Hello,
im trying to ran an Openfoam simulation on multiple cores.
It worked on my system in the past. I didnt consciously changed anything
especially on mpi related things.
The only thing i have changed, i updated my Ubuntu version from 18.04 to
20.04.
As always i trying to execute the following line:
kai@Kai-Desktop:~/OpenFOAM/kai-7/run/tutorials_of/multiphase/interFoam/laminar/damBreak_stl_II/damBreak$
mpirun -np 4 interFoam -parallel
In the past, the simulation started and worked fine. But now this
massage will appear:

It looks like MPI_INIT failed for some reason; your parallel process is
likely to abort. There are many reasons that a parallel process can
fail during MPI_INIT; some of which are due to configuration or environment
problems. This failure appears to be an internal failure; here's some
additional information (which may only be relevant to an Open MPI
developer):
ompi_mpi_init: ompi_rte_init failed
--> Returned "(null)" (-43) instead of "Success" (0)

Primary job terminated normally, but 1 process returned
a non-zero exit code. Per user-direction, the job has been aborted.

mpirun detected that one or more processes exited with non-zero status,
thus causing
the job to be terminated. The first process to do so was:
Process name: [[32896,1],0]
Exit code: 1
--------------------------------------------------------------------------
I looked into the Systemmonitor, but i didnt have a process with this
name or number.
If i execute
mpirun --version
the consol replys this message:
mpirun (Open MPI) 4.0.3
Report bugs to http://www.open-mpi.org/community/help/
How can I solve this problem ?
Best regards
