Segmentation fault

Hello REEF3D team
When I run the program using the mpirun it shows this error

mpirun noticed that process rank 8 with PID 0 on node exited on signal 11 (segmentation fault)

can anyone please help how to resolve this issue?

If you get seg fault on running divemesh, probably you have out of RAM.

If you get seg fault on running reef3d,
- there could a version mismatch between reef3d and DM,
-improper compilation,
-something wrong in the grid setup,
-some wrong command in ctrl
-run out of RAM
