Ring-average method to treat singularity at a polar axis. More...

Detailed Description

Implement the ring-average technique by Zhang et al. (2019) JCP, to remove the severe time step restriction for multi-dimensional curvilinear finite-volume MHD solvers near a polar axis. The Ring Average technique is implemented as a post-processing step and thus requires no changes to the existing data structure, grid definition or numerical methods in the original MHD solver.
