1- Running a solver under foam-extend 4.0 on Ubuntu 18.04 returns this error:

mpirun -np <N> <solver> -parallel
--------------------------------------------------------------------------
It looks like opal_init failed for some reason; your parallel process is
likely to abort.  There are many reasons that a parallel process can
fail during opal_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):

  opal_shmem_base_select failed
  --> Returned value -1 instead of OPAL_SUCCESS
--------------------------------------------------------------------------

2- I tried to change this line in <foam installation dir>/etc/bashrc:

# WM_MPLIB = SYSTEMOPENMPI | OPENMPI | MPICH | MPICH-GM | HPMPI | GAMMA | MPI | QSMPI | MVAPICH2
: ${WM_MPLIB:=OPENMPI}; export WM_MPLIB

to

# WM_MPLIB = SYSTEMOPENMPI | OPENMPI | MPICH | MPICH-GM | HPMPI | GAMMA | MPI | QSMPI | MVAPICH2
: ${WM_MPLIB:=SYSTEMOPENMPI}; export WM_MPLIB

and then re-compiled. It makes the whole of the openFoam corrupted, because, after this change, blockMesh even was not known to terminal with this error

error while loading shared libraries: libmpi.so.1

3- I recompiled foam by the script Allwmake.firstInstall; everything went smoothly. However it showed this:

Note: ignore spurious warnings about missing mpicxx.h headers

4- The problem still persists!

What do you think can help? Does re-cloning from github and re-installing help?

I recently had a bunch of problems installing Foam-Extend 4.0. Eventually, adding this line to my ~/.bashrc file fixed them.


export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib64/mpi/gcc/openmpi/lib64/

Hi courant_numero_uno,
Can you mention what does this directory include? Can you post 'ls' command output?
I don't have this directory. The most similar one is

/usr/lib/x86_64-linux-gnu/openmpi/lib

and its contents are:

libmca_common_libfabric.so           libompitrace.so.20.10.0
libmca_common_libfabric.so.20.10.0   libopen-pal.so
libmca_common_sm.so                  libopen-pal.so.20.10.1
libmca_common_sm.so.20.10.1          libopen-rte.so
libmca_common_verbs.so               libopen-rte.so.20.10.1
libmca_common_verbs.so.20.10.0       liboshmem.so
libmpi_cxx.so                        liboshmem.so.20.10.1
libmpi_cxx.so.20.10.0                mpi_ext.mod
libmpi_java.so                       mpi_f08_callbacks.mod
libmpi_java.so.20.10.0               mpi_f08_ext.mod
libmpi_mpifh.so                      mpi_f08_interfaces_callbacks.mod
libmpi_mpifh.so.20.11.0              mpi_f08_interfaces.mod
libmpi.so                            mpi_f08.mod
libmpi.so.20.10.1                    mpi_f08_types.mod
libmpi_usempif08.so                  mpi.mod
libmpi_usempif08.so.20.10.0          openmpi
libmpi_usempi_ignore_tkr.so          pkgconfig
libmpi_usempi_ignore_tkr.so.20.10.0  pmpi_f08_interfaces.mod
libompitrace.so

but doing export using this path at the end of ~/.bashrc did not solve the problem!

I also went thru these steps:

1- The method mentioned here; The problem was not solved.

2- The first method mentioned here; The problem was not solved.

3- In the directory of

/home/lian/foam/foam-extend-4.0/ThirdParty

I added the following line to AllClean.stage2

uninstallPackage openmpi-1.8.8 $1

Then I executed :

./AllClean.stage2
./AllMake.stage2

And the problem persists!

4- I tried to do this solution. But, there is this problem regarding foam-extend-4.0

5- I did not understand the 2nd method that @wyldckat has mentioned here.

to ...

Solution:
Using 'tar -c' command on my laptop where I had compiled foam extend before, I generated a compressed version of foam-extend 4.0 (Here is more information to do it). Then, using ' tar -x ' I extracted it on a node.
I did so in order to save time of re-compiling. But, actually it was the origin of the problem. I just removed and re-compiled foam-extend 4.0 and after that, it works fine.
