMAT model with dynamic library loading support
+ * 
+ * This enhanced version supports loading UMAT implementations from shared libraries
+ * at runtime, eliminating the need to recompile ExaConstit for new UMATs.
+ * 
+ * Key features:
+ * - Dynamic loading of UMAT shared libraries
+ * - Support for multiple UMATs in different regions
+ * - Configurable loading strategies (persistent, on-demand, etc.)
+ * - Thread-safe library management
+ * - Automatic cleanup and error handling

+ * The optimal step size is: ε = -b/(2a) = (3*q1 - 4*q2 + q3) / (4*(q1 - 2*q2 + q3))
+ * 
+ * **Robustness Checks**:
+ * - Validates quadratic fit: (q1 - 2*q2 + q3) > 0 (convex)
+ * - Bounds step size: 0 < ε < 1 (reasonable range)
+ * - Fallback logic when quadratic fit fails
+ * 
+ * **Performance Profiling**:
+ * - "NRLS_solver" scope for overall line search Newton performance
+ * - "Line Search" scope specifically for step size computation
+ * - "krylov_solver" scope for linear solver calls
+ * 
+ * **Memory Management**:
+ * - Uses device-compatible temporary vectors (x_prev, Jr)
+ * - Efficient vector operations with MFEM's device interface
+ * 
+ * **Failure Handling**:
+ * - Scale factor of 0.0 triggers immediate convergence failure
+ * - Graceful degradation when line search produces invalid results

+ * while maintaining compatibility with MFEM's finite element framework.
+ * 
+ * Key features:
+ * - Efficient memory usage by storing data only for active elements
+ * - Optimized performance through local-to-global index mapping
+ * - Full compatibility with MFEM's QuadratureSpaceBase interface
+ * - Support for both partial and full mesh coverage with automatic optimization

+ * - Maximum 500 iterations with configurable tolerance
+ * 
+ * The algorithm performs these steps:
+ * 1. Extract initial rotation estimate using SVD-based quaternion method
+ * 2. Iteratively refine rotation using exponential mapping
+ * 3. Compute axial vector corrections for rotation updates
+ * 4. Apply exponential mapping to update rotation matrix
+ * 5. Converge when correction magnitude falls below tolerance
+ * 6. Compute stretch tensors: U = R^T * F, V = F * R^T
+ * 
+ * Applications in solid mechanics:
+ * - Large deformation analysis requiring objective stress measures
+ * - Crystal plasticity with finite rotations
+ * - Hyperelastic material models using stretch-based formulations
+ * - Kinematic analysis of deforming structures
+ * 
+ * Reference: "A Robust Method to Extract the Rotational Part of Deformations"
+ * by Müller et al., MIG 2016
+ * 
+ * @note The input matrix R is modified in place and becomes the rotation output.
+ * @note The algorithm assumes the input represents a valid deformation gradient (det(F) > 0).
+ * @note Convergence is typically achieved in 5-15 iterations for typical FE problems.
+ * @note The method is more stable than traditional SVD-based approaches for ill-conditioned cases.
+ * 
+ * Usage example:
+ * @code
+ * mfem::DenseMatrix F(3), R(3), U(3), V(3);
+ * // ... populate F with deformation gradient ...
+ * R = F; // Copy F since it will be modified
+ * CalcPolarDecompDefGrad(R, U, V);
+ * // Now R contains rotation, U and V contain right and left stretch

+ * 
+ * The LightUp class performs in-situ lattice strain calculations that simulate
+ * powder diffraction experiments on polycrystalline materials. It computes
+ * lattice strains for specified crystallographic directions (HKL) based on
+ * crystal orientation evolution and stress state from ExaCMech simulations.
+ * 
+ * Key capabilities:
+ * - Lattice strain calculation for multiple HKL directions
+ * - Taylor factor and plastic strain rate analysis
+ * - Directional stiffness computation
+ * - Volume-weighted averaging over grains/orientations
+ * - Real-time output for experimental comparison
+ * 
+ * The class interfaces with ExaCMech state variables including:
+ * - Crystal orientations (quaternions)
+ * - Elastic strain tensors
+ * - Relative volume changes
+ * - Plastic strain rates and slip system activities
+ * 
+ * Applications:
+ * - Validation against in-situ diffraction experiments
+ * - Prediction of lattice strain evolution during deformation
+ * - Analysis of load partitioning between crystallographic directions
+ * - Study of texture effects on mechanical response

-/// A NonlinearForm Integrator specifically built around the ExaModel class

+/**
+ * @brief B-bar method integrator for incompressible and nearly incompressible solid mechanics.
+ * 
+ * ICExaNLFIntegrator extends ExaNLFIntegrator to implement the B-bar method for handling
+ * incompressible and nearly incompressible materials. This integrator is essential for
+ * crystal plasticity simulations where volume preservation constraints arise from
+ * incompressible plastic deformation or nearly incompressible elastic behavior.
+ * 
+ * The B-bar method (Hughes, 1980):
+ * - Modifies the strain-displacement B-matrix to avoid volumetric locking
+ * - Uses volume-averaged dilatational strains to improve element performance
+ * - Maintains accuracy for incompressible and nearly incompressible materials
+ * - Enables stable finite element solutions for high bulk modulus problems
+ * 
+ * Mathematical foundation:
+ * The B-bar method splits the strain into volumetric and deviatoric parts:
+ * ε = ε_vol + ε_dev, where ε_vol is volume-averaged over the element
+ * 
+ * This approach prevents spurious pressure oscillations and volumetric locking
+ * that can occur with standard displacement-based finite elements when dealing
+ * with incompressible or nearly incompressible material behavior.
+ * 
+ * Applications in crystal plasticity:
+ * - Incompressible plastic deformation in crystal slip
+ * - Nearly incompressible elastic response in metals
+ * - Volume-preserving deformation in single crystal simulations
+ * - Polycrystalline materials with incompressible phases
+ * 
+ * Key features:
+ * - Inherits all standard solid mechanics capabilities from ExaNLFIntegrator
+ * - Modifies B-matrix construction for volumetric strain averaging
+ * - Maintains compatibility with all assembly strategies (PA, EA, standard)
+ * - Provides stable solutions for high bulk modulus materials
+ * - Supports large deformation kinematics with volume preservation
+ * 
+ * Implementation details:
+ * - Computes element-averaged volumetric strain gradients
+ * - Modifies standard B-matrix with B-bar corrections
+ * - Uses Hughes' formulation from "The Finite Element Method" Section 4.5.2
+ * - Maintains computational efficiency comparable to standard elements

+       * Template implementation of element assembly operator application using

+       * The element assembly algorithm:
+       * 1. Applies essential boundary conditions to input (if !local_action)
+       * 2. Maps input to element-local DOF ordering via restriction
+       * 3. Performs element matrix-vector products for all elements
+       * 4. Assembles results to global DOF space via restriction transpose

+       * Element matrix-vector product:

+       * - Vectorized implementation over all elements

-// # Description:
-// The purpose of this code app is to determine bulk constitutive properties of metals.
-// This is a nonlinear quasi-static, implicit solid mechanics code built on the MFEM library based
-// on an updated Lagrangian formulation (velocity based). Currently, only Dirichlet boundary conditions
-// (homogeneous and inhomogeneous by dof component) have been implemented. Neumann (traction) boundary
-// conditions and a body force are not implemented. A new ExaModel class allows one to implement
-// arbitrary constitutive models. The code currently successfully allows for various UMATs to be
-// interfaced within the code framework. Development work is currently focused on allowing for the
-// mechanical models to run on GPGPUs. The code supports either constant time steps or user supplied
-// delta time steps. Boundary conditions are supplied for the velocity field applied on a surface.
-// It supports a number of different preconditioned Krylov iterative solvers (PCG, GMRES, MINRES)
-// for either symmetric or nonsymmetric positive-definite systems.
-//
-// ## Remark:
-// See the included options.toml to see all of the various different options that are allowable in this
-// code and their default values. A TOML parser has been included within this directory, since it has
-// an MIT license. The repository for it can be found at: https://github.com/skystrife/cpptoml . Example
-// UMATs maybe obtained from https://web.njit.edu/~sac3/Software.html . We have not included them due to
-// a question of licensing. The ones that have been run and are known to work are the linear elasticity
-// model and the neo-Hookean material. Although, we might be able to provide an example interface so
-// users can base their interface/build scripts off of what's known to work.
-// Note: the grain.txt, props.txt and state.txt files are expected inputs for CP problems,
-// specifically ones that use the Abaqus UMAT interface class under the ExaModel.
-//
-// # Installing Notes:
-// * git clone the LLNL BLT library into cmake directory. It can be obtained at https://github.com/LLNL/blt.git
-// * MFEM will need to be built with Conduit (built with HDF5). The easiest way to install Conduit
-// is to use spack install instruction provided by Conduit.
-// * ExaCMech is required for ExaConstit to be built and can be obtained at https://github.com/LLNL/ExaCMech.git.
-// * Create a build directory and cd into there
-// * Run ```cmake .. -DENABLE_MPI=ON -DENABLE_FORTRAN=ON -DMFEM_DIR{mfem's installed cmake location}
-// -DBLT_SOURCE_DIR=${BLT cloned location} -DECMECH_DIR=${ExaCMech installed cmake location}
-// -DRAJA_DIR={RAJA installed location} -DSNLS_DIR={SNLS location in ExaCMech}
-// -DMETIS_DIR={Metis used in mfem location} -DHYPRE_DIR={HYPRE install location}
-// -DCONDUIT_DIR={Conduit install location} -DHDF5_ROOT:PATH={HDF5 install location}```
-// * Run ```make -j 4```
-//
-// #  Future Implemenations Notes:
-// * Visco-plasticity constitutive model
-// * GPGPU material models
-// * A more in-depth README that better covers the different options available.
-// * debug ability to read different mesh formats
-// * An up-to-date example options.toml file

+ * 
+ * SystemDriver orchestrates the entire nonlinear mechanics simulation workflow for ExaConstit,
+ * implementing a velocity-based, updated Lagrangian finite element framework for solid mechanics
+ * problems with emphasis on crystal plasticity and micromechanics modeling. The class manages
+ * the Newton-Raphson solution process, boundary condition enforcement, and model state updates
+ * throughout the simulation.
+ * 
+ * The driver integrates multiple components:
+ * - Newton-Raphson nonlinear solver with optional line search
+ * - Krylov iterative linear solvers (GMRES, CG, MINRES) with preconditioning
+ * - Essential boundary condition management (velocity and velocity gradient BCs)
+ * - Constitutive model integration and state variable updates
+ * - Device-aware execution supporting CPU, OpenMP, and GPU backends
+ * 
+ * Key simulation capabilities:
+ * - Multi-material nonlinear solid mechanics with large deformations
+ * - Crystal plasticity simulations with grain-specific material behavior
+ * - Complex loading conditions including velocity gradient boundary conditions
+ * - Automated time stepping with adaptive control
+ * - Parallel MPI execution with domain decomposition
+ * 
+ * The class follows the MFEM finite element framework conventions while extending
+ * functionality for ExaConstit's specialized micromechanics applications. It serves
+ * as the central coordination point between mesh management, material models,
+ * solvers, and postprocessing systems.

