[FLASH-USERS] Is the ​implicit magnetic diffusion solver can be used for axial magnetic field in FLASH4.7

[Ryan Farber]

Hi Eddie, since you mentioned active development, do you know if there's
any status update for FLASH 5.0? Or plans for FLASH 4.X to upgrade from
PARAMESH/Chombo to AMReX or other grids that can scale to leverage
new/upcoming exaflop machines?

Best,
--------
Ryan

When I look at the "Zpinch" simulation example, I find that the axial magnetic field is not initialized. This is weird because I believe the "Zpinch" case is actually an example of MagLIF experiment. It should have axial magnetic field.
