Scientific Goals
Random bits and pieces
- Reuse parts of Harm3D
Conventions / Variable names ect.
- Principally follow the Valencia formulation as out-lined in Anton et al. (2006)
- HydroBase's Bvec[1-3] GF will be identified with Valencia's B^i vector
- Bvec[] will be used both as an evolved quantity and a primitive variable
- Introduce "densitized_state" as a scalar that controls interpretation of Bvec[]'s meaning;
- if( densitized_state) then Bvec[] = B^i \sqrt(\gamma) else Bvec[] = B^i
- Only use locally calculated "comoving magnetic tensor" b^a when needed