+### **UMAT Development Best Practices**
+
+#### **Memory Management**
+- **ExaConstit handles**: State variable allocation and persistence
+- **UMAT responsible**: Local variable management within subroutine
+- **No dynamic allocation**: Avoid malloc/new within UMAT calls
+
+#### **Thread Safety**
+- **No global variables**: UMATs must be thread-safe
+- **Local computations**: All calculations using passed parameters
+- **State persistence**: Only through provided state variable arrays
+
+#### **Error Handling**
+- **Convergence issues**: Set appropriate flags for Newton-Raphson
+- **Material failure**: Handle through state variables or stress reduction
+- **Numerical stability**: Check for divide-by-zero and overflow conditions
+
+#### **Performance Considerations**
+- **CPU execution only**: No current GPU acceleration for UMATs
+- **Vectorization**: Ensure compiler optimization is possible
+- **Minimal function calls**: Reduce computational overhead within UMAT
+
+### **Development Resources**
+
+#### **Reference Implementations**

-Version 0.8.0
+**High-Performance Crystal Plasticity & Micromechanics Simulation**
 
-# Description: 
-A principal purpose of this code app is to probe the deformation response of polycrystalline materials; for example, in homogenization to obtain bulk constitutive properties of metals. This is a nonlinear quasi-static, implicit solid mechanics code built on the MFEM library based on an updated Lagrangian formulation (velocity based).
-               
-Currently, only Dirichlet boundary conditions (homogeneous and inhomogeneous by degree-of-freedom component) have been implemented. Neumann (traction) boundary conditions and a body force are not implemented. These Dirichlet boundary conditions can applied per surface/boundary using either the use of applied velocity or applied velocity gradients (constant strain) boundary conditions. One can also mix and match the use of those two boundary condition types across the various boundaries of the problem in order to more complicated material deformations such as pure torsion. Additionally, we support changing boundary conditions. So, it's possible to run cyclic, strain-rate jump tests, or a number of other type simulations.
+*Velocity-based finite element framework for polycrystalline materials*
 
-On the material modelling front of things, ExaConstit can easily handle various material models. We provide a base class, `ExaModel`, to build each material model or class of material models. We currently support  two very different material model libraries/interfaces through UMATs or ExaCMech. Crystal plasticity model capabilities are primarily provided through the ExaCMech library.
+[Quick Start](#quick-start) • [Documentation](#documentation) • [Examples](#examples) • [Contributing](#contributing)
 
-Through the ExaCMech library, we are able to offer a range of crystal plasticity models that can run on the GPU. The current models that are available are a power law slip kinetic model with both nonlinear and linear variations of a voce hardening law for BCC and FCC materials, and a single Kocks-Mecking dislocation density hardening model with balanced thermally activated slip kinetics with phonon drag effects for BCC, FCC, and HCP materials. Any future model types to the current list are a simple addition within ExaConstit, but they will need to be implemented within ExaCMech. Given the templated structure of ExaCMech, some additions would be comparatively straightforward. 
+</div>
 
-The code is capable of running on the GPU by making use of either a partial assembly formulation (no global matrix formed) or element assembly (only element assembly formed) of our typical FEM code. These methods currently only implement a simple matrix-free jacobi preconditioner. The MFEM team is currently working on other matrix-free preconditioners. Additionally, ExaConstit can be built to run with either CUDA or HIP-support in-order to run on most GPU-capable machines out there.
+---
 
-The code supports constant time steps, user-supplied variable time steps, or automatically calculated time steps. Boundary conditions are supplied for the velocity field on a surface. The code supports a number of different preconditioned Krylov iterative solvers (PCG, GMRES, MINRES) for either symmetric or nonsymmetric positive-definite systems. We also support either a newton raphson or newton raphson with a line search for the nonlinear solve. We might eventually look into supporting a nonlinear solver such as L-BFGS as well.
+## What is ExaConstit?
 
-Finally, we support being able to make use of full integration or BBar type integration schemes to be used with various models. The default feature is to perform full integration of the element at the quadrature point. The BBar integration performs full integration of the deviatoric response with an element average integration for the volume response. The BBar method is based on the work given in [this paper](https://doi.org/10.1002/nme.1620150914) and more specifically we make use of Eq 23. It should be noted that currently we don't support a partial assembly formulation for the BBar integrations.
+ExaConstit is a cutting-edge, **velocity-based finite element code** designed for high-fidelity simulation of polycrystalline materials. Built on LLNL's MFEM library, it delivers unprecedented performance for crystal plasticity and micromechanics modeling on leadership-class HPC systems.
 
+### Key Applications
+- **Crystal Plasticity Simulations** - Grain-level deformation analysis
+- **Bulk Constitutive Properties** - Homogenization of polycrystalline materials  
+- **Materials Discovery** - Parameter optimization for new alloys
+- **Additive Manufacturing** - Process-structure-property relationships
+- **Experimental Validation** - Lattice strain calculations for diffraction experiments
 
-## Remark:
-This code is still very much actively being developed. It should be expected that breaking changes can and will occur. So, we make no guarantees about stability at this point in time. Any available release should be considered stable but may be lacking several features of interest that are found in the ```exaconstit-dev``` branch.
+## Features
 
-Currently, the code has been tested using monotonic and cyclic loading with either an auto-generated mesh that has been instantiated with grain data from some voxel data set or meshes formed from ```MFEM v1.0```. Meshes produced from Neper can also be used but do require some additional post-processing. See the ```Script``` section for ways to accomplishing this.
+### **Advanced Finite Element Framework**
+- **Velocity-Based Formulation** - Updated Lagrangian with superior convergence
+- **Large Deformation Analysis** - Geometrically nonlinear solid mechanics
+- **Multi-Material Support** - Heterogeneous material regions
+- **Adaptive Time Stepping** - Automatic timestep control for robustness
 
-ExaCMech models are capable of running on the GPU. However, we currently have no plans for doing the same for UMAT-based kernels. The ExaCMech material class can be used as a guide for how to do the necessary set-up, material kernel, and post-processing step if a user would like to expand the UMAT features and submit a pull request to add the capabilities into ExaConstit.
+### **Crystal Plasticity Modeling**
+- **ExaCMech Integration** - Advanced crystal plasticity constitutive models
+- **Multi-Crystal Support** - BCC, FCC, and HCP crystal structures  
+- **Grain-Level Resolution** - Individual grain orientations and properties
+- **State Variable Evolution** - Full history-dependent material behavior
 
-See the included ```options.toml``` to see all of the various different options that are allowable in this code and their default values.
+### **High-Performance Computing**
+- **GPU Acceleration** - CUDA and HIP support for maximum performance
+- **MPI Parallelization** - Scales to thousands of processors
+- **Memory Efficiency** - Matrix-free partial assembly algorithms
+- **Performance Portability** - RAJA framework for unified CPU/GPU code
 
-A TOML parser has been included within this directory, since it has an MIT license. The repository for it can be found at: https://github.com/ToruNiina/toml11/.
+### **Material Model Flexibility**
+- **ExaCMech Library** - State-of-the-art crystal plasticity models
+- **UMAT Interface** - Abaqus-compatible user material subroutines
+- **Custom Models** - Extensible architecture for new constitutive laws
+- **Multi-Model Regions** - Different materials in different regions
 
-Example UMATs maybe obtained from https://web.njit.edu/~sac3/Software.html . We have not included them due to a question of licensing. The ones that have been run and are known to work are the linear elasticity model and the neo-Hookean material. The ```umat_tests``` subdirectory in the ```src``` directory can be used as a guide for how to convert your own UMATs over to one with which ExaConstit can interface.
+### **Advanced Post-Processing**
+- **Visualization Output** - VisIt, ParaView, and ADIOS2 support
+- **Volume Averaging** - Macroscopic stress-strain behavior
+- **Lattice Strain Analysis** - In-situ diffraction experiment simulation
+- **Python Tools** - Comprehensive analysis and plotting scripts
 
-Note: the grain.txt, props.txt and state.txt files are expected inputs for crystal-plasticity problems. If a mesh is provided it should be in the MFEM or cubit format which has the grains IDs already assigned to the element attributes.
+## Quick Start
 
-# Scripts
-Useful scripts are provided within the ```scripts``` directory. The ```mesh_generator``` executable when generated can create an ```MFEM v1.0``` mesh for auto-generated mesh when provided a grain ID file. It is also capable of taking in a ```vtk``` mesh file that MFEM is capable of reading, and then it will generate the appropriate ```MFEM v1.0``` file format with the boundary element attributes being generated in the same way ExaConstit expects them. The ```vtk``` mesh currently needs to be a rectilinear mesh in order to work. All of the options for ```mesh_generator``` can be viewed by running ```./mesh_generator --help```
+### Prerequisites
+```bash
+# Essential dependencies
+MPI implementation (OpenMPI, MPICH, Intel MPI)
+MFEM (v4.7+) with parallel/GPU support
+ExaCMech crystal plasticity library
+RAJA (≥2022.10.x) performance portability
+CMake (3.12+)
+```
 
-If you have version 4 of ```Neper``` then you can make use of the `-faset 'faces'` option while meshing and output things as a `gmsh` v2.2 file. Afterwards, you can make use of the `neper_v4_mesh.py` cli script in `scripts/meshing` to automatically use the faset information and autogenerate the boundary attributes that `MFEM\ExaConstit` can understand and use. Although, you will need to check and see which face corresponds to what boundary attribute, so you can correctly apply boundary conditions to the body. Further information is provided in the top level comment of the script for how to do this.
+### Installation
 
-For older versions of neper v2-v3, an additional python script is provided called ```fepx2mfem_mesh.py``` that provides a method to convert from a mesh generated using Neper v3.5.2 in the FEpX format into the ```vtk``` format that can now be converted over to the ```MFEM v1.0``` format using the ```mesh_generator``` script.
+#### **Linux/Unix Systems**
+```bash
+# Use our convenient install script
+./scripts/install/unix_install_example.sh
+```
 
-# Examples
+#### **GPU-Accelerated Build (CUDA)**
+```bash
+# NVIDIA GPU systems
+./scripts/install/unix_gpu_cuda_install_example.sh
+```
 
-Several small examples that you can run are found in the ```test/data``` directory. These examples cover a wide range of different use cases of the code, but the `toml` file for each test case may not be representative of all the options as found in the `src/options.toml` file.
+#### **GPU-Accelerated Build (HIP/AMD)**  
+```bash
+# AMD GPU systems
+./scripts/install/unix_gpu_hip_install_example.sh
+```
 
-# Postprocessing
+#### **Manual Build**
+```bash
+# Clone and prepare
+git clone https://github.com/LLNL/blt.git cmake/blt
+mkdir build && cd build
+
+# Configure
+cmake .. \
+  -DENABLE_MPI=ON \
+  -DMFEM_DIR=${MFEM_INSTALL_DIR} \
+  -DECMECH_DIR=${EXACMECH_INSTALL_DIR} \
+  -DRAJA_DIR=${RAJA_INSTALL_DIR}
+
+# Build
+make -j $(nproc)
+```
 
-The ```scripts/postprocessing``` directory contains several useful post-processing tools. The ```macro_stress_strain_plot.py``` file can be used to generate macroscopic stress strain plots. An example script ```adios2_example.py``` is provided as example for how to make use of the ```ADIOS2``` post-processing files if ```MFEM``` was compiled with ```ADIOS2``` support. It's highly recommended to install ```MFEM``` with this library if you plan to be doing a lot of post-processing of data in python.
+### First Simulation
+```bash
+# Run a crystal plasticity example
+cd test/data
+mpirun -np 4 ../../build/mechanics -opt voce_full.toml
 
-A set of scripts to perform lattice strain calculations similar to those found in powder diffraction type experiments can be found in the ```scripts/postprocessing``` directory. The appropriate python scripts are: `adios2_extraction.py`, `strain_Xtal_to_Sample.py`, and `calc_lattice_strain.py`. In order to use these scripts, one needs to run with the `light_up=true` option set in the `Visualization` table of your simulation option file. Alternatively, if you just use the `light_up` option and provide the necessary parameters as defined in the `src/options.toml` file you a set of insitu lattice strain calculations will be done. The cost of these insitu calculations is fairly nominal and are generally advisable to use when performing large scale simulations where this data is desireable.
+# Generate stress-strain plots
+python ../../scripts/postprocessing/macro_stress_strain_plot.py
+```
 
-# Workflow Examples
+## Examples
 
-We've provided several different useful workflows in the `workflows` directory. One is an optimization set of scripts that makes use of a genetic algorithm to optimize material parameters based on experimental results. Internally, it makes use of either a simple workflow manager for something like a workstation or it can leverage the python bindings to the Flux job queue manager created initially by LLNL to run on large HPC systems.
+### **Crystal Plasticity Simulation**
+```toml
+# options.toml - Crystal plasticity configuration
+[Mesh]
+filename = "polycrystal.mesh"
+grain_file = "grain.txt"
+orientation_file = "orientations.txt"
 
-The other workflow is based on a UQ workflow for metal additive manufacturing that was developed as part of the ExaAM project. You can view the open short workshop paper for an overview of the ExaAM project's workflow and the results https://doi.org/10.1145/3624062.3624103 . This workflow connects microstructures provided by an outside code such as LLNL's ExaCA code (https://github.com/LLNL/ExaCA) or other sources such as nf-HEDM methods to local properties to be used by a part scale application code. The goal here is to utilize ExaConstit to run a ton of simulations rather than experiments in order to obtain data that can be used to parameterize macroscopic material models such as an anisotropic yield surface.

