Implementation of vector potential formalism
 
Implementation of vector potential formalism
 
Quick summary:
 
 
* Implemented staggered vector potential formalism according to Etienne et al. 2012 and the IllinoisGRMHD code
 
* This is contained in the Zelmani branch vector_potential
 
* Essentially isolated, rewrote or modified relevant code parts from IllinoisGRMHD and included them into GRHydro
 
* Removed old (dead) vector potential parts in GRHydro and made several changes to GRHydro core routines to make it work with staggered Avec and Bvec fields
 
* Currently compiles and only works with the cxx files/version of GRHydro
 
* Added initial data routine to GRHydro_InitData to initialize magnetic field configurations for the staggered Avec and Bvec fields
 
 
Next steps:
 
* First test runs for debugging
 
* Modify GRHydro's reconstruction routines to also reconstruct staggered B and velocity fields for computation of RHS of staggered Avec evolution (currently using a modified routine from IllinoisGRMHD)
 
* Modification of GRHydro's reconstruction routines to be coordinated with Philipp's work on new staggered CT scheme, as similar infrastructure required
