Dear all,
I'm trying to run in parallel a case in foam extend 4.1 on ubuntu 18.04.
After decomposing the mesh (patchConstrained method) in 4 processors, I get the following error when running the case:

Create time

Create mesh for time = 0

MPI_ABORT was invoked on rank 2 in communicator MPI_COMM_WORLD
with errorcode 1.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.

What does this error mean? Is it something related to the mpi library?
Thanks,