-# Installing Notes:
+[Materials.regions.model.ExaCMech]
+shortcut = "evptn_HCP_A"
 
-* git clone the LLNL BLT library into cmake directory. It can be obtained at https://github.com/LLNL/blt.git
-* MFEM will need to be built with hypre v2.26.0-v2.30.0; metis5; RAJA v2022.x+; and optionally Conduit, ADIOS2, or ZLIB.
-  * Conduit and ADIOS2 supply output support. ZLIB allows MFEM to read in gzip mesh files or save data as being compressed.
-  * You'll need to use the exaconstit-dev branch of MFEM found on this fork of MFEM: https://github.com/rcarson3/mfem.git
-  * We do plan on upstreaming the necessary changes needed for ExaConstit into the master branch of MFEM, so you'll no longer be required to do this
-  * Version 0.8.0 of ExaConstit is compatible with the following mfem hash:
-  31b42daa3cdddeff04ce3f59befa769b262facd7
-  or
-  29a8e15382682babe0f5c993211caa3008e1ec96
-  * Version 0.7.0 of Exaconstit is compatible with the following mfem hash 78a95570971c5278d6838461da6b66950baea641
-  * Version 0.6.0 of ExaConstit is compatible with the following mfem hash 1b31e07cbdc564442a18cfca2c8d5a4b037613f0
-  * Version 0.5.0 of ExaConstit required 5ebca1fc463484117c0070a530855f8cbc4d619e
-  * ExaCMech is required for ExaConstit to be built and can be obtained at https://github.com/LLNL/ExaCMech.git and now requires the develop branch. ExaCMech depends internally on SNLS, from https://github.com/LLNL/SNLS.git. We depend on v0.4.1 of ExaCMech as of this point in time.
-  * GPU-builds of ExaCMech >= v0.4.1 and thus ExaConstit now require the RAJA Portability Suite (RAJA, Umpire, and CHAI) to compile and run on the GPU. We currently leverage the `v2024.07.0` tag for all of the RAJA Portability Suite repos.
-  * For versions of ExaCMech >= 0.3.3, you'll need to add `-DENABLE_SNLS_V03=ON` to the cmake commands as a number of cmake changes were made to that library and SNLS.
-* RAJA is required for ExaConstit to be built and should be the same one that ExaCMech and MFEM are built with. It can be obtained at https://github.com/LLNL/RAJA. Currently, RAJA >= 2022.10.x is required for ExaConstit due to a dependency update in MFEMv4.5.
-* An example install bash script for unix systems can be found in ```scripts/install/unix_install_example.sh```. This is provided as an example of how to install ExaConstit and its dependencies, but it is not guaranteed to work on every system. A CUDA version of that script is also included in that folder (`unix_gpu_cuda_install_example.sh`), and only minor modifications are required if using a version of Cmake  >= 3.18.*. In those cases ```CUDA_ARCH``` has been changed to ```CMAKE_CUDA_ARCHITECTURES```. You'll also need to look up what you're CUDA architecture compute capability is set to and modify that within the script. Currently, it is set to ```sm_70``` which is associated with the Volta architecture. We also have a HIP version included in that folder (`unix_gpu_cuda_install_example.sh`). It's based on a LLNL El Capitan-like system build of things so things might need tweaking for other AMD GPU machines.

+## Output and Visualization
+
+### **Version 0.9 Output Updates**
+ExaConstit v0.9 introduces significant improvements to output management and file organization:
+
+#### **Modern Configuration Support**
+- **Legacy compatibility**: Previous option file formats continue to work
+- **Conversion utility**: Use our conversion script to migrate to the modern TOML format:
+  ```bash
+  python scripts/exaconstit_old2new_options.py old_options.toml -o new_options.toml
+  ```
+
+#### **Enhanced Output Files** 
+- **Headers included**: All simulation output files now contain descriptive headers
+- **Time and volume data**: Automatically included in all output files
+- **Improved format**: Enhanced data organization (note: format differs from previous versions)
+- **Basename-based directories**: Output location determined by `basename` setting in options file
+  ```toml
+  # if not provided defaults to option file name
+  basename = "exaconstit"  # Creates output directory: my_simulation/
+  ```
+
+#### **Advanced Visualization Control**
+- **Backward compatibility**: Visualization files remain compatible with previous versions
+- **User-friendly naming**: Visualization file names updated for better clarity  
+- **Selective field output**: Specify exactly which fields to save (new capability):
+  ```toml
+    [PostProcessing.projections]
+        # Some of these values are only compatible with ExaCMech
+        enabled_projections = ["stress", "von_mises", "volume", "centroid", "dpeff", "elastic_strain"]
+        # if set to true then all defaults are outputted by default
+        auto_enable_compatible = false
+  ```
+
+### **Migration Guide for Existing Users**
+- **Existing simulations**: Previous option files work without modification
+- **Output processing**: Update post-processing scripts to handle new file headers
+- **Directory structure**: Account for new basename-based output organization
+- **Visualization workflows**: Existing VisIt/ParaView workflows remain functional
+

Subject: [PATCH 064/146] Update the test suite and baselines Modified the
 baselines so that they all follow what the new tests look like and start
 moving it so that tests should be easier to compare against in the future
 Modified how the printing of all of the results look like so we have more
 precision and also so that all of the headers are centered Next remove the
 auto dt file since we include all of that info in the volume avg files
 anyways, so it was no longer needed Finally updated all of the test toml
 files so we just have the default outputs for everythings as we now output
 all of the data anyways to whatever the option file is called if a baseline
 is not included Also updated the multi-material data file to no longer do the
 visualizations and so we can get the outputs out

Subject: [PATCH 067/146] Update test results for multi-materials and fix issue
 with euler strains / elastic strains There was a bug in the euler strain
 calculations with the initial vdim being set to 6 but we needed it to be 9
 for the global avg calc before reducing it to the appropriate 6 dim val Next
 fixed the elastic strain baselines as they still had the incorrect values as
 they were 9 but needed to be 6 Updated the multi-material test so that it
 outputs more values so we have more interesting stuff to check against in our
 test suite

Subject: [PATCH 078/146] Fixes fun bug when running large enough cases where
 not all regions exist on every rank... So lots of crashes occur when you
 don't have every region on every rank... It turns out that MFEM is largely
 focused around working with MPI_WORLD_COMM and that all ParMeshes and
 ParGridFunctions and DataCollections and a few other things exist on all
 ranks even if you supply them an MPI_Comm... Outside of that we make use of
 MPI_Comms to only do work with ranks that also have the same region as it so
 we don't get some sorta weird issues with the volume average calculations A
 lot of time was spent working out the issues related to the MFEM assumptions
 in the PostProcessingDriver though... like way too much time...

Subject: [PATCH 085/146] Postprocessing updates (Regions # are now all 1-index
 and better viz names) So, I realized the region naming logic was pretty
 inconsistant so I updated it so we're constantly using index 1 everywhere as
 far as outputs goes. This does mean the region # in the options files needed
 updating but nothing crazy there. Outside of that, I updated the gridfunction
 names so they make use of the nicer display names instead and now the region
 names are removed but I might add those back in if people decide those are
 nicer... Due to making things all similar, I had to rename a ton of files
 which is why there are so many test file renames...

Subject: [PATCH 087/146] Claude helped: Add a new example options file based
 on new format Had Claude help in adding comments after I used the
 auto-converter script on things and manually updated all of the comments. It
 helped create a better documented options file that'll hopefully be easier
 for new users to parse and see how to implement things. Although, I still
 need to add some features such as some new solvers and actually let people
 define the preconditioner but shouldn't be too bad...

Subject: [PATCH 089/146] Add additional solvers and preconditioners for
 contrasting material systems Add some more non-symmetric krylov solvers
 (BiCGSTAB) Add a number of new preconditioners that should help for some
 highly contrasting multi-material systems such as ILU, l1-Gauss Seidel, and a
 Chebychev preconditioner.

Subject: [PATCH 090/146] Allow projections to be done per field now Added code
 path so that we can now pick and chose which fields we want outputted to
 users Additionally updated everything such that we only have a single class
 for all non-negative quantities. Also added the EPS as a default variable as
 well and updated the option file to provide understandable guidance for users

- * @brief Equivalent plastic strain rate projection for ECMech models
+ * @brief Post-processing projection for physically non-negative state variables
+ * 
+ * This class provides post-processing functionality for state variables that must be
+ * physically non-negative, ensuring numerical stability and physical consistency in
+ * finite element simulations. The projection applies a lower bound of zero to all
+ * computed values, preventing numerical artifacts from producing unphysical negative
+ * quantities.
+ * 
+ * @details
+ * During finite element computations, numerical errors, interpolation artifacts, or
+ * convergence issues can occasionally produce small negative values for quantities that
+ * should be strictly non-negative (e.g., equivalent plastic strain, damage parameters,
+ * void fractions). This projection enforces the physical constraint by applying:
+ * 
+ * \f$ \tilde{q} = \max(q, 0) \f$
  * 
- * Projects the equivalent plastic strain rate (dpeff) state variable from
- * ExaCMech constitutive models. This quantity represents the rate of
- * plastic strain accumulation and is essential for rate-dependent analysis.
+ * where \f$q\f$ is the computed state variable and \f$\tilde{q}\f$ is the corrected value.
  * 
- * Only compatible with ExaCMech material models that provide the
- * "eq_pl_strain_rate" state variable. Non-ECMech regions are handled
- * with dummy projections that produce no output.
+ * @note Currently optimized for ExaCMech constitutive models but designed to be
+ *       extensible to other material model frameworks requiring non-negative state variables.
  * 
- * Post-processing applies rate scaling and unit conversions as needed
- * for consistent output formatting across different material models.
+ * @par Typical Use Cases:
+ * - Equivalent plastic strain (\f$\varepsilon^p_{eq}\f$)
+ * - Damage variables (\f$D\f$)
+ * - Void fraction in porous materials (\f$f\f$)
+ * - Hardening variables (\f$\kappa\f$)
+ * - Any physically bounded scalar state variables
+ * 
+ * @par Performance Characteristics:
+ * - Device-compatible (GPU/CPU) through MFEM forall
+ * - O(N) complexity where N is the number of degrees of freedom
+ * - Supports global aggregation for parallel post-processing
+ * 
+ * @warning This projection modifies the computed field values. Ensure this is
+ *          appropriate for your analysis before enabling.

Subject: [PATCH 092/146] Generalize the lattice light up capabilities We now
 support more or less all of the crystallographic Laue groups that most people
 would need in a solid mechanics code. I took all of the various symmetry
 groups and reciprocal lattice parameter based on what was available in HEXRD.
 The only thing that I wasn't able to find in there was the Rhombohedral
 symmetry groups and for that I relied on Claude (which appears to likely be
 right as all the other groups matched up with what HEXRD provided...) I need
 to clean-up the comments to not be so Cubic centered and updated the main

Subject: [PATCH 094/146] Move ProjectionClass implementations to source file
 Finally got around to moving things out of the header file and move to the
 source file as things didn't need to all be in the header file. Still need to
 break up some more files such as the sim_state.hpp files to their own source
 files...

Subject: [PATCH 095/146] Move bigger funcs impl from simulation_state header
 to source Still had a number of function impls in the simulation_state.hpp
 file from when I was prototyping / just getting things working... I finally
 got to migrating them over to the source file but I still kept a number of
 the 3 liners in the header as they're pretty small. If they end up growing
 then I'll move them over...

Subject: [PATCH 098/146] Add a (claude generated) logger to decrowd outputs /
 save output and a few other fixes Used Claude to help generate a logger that
 would log any of our material model outputs to their own files per mpi rank,
 output any non-0 rank MFEM logging info to its own MPI rank file, and also
 duplicate all of the terminal output to its own logging file for future
 references. Outside of that had a few bug fixes captured in this that I
 noticed when running some tougher material models and hitting some
 interesting edge cases...

Subject: [PATCH 100/146] Fix some validation logic in options parser + better
 error messages The materials validation was missing quite a bit of logic as
 it looks like I never got to adding / fixing Claude's initial creation... We
 now actually properly validate things and pass it up the chain if something
 doesn't validate. So, we now check if the properties and state variables
 number of vars passed into match with what we tell it should be. If using an
 actual ECMech model we also verify that the property and state vars match up
 with what they should be and specify exactly with how many they should be.
 For the solvers, I updated some wording there as the preconditioners were out
 of date with what we actually support. I also added a check if the
 preconditioner for GPU rtmodels doesn't match up with JACOBI then we call
 that an issue. Should also add a check probably that we should be doing the
 same check for EA/PA assembly options as well... Fixed the error message for
 some stuff in the visualization tables Fixed the validation logic in the
 timing stuff as it wasn't as good as it could be and now at least throws an
 error if we have like a negative t_final or a value less than like the
 initial dt values...

