SUBROUTINE ProblemBC(NodeInfo Info)

Defined In:

contrib/astro/problem.f90

Inputs:

NodeInfo Info. The grid has its boundary conditions adjusted.

Description:

Establishes axial symmetry for cell-centered magnetic fields (q(:,:,:,:,6:7)) along Info's reflecting grid boundaries. Essentially, ProblemBC() makes sure that any ghost cells along a reflecting boundary reflect what's happening on the other side of that boundary. Note that ProblemBC() does not do anything if the problem is non-cylindrical (icylindrical == 0) or non-MHD (lMHD == .FALSE.).

Also, this subroutine does not yet support 3D cylindrical problems.
