[foam-extend.org] FE-4.0 and FE-4.1 : missing libmpi.so.40

lcliu · November 25, 2020, 05:05

I am installing FE-4.0 and 4.1 on my CENTOS 7.5, the process looks ok but it shows “error while loading shared libraries: libmpi.so.40: cannot open shared object files: No such file or directory” when I try to run tutorial case (for blockMesh and steadyCompressibleFoam).

I have openFoam v.2006 successfully installed on the same machine with openmpi 4.0.3, could any one share some experience upon this? Thanks in advance.

Hi,

What is the variable $WM_MPLIB set to? Is it the same for both the FE and OF-v2006?

Cheers,
Antimony

Thank you for the reply, the issue was resolved by adding the following line into my .bashrc:

export LD_LIBRARY_PATH=/PATH_TO_openmpi-version/lib:$LD_LIBRARY_PATH