Subject: [PATCH 101/146] Options update for only 1 rank printing and lots of
 fixes to validation stuff Should have checked this earlier but Claude was
 really bad doing the validation step... It largely just skipped them in a
 number of things so errors weren't being reported upwards. Additionally, I
 borrowed some of the logic of the logging to only have the root MPI rank
 report the errors / warnings / info. As part of this, I moved from MFEM_ABORT
 to mfem::mfem_error in the options for failed cases so I could have more
 control and only have the root rank print useful info out rather than having
 multiple ranks print out the same info. Added a lot more warnings /
 validation stuff so it's a bit simpler to figure out where things went wrong.
 Also hopefully for some of this things will fail sooner during validation for
 input errors rather than allowing things to make it into the actual
 simulation runs...

Subject: [PATCH 103/146] Fix file handling / creation when dealing with
 symlinks Ran into a number of issues with symlinks where things were being
 incorrectly handled so leveraged Claude for a fix to it. While I was at it I
 swapped over from strings for file handling to std::filesystem::path for most
 of them. It seems like this has simplified a lot of things and should make
 some things more platform independent as far as how directories are handled.

+
+/*
+OLD SYSTEM PROBLEMS:
+====================
+1. Complex template hierarchy with ProjectionTrait<Derived>
+2. Multiple registration methods: RegisterSimpleProjection, RegisterSpecialProjection, RegisterGeometryProjection
+3. Complicated trait detection and SFINAE
+4. Hard to understand inheritance and static dispatch
+5. Difficult to extend - need to understand the trait system
+6. Tightly coupled to specific PostProcessingDriver implementation
+
+NEW SYSTEM BENEFITS:
+====================
+1. Simple base class (ProjectionBase) with virtual methods
+2. Three clear categories: GeometryProjection, StressProjection, StateVariableProjection
+3. Easy to extend - just inherit from the appropriate base class
+4. Clean runtime polymorphism - no template metaprogramming required
+5. Simple registration: just RegisterProjection(name, std::make_unique<YourProjection>())
+6. Easy to test individual projections
+7. Self-contained projections that know their requirements
+8. Clear separation of concerns
+
+ADDING A NEW PROJECTION:
+========================
+OLD: 
+- Create trait class inheriting from ProjectionTrait<T>
+- Implement static methods: GetModelCompatibility, SelectComponent, PostProcess, CanAggregateGlobally
+- Understand which registration method to use
+- Deal with template instantiation and compatibility checking
+
+NEW:
+- Inherit from appropriate base (GeometryProjection, StressProjection, or StateVariableProjection)
+- Implement virtual methods (much clearer interface)
+- Register with a single method call
+- Done!
+
+EXTENDING FOR NEW CATEGORIES:
+=============================
+If you need a new category of projections (e.g., time-derivative based):
+
+class TimeDerivativeProjection : public ProjectionBase {
+public:
+    void Execute(SimulationState& sim_state, 
+                mfem::ParGridFunction& grid_function, 
+                int region) override {
+        // Get current and previous state, compute derivatives
+        auto current_qf = sim_state.GetQuadratureFunction(m_var_name, region);
+        auto previous_qf = sim_state.GetPreviousQuadratureFunction(m_var_name, region);
+        
+        // Compute time derivative and project
+        ComputeTimeDerivative(*current_qf, *previous_qf, grid_function);
+    }
+    
+protected:
+    virtual void ComputeTimeDerivative(const mfem::PartialQuadratureFunction& current,
+                                      const mfem::PartialQuadratureFunction& previous,
+                                      mfem::ParGridFunction& grid_function) = 0;
+    std::string m_var_name;
+};
+
+Then implement specific time derivative projections by inheriting from this base.

Subject: [PATCH 104/146] Update LightUp option parsing for when
 multi-materials / regions have same material name Previously, we only allowed
 the light up options to require unique material names. However, we didn't
 have any such restrictions in the actual material blocks. I've now updated
 this such that we can use a single light up block for material blocks with
 all of the same material name. The assumption here is that there might be
 slight differences or none at all if the material names are the same in our
 material blocks. However, the light up blocks would all have the same
 parameters / name. We might change this in the future but for now things are
 good as we'll duplicate the blocks and allow such cases as our file output
 makes unique file names for everything. Outside of the above, I also hardened
 the input parsing aspect of things as the TOML parser is a bit brittle and
 might parse numbers as ints and then crash on us if we want a double. So, I
 now parse for both cases and internally convert to doubles for everyone which
 solves the issues for the HKL and sample directions for everything.

-**Algebraic Multigrid (AMG)**:
-- **BoomerAMG**: HYPRE implementation
-- **Scalable**: Excellent for large-scale problems
-- **Setup cost**: Requires matrix assembly
-
-**Jacobi Preconditioning**:
-- **Matrix-free**: Compatible with PA and EA assembly
-- **Simple**: Diagonal scaling preconditioning and generally good enough for solid mechanics problems
-- **GPU friendly**: Efficient device implementation
+**Assembly-Dependent Availability:**
+
+For **PA/EA Assembly** (limited to):
+- **JACOBI**: Diagonal scaling, GPU-compatible (automatic selection)
+
+For **FULL Assembly** (all options available):
+- **JACOBI**: Diagonal scaling
+- **AMG**: Algebraic multigrid
+- **ILU**: Incomplete LU factorization  
+- **L1GS**: ℓ¹-scaled Gauss-Seidel
+- **CHEBYSHEV**: Polynomial smoother
+
+**Preconditioner Details:**
+
+**JACOBI** (Diagonal Scaling):
+- **Characteristics**: Simple and fast, works everywhere but slow convergence
+- **Assembly**: Works with PA, EA, and FULL
+- **GPU**: Fully GPU-compatible
+- **Use case**: Default for PA/EA assembly, baseline option
+
+**AMG** (Algebraic Multigrid):
+- **Characteristics**: Fewer iterations but expensive setup, can fail on some problems
+- **Implementation**: HYPRE BoomerAMG
+- **Configuration**: Pre-tuned for 3D elasticity
+- **Use case**: Large-scale problems with single materials
+
+**ILU** (Incomplete LU Factorization):
+- **Characteristics**: Good middle-ground option
+- **Implementation**: HYPRE Euclid
+- **Use case**: Particularly useful for multi-material systems
+- **Try this**: If JACOBI convergence is too slow
+
+**L1GS** (ℓ¹-Scaled Gauss-Seidel):
+- **Characteristics**: Advanced smoother
+- **Implementation**: HYPRE smoother
+- **Use case**: Multi-material systems with contrasting properties
+- **Try this**: When materials have very different stiffness values
+
+**CHEBYSHEV** (Chebyshev Polynomial):
+- **Characteristics**: Polynomial smoother
+- **Implementation**: HYPRE smoother
+- **Use case**: Problems with multiple material scales
+- **Try this**: For heterogeneous material distributions
+
+**Practical Selection Guidelines:**
+
+For **Single Material Problems**:
+- Start with JACOBI (simple, predictable)
+- Try AMG if convergence is slow
+- Use ILU as a reliable alternative
+
+For **Multi-Material Systems**:
+- Start with ILU (good middle-ground)
+- Try L1GS for contrasting material properties
+- Use CHEBYSHEV for multiple material scales
+- AMG may struggle with material interfaces
+
+**Performance Tips**:
+- PA/EA assembly automatically uses JACOBI
+- If JACOBI convergence is too slow with FULL assembly, try ILU → L1GS → CHEBYSHEV
+- AMG has high setup cost but fewer iterations
+- Multi-material systems often benefit from experimenting with different preconditioners

-// COMPARISON: OLD vs NEW SYSTEM
-//=============================================================================
-
-/*
-OLD SYSTEM PROBLEMS:
-====================
-1. Complex template hierarchy with ProjectionTrait<Derived>
-2. Multiple registration methods: RegisterSimpleProjection, RegisterSpecialProjection, RegisterGeometryProjection
-3. Complicated trait detection and SFINAE
-4. Hard to understand inheritance and static dispatch
-5. Difficult to extend - need to understand the trait system
-6. Tightly coupled to specific PostProcessingDriver implementation
-
-NEW SYSTEM BENEFITS:
-====================
-1. Simple base class (ProjectionBase) with virtual methods
-2. Three clear categories: GeometryProjection, StressProjection, StateVariableProjection
-3. Easy to extend - just inherit from the appropriate base class
-4. Clean runtime polymorphism - no template metaprogramming required
-5. Simple registration: just RegisterProjection(name, std::make_unique<YourProjection>())
-6. Easy to test individual projections
-7. Self-contained projections that know their requirements
-8. Clear separation of concerns
-
-ADDING A NEW PROJECTION:
-========================
-OLD: 
-- Create trait class inheriting from ProjectionTrait<T>
-- Implement static methods: GetModelCompatibility, SelectComponent, PostProcess, CanAggregateGlobally
-- Understand which registration method to use
-- Deal with template instantiation and compatibility checking
-
-NEW:
-- Inherit from appropriate base (GeometryProjection, StressProjection, or StateVariableProjection)
-- Implement virtual methods (much clearer interface)
-- Register with a single method call
-- Done!
-
-EXTENDING FOR NEW CATEGORIES:
-=============================
-If you need a new category of projections (e.g., time-derivative based):
-
-class TimeDerivativeProjection : public ProjectionBase {
-public:
-    void Execute(SimulationState& sim_state, 
-                mfem::ParGridFunction& grid_function, 
-                int region) override {
-        // Get current and previous state, compute derivatives
-        auto current_qf = sim_state.GetQuadratureFunction(m_var_name, region);
-        auto previous_qf = sim_state.GetPreviousQuadratureFunction(m_var_name, region);
-        
-        // Compute time derivative and project
-        ComputeTimeDerivative(*current_qf, *previous_qf, grid_function);
-    }
-    
-protected:
-    virtual void ComputeTimeDerivative(const mfem::PartialQuadratureFunction& current,
-                                      const mfem::PartialQuadratureFunction& previous,
-                                      mfem::ParGridFunction& grid_function) = 0;
-    std::string m_var_name;
-};
-
-Then implement specific time derivative projections by inheriting from this base.

Subject: [PATCH 108/146] (Claude) Beef up the UMAT handling / dload aspect of
 things Since spent enough time getting the dynamic umat loader stuff working
 decided to just port that over to our internal UMAT stack as that way I don't
 have to keep trying to figure out compiler name mangling when moving between
 compilers... Now at runtime it figures it out for us on the first call and
 then saves that for future calls. I had Claude help with this aspect of
 things. It also includes some debugging aspect to make it easy to figure out
 where something is coming from. Then if it can't find a function call as
 there might be a mistake in the user provided options it'll search the
 library for a number of different typical umat function names and if it finds
 one it'll use it. Although, we do warn the user about this.

I've also been working on a better UMAT wrapper example and will likely upload that at some point for users in the near term as it also just finds the UMAT func name for them and makes things simpler not harder.
Outside of that there were some minor issues with the dynamic library accidentally not finding the library paths that we wanted and ultimately calling our internal umat as it was ignoring the path we provided.

Subject: [PATCH 111/146] [Claude] Modify UMAT dynamic loader framework for
 unification of things A lot of the UMAT dynamic library framework was
 redundant from one to another. So, I had Claude help generate a unified
 version of what was in the userumat.* and dynamic_umat_loader.* cases. This
 new version now works for both the basic and dynamic loaded version. The new
 dynamic_function_loader set of classes should also help when we want to later
 expand to allow for other dynamic library / function loading for things like
 post-processing or other things of that nature...

Subject: [PATCH 115/146] Tons of compiler warning fixes related to implicit
 type conv / other fixes Largely fixing all of the issues that the following
 set of compiler warnings brought up: -Wall -Wextra -Wshadow
 -Wnon-virtual-dtor -Wold-style-cast -Wcast-align -Wunused
 -Woverloaded-virtual -Wpedantic -Wconversion -Wsign-conversion
 -Wnull-dereference -Wdouble-promotion -Wformat=2 Took these recommended
 warnings from a reddit post found online to try and cover my bases...
 Additionally, I also addressed some GitHub CI warnings that I was seeing in
 the CI side of things. Largely most of these just boiled down to implicit
 changes from int to size_t or vice versa or some other "minor"-ish type
 conversions There were a few ones mentioning using old cast type methods
 which was the (T) U type casting and moving over to static_cast<T>(U).

