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
