[FLASH-USERS] Unsplit MHD Solver PPM problem

[Samuel Friedman]

Dear FLASH,

I'm running simulations with magnetized shocks and I wanted to try using 
the higher order solvers in the unsplit MHD solver.  FLASH3.3 includes a 
3rd order PPM solver.  I set up my problem in 2D Cartesian coordinates 
(using AMR) and the simulation crashes after about 60 timesteps.

I run the same simulation with the 2nd order MUSCL-Hancock solver and the 
simulation runs no problem.  I tried playing around with various flags, 
but nothing seemed to help.  Any ideas / suggestions?