-"""
-Migration script for ExaConstit option files from old format to new format.
-Converts old option_parser.cpp/hpp TOML format to option_parser_v2.cpp/hpp format.
-
-Key features:
-- Handles case-insensitive option values from old parser
-- Normalizes solver names (e.g., PCG -> CG)
-- Converts various spelling variations to canonical v2 format
-- Normalizes boolean values (true/True/TRUE/yes/1 -> true)
-- Preserves backward compatibility while enforcing v2 conventions
-
-The script automatically handles common variations in:
-- Solver types (PCG->CG, various cases)
-- Assembly modes (pa/PA, full/FULL, etc.)
-- Material models (ExaCMech/exacmech/EXACMECH)
-- Crystal types (fcc/FCC/Fcc)
-- Boolean values (true/True/yes/1/on)
-- And many more...

Subject: [PATCH 122/146] Vast formatting changes for consistency everywhere
 more or less in at least fcn capitalization For anything that is not IO
 related (anything but src/options and src/utilities/unified_logger.*) all the
 function signatures have been converted to "PascalCase" in-order to be
 consistent with how MFEM does things and just standardize things.

IO related files (src/options/* and src/utilities/unified_logger.*) all of the functions were set to "snake_case" as this was cleaner looking for the options work and then for the loggers it better matched what the STDLIB is doing which makes things easier to read / reason about. I honestly would prefer all functions signatures look like this but with how MFEM does things that just clashed too much everywhere else :(

Now there were also some member variable name changes any member variable that ended with the postfix "_" had that postfix removed. This addition is something that Claude just loves to add... and I finally got a round to removing them. I still need to make the member variable names consistent everywhere but that will likely be a fight for another day...

Note, I did try using clang-tidy to enforce this automatically but it kept getting too many things wrong or changing too much. So, I just abandonded that idea of using it as a tool to automatically do this for us. I might still look into using it for other things though as well as leveraging like clang-format.

- * @param DS Dense matrix containing shape function derivatives in physical coordinates
- * @param Bgeom Output B-matrix for geometric operations (modified in place)
- * @param dof Number of degrees of freedom per element
+ * @param deriv_shapes Dense matrix containing shape function derivatives in physical coordinates (∂N/∂x)
+ * @param elem_deriv_shapes Dense matrix containing element-averaged shape function derivatives (∂N̄/∂x)
+ * @param B Output B-bar matrix relating nodal displacements to strain components (modified in place)
  * 
- * This function constructs the geometric B-matrix used in finite element assembly
- * operations, particularly for computing element stiffness matrices and residual
- * vectors. The B-matrix relates nodal displacements to strain measures through
- * the relationship: strain = B * nodal_displacements.
+ * This function constructs the B-bar matrix using the classical Hughes formulation for
+ * treating nearly incompressible materials. The B-bar method applies selective reduced
+ * integration by splitting the strain into volumetric and deviatoric components, then
+ * using element-averaged shape function derivatives for the volumetric part while
+ * retaining full integration for the deviatoric part.
+ * 
+ * The B-bar matrix is constructed using the decomposition:
+ * B̄ = B_dev + B_vol
+ * 
+ * where:
+ * - B_dev represents the deviatoric strain contribution (full integration)
+ * - B_vol represents the volumetric strain contribution (reduced integration via averaging)
+ * 
+ * The volumetric modification is applied to the normal strain components through:
+ * B̄_ii = B_ii + (∂N̄/∂x_i - ∂N/∂x_i)/3
  * 
- * The function builds the B-matrix in blocks corresponding to the three spatial
- * dimensions, following MFEM's internal vector ordering: [x0...xn, y0...yn, z0...zn].
- * This organization is optimized for MFEM's assembly operations and vectorization.
+ * where the factor of 1/3 distributes the volumetric correction equally across the
+ * three normal strain components, ensuring proper treatment of the volumetric constraint
+ * for nearly incompressible materials.
  * 
  * Matrix structure for 3D elements:
- * - Rows: 3*dof (all DOFs for all nodes)
- * - Columns: 9 (components of 3x3 tensor, e.g., stress or strain)
- * - Block structure enables efficient computation of B^T * Sigma * B
+ * - Input deriv_shapes: (dof × 3) matrix of shape function derivatives at integration point
+ * - Input elem_deriv_shapes: (dof × 3) matrix of element-averaged shape function derivatives
+ * - Output B: (3*dof × 6) matrix in Voigt notation order
+ * - Strain ordering: [ε_xx, ε_yy, ε_zz, γ_xy, γ_xz, γ_yz]
  * 
- * The B-matrix can be used in operations like:
- * - K_element = ∫ B^T * C * B dV (stiffness matrix)
- * - F_element = ∫ B^T * σ dV (internal force vector)
+ * The B-bar matrix structure for each node i follows the pattern:
+ * ```
+ * [B̄₁ + ∂N_i/∂x    B̄₁           B̄₁         0         ∂N_i/∂z   ∂N_i/∂y]  <- x-displacement DOF
+ * [    B̄₂       B̄₂ + ∂N_i/∂y    B̄₂      ∂N_i/∂z      0        ∂N_i/∂x]  <- y-displacement DOF  
+ * [    B̄₃           B̄₃       B̄₃ + ∂N_i/∂z ∂N_i/∂y   ∂N_i/∂x      0    ]  <- z-displacement DOF
+ * ```
+ * 
+ * where B̄ₖ = (∂N̄_i/∂x_k - ∂N_i/∂x_k)/3 for k = 1,2,3
+ * 
+ * Note that the shear strain components (columns 4-6) use the standard B-matrix
+ * formulation without volumetric correction, as they do not contribute to volumetric
+ * deformation.
  * 
- * where C is the material tangent matrix and σ is the stress tensor.
+ * This formulation effectively prevents volumetric locking in low-order elements
+ * (such as linear hexahedra and tetrahedra) when analyzing nearly incompressible
+ * materials with Poisson's ratios approaching 0.5.
+ * 
+ * @note This function assumes 3D elements and unrolls loops for performance.
+ * @note The elem_deriv_shapes matrix should contain element-averaged derivatives: ∂N̄/∂x = (1/V)∫_V ∂N/∂x dV.
+ * @note The B matrix must be pre-sized to (3*dof, 6) before calling this function.
+ * @note For compressible materials, this reduces to the standard B-matrix as elem_deriv_shapes → deriv_shapes.

  * @brief B-bar method integrator for incompressible and nearly incompressible solid mechanics.
- * 
+ *
  * ICExaNLFIntegrator extends ExaNLFIntegrator to implement the B-bar method for handling
  * incompressible and nearly incompressible materials. This integrator is essential for
  * crystal plasticity simulations where volume preservation constraints arise from
  * incompressible plastic deformation or nearly incompressible elastic behavior.
- * 
+ *
  * The B-bar method (Hughes, 1980):
  * - Modifies the strain-displacement B-matrix to avoid volumetric locking
  * - Uses volume-averaged dilatational strains to improve element performance
  * - Maintains accuracy for incompressible and nearly incompressible materials
  * - Enables stable finite element solutions for high bulk modulus problems
- * 
+ *
  * Mathematical foundation:
  * The B-bar method splits the strain into volumetric and deviatoric parts:
  * ε = ε_vol + ε_dev, where ε_vol is volume-averaged over the element
- * 
+ *
  * This approach prevents spurious pressure oscillations and volumetric locking
  * that can occur with standard displacement-based finite elements when dealing
  * with incompressible or nearly incompressible material behavior.
- * 
+ *
  * Applications in crystal plasticity:
  * - Incompressible plastic deformation in crystal slip
  * - Nearly incompressible elastic response in metals
  * - Volume-preserving deformation in single crystal simulations
  * - Polycrystalline materials with incompressible phases
- * 
+ *
  * Key features:
  * - Inherits all standard solid mechanics capabilities from ExaNLFIntegrator
  * - Modifies B-matrix construction for volumetric strain averaging
  * - Maintains compatibility with all assembly strategies (PA, EA, standard)
  * - Provides stable solutions for high bulk modulus materials
  * - Supports large deformation kinematics with volume preservation
- * 
+ *
  * Implementation details:
  * - Computes element-averaged volumetric strain gradients
  * - Modifies standard B-matrix with B-bar corrections
  * - Uses Hughes' formulation from "The Finite Element Method" Section 4.5.2
  * - Maintains computational efficiency comparable to standard elements

 /**
  * @brief L1-Jacobi smoothing preconditioner for mechanics finite element operators.
- * 
+ *
  * MechOperatorJacobiSmoother implements an efficient Jacobi-type preconditioner specifically
  * designed for mechanics problems with essential boundary conditions. The preconditioner
  * uses diagonal scaling with damping to provide effective preconditioning for iterative
  * linear solvers in Newton-Raphson frameworks.
- * 
+ *
  * Key features for mechanics applications:
  * - L1-Jacobi scaling for improved convergence on mechanics problems
  * - Proper essential boundary condition handling with identity scaling
  * - Damping parameter for stability control and convergence tuning
  * - Device-compatible implementation for GPU acceleration
  * - Integration with partial and element assembly operators
- * 
+ *
  * The L1-Jacobi approach:
  * - Uses L1 norm of matrix rows for diagonal approximation when full diagonal unavailable
  * - Provides more robust scaling than simple Jacobi for some problem types
  * - Incorporates damping for stability in challenging nonlinear problems
  * - Handles essential boundary conditions through identity preconditioning
- * 
+ *
  * Essential boundary condition treatment:
  * - Essential DOFs receive identity preconditioning (scaling factor = damping)
  * - Maintains consistency with constrained operator structure
  * - Preserves constraint satisfaction during iterative solution
  * - Prevents ill-conditioning from constraint enforcement
- * 
+ *
  * Performance characteristics:
  * - Setup cost: O(ndof) diagonal inverse computation
  * - Application cost: O(ndof) scaled vector addition
  * - Memory usage: O(ndof) for diagonal storage
  * - Device execution: Full GPU compatibility for large-scale problems

  * @brief Class for representing quadrature functions on a subset of mesh elements.
- * 
+ *
  * PartialQuadratureFunction extends MFEM's QuadratureFunction to efficiently store and
  * manipulate quadrature point data for only a subset of mesh elements. This is essential
  * in ExaConstit for multi-material simulations where different constitutive models and
  * state variables apply to different regions of the mesh.
- * 
+ *
  * The class maintains compatibility with MFEM's QuadratureFunction interface while
  * providing optimized memory usage and performance for partial element sets. It handles
  * the mapping between partial and full quadrature spaces automatically and provides
  * default values for elements not in the partial set.
- * 
+ *
  * Key features:
  * - Memory-efficient storage for sparse element data
  * - Automatic handling of default values for non-partial elements
  * - Full compatibility with MFEM's QuadratureFunction operations
  * - Efficient data transfer between partial and full quadrature spaces
  * - Support for multi-component vector fields at quadrature points

  * @brief Class representing a subset of a QuadratureSpace for efficient operations on subdomains.
- * 
+ *
  * PartialQuadratureSpace extends MFEM's QuadratureSpaceBase to provide efficient finite element
  * operations on subsets of mesh elements. This is particularly useful in ExaConstit for handling
  * multi-material simulations where different constitutive models apply to different regions of
  * the mesh (e.g., different crystal orientations in polycrystalline materials).
- * 
+ *
  * The class maintains bidirectional mappings between local element indices (within the partial set)
  * and global element indices (in the full mesh), enabling efficient data access and computation
  * while maintaining compatibility with MFEM's finite element framework.
- * 
+ *
  * Key features:
  * - Efficient memory usage by storing data only for active elements
  * - Optimized performance through local-to-global index mapping
  * - Full compatibility with MFEM's QuadratureSpaceBase interface
  * - Support for both partial and full mesh coverage with automatic optimization

  * Key responsibilities:

  * 4. Aggregate results from child models into global data structures
  * 5. Present a unified ExaModel interface to external code
- * 
+ *
  * This design eliminates the need for external classes (like NonlinearMechOperator)

  * Key features:
  * - Accurate volume calculation for arbitrary element geometries
  * - Support for high-order finite elements through appropriate integration rules
  * - Essential for volume-weighted averaging operations in post-processing
  * - Useful for mesh quality assessment and adaptive refinement criteria

