Todo list for SystemBase requirementes #5
Description
What should SystemBase (and thus every physics model) provide?
- Access dry (not scaled/multiplied for transient case) Jacobian (Stiffness matrix in the linear case)
- Assemble weak form into temporary matrix? (Although it is assembled at every timestep anyways, so order of operations matters!)
- Access mass matrix
- Control input interface
- Modifiable at every timestep
- Set initial state
- State/solution at every timestep
