[FLASH-USERS] Segmentation fault encountered in RadTrans Test Problems

[Reyes, Adam]

Hi Jianhui,

It can be helpful to include the full setup line that you’re using and if possible the log file generate by FLASH. I’m guessing that you’re using the same setup as provided in the users guide and running with 8(?) mpi ranks.

This problem only sets up with a single block so the additional processors wouldn’t have anything to do and that could be the problem, but I don’t think that should be a problem.

I would also double check that the version of mpi that you built hypre with matches what you use to compile flash.