  * @brief Post-processing projection for physically non-negative state variables
- * 
+ *
  * This class provides post-processing functionality for state variables that must be
  * physically non-negative, ensuring numerical stability and physical consistency in

  * computed values, preventing numerical artifacts from producing unphysical negative
  * quantities.
- * 
+ *
  * @details
  * During finite element computations, numerical errors, interpolation artifacts, or
  * convergence issues can occasionally produce small negative values for quantities that
  * should be strictly non-negative (e.g., equivalent plastic strain, damage parameters,
  * void fractions). This projection enforces the physical constraint by applying:
- * 
+ *
  * \f$ \tilde{q} = \max(q, 0) \f$
- * 
+ *
  * where \f$q\f$ is the computed state variable and \f$\tilde{q}\f$ is the corrected value.
- * 
+ *
  * @note Currently optimized for ExaCMech constitutive models but designed to be
  *       extensible to other material model frameworks requiring non-negative state variables.
- * 
+ *
  * @par Typical Use Cases:
  * - Equivalent plastic strain (\f$\varepsilon^p_{eq}\f$)
  * - Damage variables (\f$D\f$)
  * - Void fraction in porous materials (\f$f\f$)
  * - Hardening variables (\f$\kappa\f$)
  * - Any physically bounded scalar state variables
- * 
+ *
  * @par Performance Characteristics:
  * - Device-compatible (GPU/CPU) through MFEM forall
  * - O(N) complexity where N is the number of degrees of freedom
  * - Supports global aggregation for parallel post-processing

  * @brief Line search Newton implementation
- * 
+ *
  * @details The line search algorithm implementation:
- * 
+ *
  * **Quadratic Line Search Theory**:
  * Given three points and their residual norms (q1, q2, q3), the algorithm
  * fits a quadratic polynomial q(s) = as² + bs + c to find the minimum.
  * The optimal step size is: ε = -b/(2a) = (3*q1 - 4*q2 + q3) / (4*(q1 - 2*q2 + q3))
- * 
+ *
  * **Robustness Checks**:
  * - Validates quadratic fit: (q1 - 2*q2 + q3) > 0 (convex)
  * - Bounds step size: 0 < ε < 1 (reasonable range)
  * - Fallback logic when quadratic fit fails
- * 
+ *
  * **Performance Profiling**:
  * - "NRLS_solver" scope for overall line search Newton performance
  * - "Line Search" scope specifically for step size computation
  * - "krylov_solver" scope for linear solver calls
- * 
+ *
  * **Memory Management**:
  * - Uses device-compatible temporary vectors (x_prev, Jr)
  * - Efficient vector operations with MFEM's device interface
- * 
+ *
  * **Failure Handling**:
  * - Scale factor of 0.0 triggers immediate convergence failure
  * - Graceful degradation when line search produces invalid results

  * This approach is particularly useful for:
  * - Large deformation problems with geometric nonlinearities
  * - Material models with strong nonlinearities (e.g., plasticity, damage)
  * - Problems where standard Newton-Raphson exhibits oscillatory behavior
- * 
+ *
  * The method GetGradient() must be implemented for the operator F.
  * The preconditioner is used (in non-iterative mode) to evaluate
  * the action of the inverse gradient of the operator.

 /**
  * @brief Primary driver class for ExaConstit's velocity-based finite element simulations.
- * 
+ *
  * SystemDriver orchestrates the entire nonlinear mechanics simulation workflow for ExaConstit,
  * implementing a velocity-based, updated Lagrangian finite element framework for solid mechanics
  * problems with emphasis on crystal plasticity and micromechanics modeling. The class manages
  * the Newton-Raphson solution process, boundary condition enforcement, and model state updates
  * throughout the simulation.
- * 
+ *
  * The driver integrates multiple components:
  * - Newton-Raphson nonlinear solver with optional line search
  * - Krylov iterative linear solvers (GMRES, CG, MINRES) with preconditioning
  * - Essential boundary condition management (velocity and velocity gradient BCs)
  * - Constitutive model integration and state variable updates
  * - Device-aware execution supporting CPU, OpenMP, and GPU backends
- * 
+ *
  * Key simulation capabilities:
  * - Multi-material nonlinear solid mechanics with large deformations
  * - Crystal plasticity simulations with grain-specific material behavior
  * - Complex loading conditions including velocity gradient boundary conditions
  * - Automated time stepping with adaptive control
  * - Parallel MPI execution with domain decomposition
- * 
+ *
  * The class follows the MFEM finite element framework conventions while extending
  * functionality for ExaConstit's specialized micromechanics applications. It serves
  * as the central coordination point between mesh management, material models,
  * solvers, and postprocessing systems.

  * This function constructs the B-bar matrix using the classical Hughes formulation for

  * Data layout assumptions:
  * - Data is stored element-by-element
  * - Within each element, data is stored point-by-point
  * - Within each point, components are stored sequentially

  * Usage example:
  * @code
  * double stress[6];  // For symmetric stress tensor
  * GetQFData(elem_id, qp_id, stress, stress_qf);

  * - Input: Standard QF layout with material gradients per quadrature point
  * - Output: 4D RAJA view layout optimized for partial assembly kernels
  * - Uses permuted layouts to optimize memory access patterns
- *

- * 
+ *
  * This template function computes volume-averaged values of tensor quantities
  * stored at quadrature points. It supports both simple averaging and proper
  * volume-weighted averaging depending on the template parameter.
- * 
+ *
  * The volume averaging computation follows:
  * <T> = (∫ T(x) dV) / (∫ dV) = (∑ T_qp * |J_qp| * w_qp) / (∑ |J_qp| * w_qp)
- * 
+ *
  * where:
  * - T(x) is the tensor field to be averaged
  * - T_qp are the tensor values at quadrature points
  * - |J_qp| are the Jacobian determinants at quadrature points
  * - w_qp are the quadrature weights
- * 
+ *
  * Algorithm steps:
  * 1. Set up RAJA views for efficient memory access patterns
  * 2. Loop over all elements and quadrature points
  * 3. Accumulate weighted tensor values and total volume
  * 4. Normalize by total volume if vol_avg is true
- * 
+ *
  * Template behavior:
  * - vol_avg = true: Performs proper volume averaging (tensor /= total_volume)
  * - vol_avg = false: Returns volume-weighted sum without normalization
- * 
+ *
  * This function is essential for:
  * - Computing homogenized material properties
  * - Extracting representative volume element (RVE) responses
  * - Postprocessing stress and strain fields
  * - Volume averaging for multiscale analysis
- * 
+ *
  * @note The tensor vector is resized automatically to match the size parameter.

  * This template function provides filtering capability for full mesh

- *

  * - Partial mesh processing (ComputeVolAvgTensorFromPartial)
  * - Filtered partial processing (ComputeVolAvgTensorFilterFromPartial)
- * 
+ *
  * Use cases include:

  * - Dynamic filtering where partial spaces are not pre-defined
  * - Multi-criteria filtering across the entire domain
  * - Exploratory data analysis on full simulation results
- * 
+ *
  * Performance considerations:
  * - Processes entire mesh but conditionally accumulates
  * - More memory bandwidth than partial space alternatives
  * - Suitable when filter changes frequently or is complex
  * - RAJA views optimize memory access patterns
- * 
+ *
  * The filter array organization follows standard QuadratureFunction layout:
  * - Element-major ordering: filter[elem][qp]
  * - Total size: nqpts * nelems
  * - Boolean values minimize memory footprint
- * 
+ *
  * Integration with ExaConstit workflows:
  * - Supports all material models and integration rules
  * - Compatible with existing postprocessing infrastructure
  * - Enables gradual migration to partial space architectures
  * - Returns volume for consistency with other averaging functions

  * @note Performance scales with total mesh size, not filtered size.
  * @note Return volume enables multi-region volume fraction calculations.

  * This template function extends ComputeVolAvgTensorFromPartial by adding
  * point-wise filtering capability. It computes volume averages over only
  * those quadrature points where the filter array is true, enabling selective
  * postprocessing based on material state, stress levels, or other criteria.
- * 
+ *
  * Filtering applications:
  * - Stress-based filtering (e.g., only plastic regions)
  * - Phase-specific averaging in multiphase materials
  * - Damage-based selective averaging
  * - Grain-specific calculations in polycrystals
  * - Temperature or strain-rate dependent processing
- * 
+ *
  * Algorithm with filtering:
  * 1. Loop over all local elements in the PartialQuadratureFunction
  * 2. For each quadrature point, check the filter condition
  * 3. Include only filtered points in volume and tensor accumulation
  * 4. Normalize by filtered volume if vol_avg is true
- * 
+ *
  * The filter array indexing must match the quadrature point layout:
  * - One boolean value per quadrature point
  * - Organized element-by-element, then point-by-point within elements
  * - Size should equal nqpts * nelems for the partial space
- * 
+ *
  * Memory efficiency considerations:
  * - Filter array can be generated on-the-fly or cached
  * - Boolean filter minimizes memory overhead
  * - Processing only active points reduces computational cost
- * 
+ *
  * Return value enables cascaded filtering operations and
  * provides volume information for normalization in subsequent
  * calculations or multiscale homogenization procedures.
- * 
+ *
  * @note Filter array size must match total quadrature points in partial space.
  * @note Filtering reduces computational cost but adds conditional overhead.
  * @note Zero filtered volume will result in division by zero if vol_avg is true.

  * 3. Extracts the rotation axis from the skew-symmetric part of the matrix
  * 4. Constructs the quaternion using the half-angle formulation

  * The quaternion representation uses the convention:
  * - quat[0] = cos(φ/2) (scalar part)

  * - Crystal plasticity simulations requiring orientation tracking
  * - Rigid body kinematics and rotational mechanics
  * - Interpolation between rotational states
  * - Integration of rotational differential equations

Subject: [PATCH 142/146] [Claude] unify our various build scripts to share
 tons of things Tired of having small differences in the build scripts across
 everything so had Claude help generate a unified set of build scripts based
 on a new refactored build script I also had generated from another LLM. Now
 pretty much everything is shared between them and we just have some simple
 config files created for new systems and very simple install scripts that
 look similar between all systems.

Subject: [PATCH 143/146] [Claude] Generated documentation related to
 installation / using provided build scripts Claude helped generate
 documentation for all of the build scripts and how to use them. The
 documentation is pretty extensive which is why we now have a doc directory.
 Hopefully the new documentation makes it easier for people to get started /
 have something they can work more towards with their own build systems.

 ### Installation
 
-#### **Linux/Unix Systems**
+ExaConstit provides automated installation scripts for different platforms. For detailed instructions, see [Installation Guide](docs/install.md).
+
+#### Quick Start
+
+**Linux (Intel CPU)**
+```bash
+./scripts/install/unix_cpu_intel_install.sh
+```
+
+**macOS**
 ```bash
-# Use our convenient install script
-./scripts/install/unix_install_example.sh
+./scripts/install/unix_cpu_mac_install.sh
 ```
 
-#### **GPU-Accelerated Build (CUDA)**
+**NVIDIA GPU (CUDA)**
 ```bash
-# NVIDIA GPU systems
-./scripts/install/unix_gpu_cuda_install_example.sh
+./scripts/install/unix_gpu_cuda_install.sh
 ```
 
-#### **GPU-Accelerated Build (HIP/AMD)**  
+**AMD GPU (HIP/ROCm)**
 ```bash
-# AMD GPU systems
-./scripts/install/unix_gpu_hip_install_example.sh
+./scripts/install/unix_gpu_hip_install.sh
 ```
 
-Note: if you are running on MI300a systems, we have found that the HSA_XNACK=1 flag is required to properly run simulations due to limitations we have found in MFEM and elsewhere.
+#### Before First Run
+
+⚠️ **You must customize the build configuration for your system.**
+
+Edit the appropriate config file in `scripts/install/configs/` and update:
+- Compiler paths and versions
+- MPI installation location
+- Python executable path
+- Module load commands (HPC systems)
+
+See the [Installation Guide](docs/install.md) for detailed setup instructions.
+
+#### Build Options
+```bash
+# Clean rebuild

+
+## Build System Architecture
+
+The installation framework is organized into three components:
+```
+scripts/install/
+├── common/
+│   ├── dependency_versions.sh    # Centralized version control
+│   ├── preflight_checks.sh       # Validation and utilities
+│   └── build_functions.sh        # Shared build logic

