Hi,
Some time ago I installed OpenFOAM 3.0.x on the cluster following the procedure:

https://openfoamwiki.net/index.php/I...CentOS_SL_RHEL

starting from step 5 which basically uses software in ThirdParty-3.0.x folder rather than SYSTEM for compilation including the use of gcc 4.8. I only set the OpenMPI as SYSTEM for which I loaded the module OpenMPI/1.6.5-GCC-4.8.2. However the cluster has been updated to a new platform (including the gcc version which is now 6.4) and therefore this openmpi version is no longer available on the new platform. So the easiest thing I thought is to load one of the newer available openmpi versions such as OpenMPI/1.8.4-GCC-6 though it is compiled with a higher version of gcc. I recompiled openfoam without any issues and I can run in solvers in parallel.
However I have been encountering problems with compiling and/or running CFDEM.

Initially I was getting the following error during compilation:

gcc: error: unrecognized command line option '--showme:compile'

which I resolved by using

export WM_MPLIB=SYSTEMOPENMPI

which resolved the issue, though during compilation I see many lines mentioning some issue with mpi,

could not open file ompi/mpi/cxx/ …

But at the end of log file it mentions compilation is completed.

However I can’t run the solvers. For example when running one of the tutorials, I get the following error:

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

I get same error when for the LIGGGHTS solver. I think the error is due to incompatibility between gccs 6.4 and 4.8. But why wouldn’t give error when compiling openfoam? is there an easy way to resolve this?

Thanks a lot for the help
