Current Status
- MHD implemented in "parallel" to non-MHD code in GRHydro
- Variables:
- HydroBase: primitives
- GRHydro: conservatives
- GRHydro: Calculate magnetic pressure in calculation of Tmunu, and store it
- Riemann: only HLLE and local Lax-Friedrich, no Roe, no Marquina (Bruno: HLLE)
- HLLC or HLLD should be better than HLLE
- Con2Prim
- works for polytropic cases
- all NR-based, only choice of variables
- Multiple guesses sometime necessary: should be "supported"
- Bruno: divergence cleaning worked smoothly until merger
- Putting everything in source-terms doesn't work well