+│   └── gpu_hip_config.sh         # AMD HIP configuration
+└── unix_*_install.sh              # Platform-specific entry points
+```
+
+- **common/**: Shared build logic used across all platforms
+- **configs/**: Platform-specific compiler paths, flags, and settings
+- **Entry scripts**: Simple launchers that source the appropriate config and common functions
+
+---
+
+## First-Time Setup
+
+Before running an install script, you'll need to customize the configuration file for your system.
+
+### **Step 1: Edit the Configuration File**
+
+Navigate to the ExaConstit repository and open the appropriate config file in `scripts/install/configs/` with either a built in editor or something like VSCode:
+```bash
+cd ExaConstit
+
+# For Intel CPU builds
+code scripts/install/configs/cpu_intel_config.sh
+
+# For CUDA GPU builds
+code scripts/install/configs/gpu_cuda_config.sh
+
+# For HIP/AMD GPU builds
+code scripts/install/configs/gpu_hip_config.sh
+
+# For macOS builds
+code scripts/install/configs/cpu_mac_config.sh
+```
+
+### **Step 2: Update Compiler Paths and Versions**
+
+Each config file has a clearly marked section at the top for system-specific paths. Update these for your environment:
+
+#### **Intel CPU Configuration Example**
+```bash
+###########################################
+# Compiler Versions and Base Paths
+###########################################
+INTEL_VERSION="2023.2.1-magic"                    # Update to your Intel version
+COMPILER_VERSION="intel-${INTEL_VERSION}"
+INTEL_BASE="/usr/tce/packages/intel/${COMPILER_VERSION}"  # Update to your path
+
+MPI_IMPL="mvapich2"                               # Or openmpi, mpich, etc.
+MPI_VERSION="2.3.7"                               # Update to your MPI version
+MPI_COMPILER_VERSION="${MPI_IMPL}-${MPI_VERSION}"
+MPI_BASE="/usr/tce/packages/${MPI_IMPL}/${MPI_COMPILER_VERSION}-${COMPILER_VERSION}" # update to your path
+
+PYTHON_VERSION="3.12.2"                           # Update to your Python version
+PYTHON_BASE="/usr/apps/python-${PYTHON_VERSION}"  # Update to your path
+```
+
+**How to find your paths:**
+```bash
+# Find your compilers
+which icc      # Intel C compiler
+which icpc     # Intel C++ compiler
+which mpicc    # MPI C wrapper
+which mpicxx   # MPI C++ wrapper
+which python3  # Python executable
+
+# Get version information
+icc --version
+mpicc --version
+python3 --version
+```
+
+#### **CUDA GPU Configuration Example**
+```bash
+###########################################
+# Compiler Versions and Base Paths
+###########################################
+# Host Compiler
+CLANG_VERSION="ibm-14.0.5"                        # Update to your Clang version
+COMPILER_VERSION="clang-${CLANG_VERSION}"
+CLANG_BASE="/usr/tce/packages/clang/${COMPILER_VERSION}"
+
+# CUDA
+CUDA_VERSION="11.8.0"                             # Update to your CUDA version
+CUDA_BASE="/usr/tce/packages/cuda/cuda-${CUDA_VERSION}" # Update to your CUDA Path
+
+# MPI
+MPI_IMPL="spectrum-mpi"                           # Update to your MPI implementation / version / path
+MPI_VERSION="rolling-release"
+MPI_COMPILER_VERSION="${MPI_IMPL}-${MPI_VERSION}"
+MPI_BASE="/usr/tce/packages/${MPI_IMPL}/${MPI_COMPILER_VERSION}-${COMPILER_VERSION}"
+
+# Python
+PYTHON_VERSION="3.8.2" # Like stated earlier update to your version / path
+PYTHON_BASE="/usr/tce/packages/python/python-${PYTHON_VERSION}"
+```
+
+**How to find CUDA paths:**
+```bash
+# Find CUDA installation
+which nvcc
+nvcc --version
+
+# CUDA is typically at /usr/local/cuda or /usr/local/cuda-11.8
+echo $CUDA_HOME  # May already be set
+```
+
+#### **HIP/AMD GPU Configuration Example**
+```bash
+###########################################
+# Compiler Versions and Base Paths
+###########################################
+# ROCm Compiler
+# Update all of the below to your own relevant versions / paths / anything specific to your
+# system
+ROCM_VERSION="6.4.2" 
+ROCM_MAGIC_SUFFIX="magic"
+COMPILER_VERSION="rocmcc-${ROCM_VERSION}-${ROCM_MAGIC_SUFFIX}"
+ROCM_BASE="/usr/tce/packages/rocmcc/${COMPILER_VERSION}"
+
+# MPI - Cray MPICH
+MPI_IMPL="cray-mpich"
+MPI_VERSION="9.0.1"
+MPI_COMPILER_VERSION="${MPI_IMPL}-${MPI_VERSION}"
+MPI_BASE="/usr/tce/packages/${MPI_IMPL}/${MPI_COMPILER_VERSION}-${COMPILER_VERSION}"
+
+# Python
+PYTHON_VERSION="3.9.12"
+PYTHON_BASE="/usr/tce/packages/python/python-${PYTHON_VERSION}"
+```
+
+**How to find ROCm paths:**
+```bash
+# Find ROCm installation
+which amdclang
+which hipcc
+hipcc --version
+
+# ROCm is typically at /opt/rocm or /opt/rocm-6.4.2
+echo $ROCM_PATH  # May already be set
+```
+
+#### **macOS Configuration Example**
+```bash
+###########################################
+# User-Configurable Paths
+###########################################
+# Homebrew location
+HOMEBREW_PREFIX="${HOMEBREW_PREFIX:-/opt/homebrew}"  # or /usr/local for Intel Macs
+
+# System Clang (usually fine as-is)
+CLANG_BASE="/usr/bin"
+
+# MPI installation (REQUIRED: Update this!)
+MPI_BASE="${HOME}/local/bin"                      # Update to your MPI location
+# Common locations:
+#   Homebrew: /opt/homebrew/bin
+#   MacPorts: /opt/local/bin
+#   Anaconda: ${HOME}/anaconda3/bin
+
+# Python location (REQUIRED: Update this!)
+PYTHON_BASE="${HOME}/anaconda3/bin"               # Update to your Python location
+# Common locations:
+#   Homebrew: /opt/homebrew/bin
+#   System: /usr/bin
+```
+
+**How to find paths on macOS:**
+```bash
+# Check architecture
+uname -m  # arm64 for Apple Silicon, x86_64 for Intel
+
+# Find MPI (install if missing: brew install open-mpi)
+which mpicc
+which mpicxx
+
+# Find Python
+which python3
+python3 --version  # Should be 3.8 or newer
+
+# Check Homebrew prefix
+brew --prefix
+```
+
+### **Step 3: Update Module Commands (HPC Systems Only)**
+
+If you're on an HPC system with a module system, update the `module load` commands to match your system:
+```bash
+###########################################
+# Module Loading
+###########################################
+module load intel/2023.2.1-magic    # Update to match your system's modules
+module load CMake/3.26.3
+module load python/3.12
+module list
+```
+
+**How to find available modules:**
+```bash
+module avail          # List all available modules
+module avail intel    # Search for Intel modules
+module avail cuda     # Search for CUDA modules
+module list           # Show currently loaded modules
+```
+
+If your system doesn't use modules (like most macOS or personal Linux systems), you can comment out or remove the module commands.
+
+### **Step 4: Run the Install Script**
+
+Once you've customized the config file, run the appropriate install script from your build directory:
+```bash
+cd ../exaconstit_builds  # Or wherever you want to build
+../ExaConstit/scripts/install/unix_cpu_intel_install.sh  # Or appropriate script
+```
+
+The script will:
+1. Validate your configuration
+2. Display a build summary
+3. Download and build all dependencies
+4. Build ExaConstit
+5. Save detailed logs in each component's build directory
+
+**Expected build time:** 10 minutes to 45 minutes depending on system / parallelism / GPU builds or not.
+
+---
+
+## Advanced Configuration
+
+### **Updating Dependency Versions**
+
+All dependency versions are centralized in `common/dependency_versions.sh`:
+```bash
+# Edit version file
+code ExaConstit/scripts/install/common/dependency_versions.sh
+```
+```bash
+# Portability libraries
+export CAMP_VER="v2025.09.2"        # Update to newer version
+export RAJA_VER="v2025.09.1"
+export UMPIRE_VER="v2025.09.0"
+export CHAI_VER="v2025.09.1"
+
+# Material models
+export EXACMECH_REPO="https://github.com/LLNL/ExaCMech.git"
+export EXACMECH_BRANCH="develop"    # Change to different branch if needed
+
+# FEM infrastructure
+export HYPRE_VER="v2.32.0"          # Update to newer version
+export METIS_VER="5.1.0"
+
+export MFEM_REPO="https://github.com/rcarson3/mfem.git"
+export MFEM_BRANCH="exaconstit-smart-ptrs"  # Change branch if needed
+
+# Main application
+export EXACONSTIT_REPO="https://github.com/llnl/ExaConstit.git"
+export EXACONSTIT_BRANCH="the_great_refactoring"  # Change branch if needed
+
+# Build standards
+export CMAKE_CXX_STANDARD="17"
+export CMAKE_BUILD_TYPE="Release"
+```
+
+After updating versions, **all** build scripts will automatically use the new versions. No other changes needed.
+
+### **Changing GPU Architecture**
+
+Override the default GPU architecture at runtime:
+```bash
+# CUDA: Target Ampere A100 instead of default Volta V100
+CMAKE_GPU_ARCHITECTURES=80 ./unix_gpu_cuda_install.sh
+
+# HIP: Target MI250X instead of default MI300A
+CMAKE_GPU_ARCHITECTURES=gfx90a ./unix_gpu_hip_install.sh
+```
+
+Common GPU architectures:
+
+**NVIDIA CUDA:**
+- `60` - Pascal (P100)
+- `70` - Volta (V100)
+- `75` - Turing (RTX 20xx, T4)
+- `80` - Ampere (A100)
+- `86` - Ampere (RTX 30xx, A40)
+- `89` - Ada Lovelace (RTX 40xx, L40)
+- `90` - Hopper (H100)
+
+**AMD HIP:**
+- `gfx906` - MI50
+- `gfx908` - MI100
+- `gfx90a` - MI200 series (MI210, MI250)
+- `gfx940` - MI300X (compute-only)
+- `gfx942` - MI300A (APU)
+- `gfx942:xnack+` - MI300A with unified memory support
+
+### **Build Control Options**
+
+Control the build behavior with environment variables:
+```bash
+# Clean rebuild (removes all build directories and rebuilds from scratch)
+REBUILD=ON ./unix_gpu_hip_install.sh
+
+# Force submodule updates (syncs and updates all git submodules)
+SYNC_SUBMODULES=ON ./unix_gpu_cuda_install.sh
+
+# Adjust parallel build jobs (default is 4)
+MAKE_JOBS=16 ./unix_cpu_intel_install.sh
+
+# Combine multiple options
+REBUILD=ON MAKE_JOBS=8 CMAKE_GPU_ARCHITECTURES=80 ./unix_gpu_cuda_install.sh
+```
+
+**Available environment variables:**
+- `REBUILD` - `ON` to clean and rebuild, `OFF` to reuse existing builds (default: `OFF`)
+- `SYNC_SUBMODULES` - `ON` to force submodule sync, `OFF` to skip (default: `OFF`)
+- `MAKE_JOBS` - Number of parallel build jobs (default: `4`)
+- `CMAKE_GPU_ARCHITECTURES` - GPU architecture target (default varies by platform)
+- `MFEM_HIP_ARCHITECTURES` - MFEM-specific HIP arch (HIP only, default: `gfx942`)
+- `OPENMP_ON` - Enable OpenMP (default: `OFF`)
+- `ENABLE_TESTS_EXACONSTIT` - Build tests (default: `ON`)
+
+### **Using Different Repositories or Branches**
+
+To use a fork or different branch, edit `common/dependency_versions.sh`:
+```bash
+# Use your fork of MFEM
+export MFEM_REPO="https://github.com/YOUR_USERNAME/mfem.git"
+export MFEM_BRANCH="my-custom-feature"
+
+# Use development branch of ExaConstit
+export EXACONSTIT_BRANCH="develop"
+
+# Use a different ExaCMech repository
+export EXACMECH_REPO="https://github.com/YOUR_USERNAME/ExaCMech.git"
+export EXACMECH_BRANCH="custom-material-models"
+```
+
+To use a specific commit instead of a branch:
+```bash
+# The build scripts will clone the repo, then manually checkout the commit:
+cd mfem && git checkout abc123def456
+cd ../exaconstit_builds
+# Re-run the build script with REBUILD=ON
+```
+
+### **Custom Compiler Flags**
+
+You can add custom flags by editing the config file:
+```bash
+# In your config file (e.g., configs/gpu_cuda_config.sh)
+
+# Add optimization flags
+export CMAKE_CXX_FLAGS="-fPIC -std=c++17 --gcc-toolchain=${GCC_BASE} -O3 -march=native"
+
+# Add debugging symbols
+export CMAKE_CXX_FLAGS="${CMAKE_CXX_FLAGS} -g"
+
+# Add preprocessor definitions
+export CMAKE_CXX_FLAGS="${CMAKE_CXX_FLAGS} -DMY_CUSTOM_DEFINE"
+```
+
+---
+
+## Build Locations and Output
+
+By default, all builds install to your build directory:
+```
+your_build_directory/
+├── camp/
+│   ├── build_${BUILD_SUFFIX}/        # Build artifacts
+│   └── install_${BUILD_SUFFIX}/      # Installed library
+├── RAJA/
+│   ├── build_${BUILD_SUFFIX}/
+│   └── install_${BUILD_SUFFIX}/

