Code design

• BoundaryCondition
  • Enums and implementations for velocity conditions
• DenseLinearAlgebra
  • Per-thread batched linear algebra (e.g. BLAS/LAPACK)
• Mesh
  • Cajita mesh management
• ParticleInit
  • User-defined functors initialize particles in a Cabana::AoSoA
• ProblemManager
  • Manages all problem data including grid fields and particles
  • Provides key abstractions to give meaning to templates
• Solver
  • Sets up the problem and manages devices (e.g. using GPUs vs. CPUs)
• TimeIntegrator
  • The core physics kernels
• VelocityInterpolation
  • Custom P2G/G2P operators for APIC
