This may be a unique issue, but in hopes to help someone else, here is a summary of my problem... with a solution !

My config:
OpenSUSE Tumbleweed VERSION="20230110" on WSL2 (Linux kernel version 5.10.16.3-microsoft-standard-WSL2)


Upon installing OpenFOAM2212 from the OpenSUSE package repository, I was unable to run blockMesh or icoFoam; receiving the message,

"error while loading shared libraries: libmpi.so.12: cannot open shared object file: No such file or directory"


I ensured that openmpi and openmpi-libs were installed but was still not able to "find" these files.


What needed to be done:
1. Make sure openmpi1-libs was installed
2. Add to $LD_LIBRARY_PATH /usr/lib64/mpi/gcc/openmpi1/lib64/
- YMMV with other configs and distros. You can see the lib file locations with rpm -ql openmpi1-libs on OpenSUSE to make sure you are adding the right location to the aforementioned LD_LIBRARY_PATH variable. Incidentally, debian (Ubuntu) distros can use dpkg to see the same info.
