I am trying to run a simulation of Lammps software in a cluster with Linux environment, however my simulation crashes returning the error below.

mpirun noticed that process rank 9 with PID 0 on node lesc exited on signal 11 (Segmentation fault).

I believe that this error should not be directly related to the software but rather with mpi.
Could anyone kindly give me any insight into this kind of error? I don't understand much about how mpi works.
