[FLASH-USERS] An error in running Sedov problem

[shuang liu]

Hi, all,
I'm getting started with the FLASH code with running the example Sedov
problem. When I issued './flash4' in the command lined, it seemed okay.
However, when I tried to run the problem with parallel settings 'mpirun -np
8 flash4', an error is reported:

Do you know what the problem is?
