Hi, I am new to OpenFOAM and now runnig a two-phase flow case parallelly. But it doesn't work and returns the following errors. I am not sure where it is wrong and it seems the OpenMPI is not installed correctly?

The OpenFOAM-6 is what I use and OpenMPI-3.1.2 was installed before installing OpenFOAM on my Ubuntu.

Thank you!

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

ompi_mpi_init: ompi_rte_init failed
--> Returned "(null)" (-43) instead of "Success" (0)
*** An error occurred in MPI_Init_thread
*** on a NULL communicator
*** MPI_ERRORS_ARE_FATAL (processes in this communicator will now abort,
*** and potentially your MPI job)
[Lancelot-Ubuntu:8226] Local abort before MPI_INIT completed completed successfully, but am not able to aggregate error messages, and not able to guarantee that all other processes were killed!
Primary job terminated normally, but 1 process returned
a non-zero exit code. Per user-direction, the job has been aborted.

can you post your commad lines?
how do you decompose your case?
how do you start your solver for decomposed case?
does the solver run without decomposition?