+```
+
+Where `${BUILD_SUFFIX}` is:
+- `cpu` for CPU builds
+- `cuda` for CUDA/NVIDIA builds
+- `hip` for HIP/AMD builds
+
+### **Build Logs**
+
+Build logs are saved in each component's build directory with standardized names:
+- `my_<package>_config` - CMake configuration output
+- `my_<package>_build` - Compilation output
+- `my_<package>_install` - Installation output
+
+Example: To check why RAJA failed to build:
+```bash
+cd RAJA/build_cuda
+less my_raja_build  # View the build log
+```
+
+### **Disk Space Requirements**
+
+Typical disk space usage:
+- **CPU build**: ~1 GB total
+- **GPU build (CUDA/HIP)**: ~2 GB total
+  - Includes additional Umpire and CHAI libraries
+  - GPU architectures add to binary sizes
+
+---
+
+## Troubleshooting
+
+### **Configuration Issues**
+
+#### **"Module not found" errors**
+```
+ERROR: Unable to locate a modulefile for 'intel/2023.2.1-magic'
+```
+
+**Solution:**
+- Check available modules: `module avail intel`
+- Update the module version in your config file
+- If not using a module system, comment out the `module load` commands
+
+#### **"Compiler not found" errors**
+```
+CMake Error: CMAKE_C_COMPILER not found
+```
+
+**Solution:**
+- Verify the compiler path: `ls -la /path/to/compiler`
+- Check that the executable exists: `which icc` or `which clang`
+- Update the `*_BASE` variable in your config file
+- Ensure the compiler is in your `PATH`
+
+#### **"Python not found" errors**
+```
+Could NOT find Python3 (missing: Python3_EXECUTABLE)
+```
+
+**Solution:**
+- Verify Python installation: `which python3` or `which python`
+- Check Python version (must be 3.8+): `python3 --version`
+- Update `PYTHON_BASE` in your config file
+- If using Anaconda: `conda activate your_env` before building
+
+#### **MPI errors**
+```
+Could not find MPI compiler wrappers
+```
+
+**Solution:**
+- Verify MPI installation: `which mpicc && which mpicxx`
+- Update `MPI_BASE` in your config file
+- Test MPI: `mpicc --version`
+- On macOS, install with: `brew install open-mpi`
+
+### **Build Failures**
+
+#### **Out of memory during compilation**
+```
+c++: fatal error: Killed signal terminated program cc1plus
+```
+
+**Solution:**
+- Reduce parallel jobs: `MAKE_JOBS=2 ./unix_*_install.sh`
+- Close other applications
+- Add swap space if building on a resource-constrained system
+
+#### **Disk space errors**
+```
+No space left on device
+```
+
+**Solution:**
+- Check available space: `df -h .`
+- Clean previous builds: `REBUILD=ON ./unix_*_install.sh`
+- Build in a location with more space
+- Remove old build directories
+
+#### **Dependency build fails partway through**
+
+**Solution:**
+1. Check the specific log file in the failing component's build directory
+2. Common issues:
+   - Missing system libraries (install via package manager)
+   - Version incompatibilities (check `dependency_versions.sh`)
+   - Network issues during git clone (retry with `SYNC_SUBMODULES=ON`)
+3. Try a clean rebuild: `REBUILD=ON ./unix_*_install.sh`
+4. Build dependencies individually to isolate the issue
+
+#### **Git submodule errors**
+```
+fatal: unable to access 'https://github.com/...': Failed to connect
+```
+
+**Solution:**
+- Check network connectivity
+- If behind a firewall, configure git proxy
+- Clone repositories manually if needed
+- Force submodule sync: `SYNC_SUBMODULES=ON ./unix_*_install.sh`
+
+### **Platform-Specific Issues**
+
+#### **macOS: "xcrun: error: invalid active developer path"**
+
+**Solution:**
+```bash
+xcode-select --install
+```
+
+#### **macOS: Missing dependencies**
+
+**Solution:**
+```bash
+# Install Homebrew if not already installed
+/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
+
+# Install required tools
+brew install cmake
+brew install open-mpi
+brew install python3
+```
+
+#### **macOS: Architecture mismatch (Apple Silicon vs Intel)**
+
+**Solution:**
+- Ensure all dependencies are built for the same architecture
+- For Apple Silicon, use ARM-native tools: `arch -arm64 brew install ...`
+- For Intel compatibility on Apple Silicon: `arch -x86_64 brew install ...`
+
+#### **HPC: Module conflicts**
+
+**Solution:**
+```bash
+# Clear all modules and reload
+# Some HPC will automatically switch things for you
+# So only do this if your HPC center advises you to purge modules
+module purge
+module load intel/2023.2.1-magic
+module load cmake/3.26.3
+# ... load other required modules
+```
+
+#### **HPC: Quota exceeded**
+
+**Solution:**
+- Build in your scratch space instead of home directory
+- Clean old builds regularly
+- Check quota: `quota -s` or `lfs quota -h $HOME`
+
+### **GPU-Specific Issues**
+
+#### **CUDA: "nvcc not found"**
+
+**Solution:**
+- Verify CUDA installation: `which nvcc`
+- Update `CUDA_BASE` in `gpu_cuda_config.sh`
+- Load CUDA module if on HPC: `module load cuda`
+- Set `CUDA_HOME` environment variable
+
+#### **CUDA: Architecture mismatch**
+```
+nvcc fatal: Unsupported gpu architecture 'compute_XX'
+```
+
+**Solution:**
+- Check your GPU architecture: `nvidia-smi`
+- Update `CMAKE_GPU_ARCHITECTURES` to match your hardware
+- Common fix: `CMAKE_GPU_ARCHITECTURES=70 ./unix_gpu_cuda_install.sh`
+
+#### **HIP: "amdclang not found"**
+
+**Solution:**
+- Verify ROCm installation: `which amdclang`
+- Update `ROCM_BASE` in `gpu_hip_config.sh`
+- Load ROCm modules: `module load rocm`
+- Set `ROCM_PATH` environment variable
+
+#### **HIP: MI300A memory issues**
+
+**Solution:**
+- Set unified memory flag: `export HSA_XNACK=1`
+- Verify architecture: `CMAKE_GPU_ARCHITECTURES=gfx942:xnack+`
+- Check system: `rocminfo | grep xnack`
+
+### **Runtime Issues**
+
+#### **Segmentation fault on startup**
+
+**Possible causes:**
+1. Library path issues - Ensure `LD_LIBRARY_PATH` includes all dependency lib directories
+2. ABI incompatibility - Rebuild with consistent compiler versions
+3. Missing runtime dependencies - Check with `ldd` on the executable
+
+#### **MPI initialization failures**
+
+**Solution:**
+```bash
+# Test MPI installation
+mpirun -np 2 hostname
+
+# Verify MPI library paths
+ldd ExaConstit/build_*/mechanics_driver | grep mpi
+
+# Check module environment
+module list
+```

+## Manual Build (Advanced Users)
+
+If you prefer to build manually or need more control over the build process:
+
+### **Prerequisites**
+
+You'll need to manually build all dependencies first:
+1. **CAMP** (v2025.09.2)
+2. **RAJA** (v2025.09.1)
+3. **Umpire** (v2025.09.0) - GPU builds only
+4. **CHAI** (v2025.09.1) - GPU builds only
+5. **ExaCMech** (develop branch)
+6. **Hypre** (v2.32.0)
+7. **METIS** (5.1.0)
+8. **MFEM** (exaconstit-smart-ptrs branch)
+
+See `scripts/install/common/build_functions.sh` for the exact build commands and CMake options.
+
+### **Building ExaConstit**
+
+Once all dependencies are built:
+```bash
+# 1. Clone ExaConstit
+git clone https://github.com/LLNL/ExaConstit.git
+cd ExaConstit
+git checkout the_great_refactoring
+git submodule update --init --recursive
+
+# 2. Create build directory
+mkdir build && cd build
+
+# 3. Configure (CPU example)
+cmake .. \
+  -DCMAKE_CXX_COMPILER=mpicxx \
+  -DCMAKE_C_COMPILER=mpicc \
+  -DENABLE_TESTS=ON \
+  -DENABLE_OPENMP=OFF \
+  -DENABLE_FORTRAN=OFF \
+  -DPYTHON_EXECUTABLE=/usr/bin/python3 \
+  -DMFEM_DIR=${MFEM_INSTALL_DIR}/lib/cmake/mfem/ \
+  -DECMECH_DIR=${EXACMECH_INSTALL_DIR}/ \
+  -DSNLS_DIR=${EXACMECH_INSTALL_DIR}/ \
+  -DRAJA_DIR=${RAJA_INSTALL_DIR}/lib/cmake/raja/ \
+  -Dcamp_DIR=${CAMP_INSTALL_DIR}/lib/cmake/camp/ \
+  -DCMAKE_BUILD_TYPE=Release
+
+# 4. Build
+make -j $(nproc)
+
+# 5. Test
+ctest
+```
+
+### **GPU Build Options**
+
+For CUDA builds, add:
+```bash
+cmake .. \
+  ... (all the above options) ... \
+  -DCMAKE_CXX_COMPILER=${CUDA_ROOT}/bin/nvcc \
+  -DCMAKE_CUDA_COMPILER=${CUDA_ROOT}/bin/nvcc \
+  -DCMAKE_CUDA_HOST_COMPILER=${HOST_CXX_COMPILER} \
+  -DCMAKE_CUDA_ARCHITECTURES=80 \
+  -DENABLE_CUDA=ON \
+  -DFMT_DIR=${UMPIRE_INSTALL_DIR}/lib64/cmake/fmt \
+  -DUMPIRE_DIR=${UMPIRE_INSTALL_DIR}/lib64/cmake/umpire \
+  -DCHAI_DIR=${CHAI_INSTALL_DIR}/lib/cmake/chai
+```
+
+For HIP builds, add:
+```bash
+cmake .. \
+  ... (all the above options) ... \
+  -DCMAKE_CXX_COMPILER=${ROCM_ROOT}/bin/amdclang++ \
+  -DCMAKE_HIP_COMPILER=${ROCM_ROOT}/bin/amdclang++ \
+  -DCMAKE_HIP_ARCHITECTURES=gfx942 \
+  -DENABLE_HIP=ON \
+  -DFMT_DIR=${UMPIRE_INSTALL_DIR}/lib64/cmake/fmt \
+  -DUMPIRE_DIR=${UMPIRE_INSTALL_DIR}/lib64/cmake/umpire \
+  -DCHAI_DIR=${CHAI_INSTALL_DIR}/lib/cmake/chai
+```
+
+---
+
+## Next Steps
+
+After successful installation:
+
+- **Run the test suite**: `cd ExaConstit/build_*/` then `ctest` or `make test`
+- **Try example problems**: See `examples/` directory
+- **Read the documentation**: Check the `docs/` folder for detailed usage guides
+- **Join the community**: Open issues or discussions on GitHub
+
+For questions about using ExaConstit after installation, see the main [README](../README.md) and documentation in the `docs/` folder.
