Fluid-Structure Interaction with Clawpack
Settings in solver.in
- Recommended options for Clawpack together with Ghost-fluid method (GFM) to obtain an absolut robust and reliable method:
- MUSCL reconstruction in primitive variables: Method(2)>=4 or Method(2)=1 (first order)
- Dimensional splitting: Method(3)=-2
- Positivity preserving upwind scheme:
- Roe+HLL or HLL approximative Riemann solver
- VanLeer or Steger-Warming flux vector splitting
- Exact Riemann solver (not always available)
- Components that cannot be proven to be positivity preserving might also work in some cases:
- Characteristic Wave-by-wave reconstruction: Method(2)=2
- Multi-dimensional Wave Propagation Method: Method(3)=2 or 22
- Roe approximative Riemann solver in original form (without dynamic transition to HLL)
