WSL - ImportError: libmpi.so.40: cannot open shared object file: No such file or directory

[fmamitrotta]

Hi all, thanks for the great work on this open source repository!

I just want to flag that there could be something broken in the installation of openmpi.

I'm working on Windows Subsystem for Linux (WSL), using the following release:

PRETTY_NAME="Ubuntu 22.04.3 LTS"
NAME="Ubuntu"
VERSION_ID="22.04"
VERSION="22.04.3 LTS (Jammy Jellyfish)"
VERSION_CODENAME=jammy
ID=ubuntu
ID_LIKE=debian
HOME_URL="https://www.ubuntu.com/"
SUPPORT_URL="https://help.ubuntu.com/"
BUG_REPORT_URL="https://bugs.launchpad.net/ubuntu/"
PRIVACY_POLICY_URL="https://www.ubuntu.com/legal/terms-and-policies/privacy-policy"
UBUNTU_CODENAME=jammy

I've created a new anaconda environment and installed funtofem following the indications on the repository homepage:

conda create -n F2F python=3.9
conda activate F2F
conda install -c conda-forge -c smdogroup funtofem

Then I've tried to run sphere_transfer.py and got the following error when trying to import mpi4py:

ImportError: libmpi.so.40: cannot open shared object file: No such file or directory

I managed to fix this by running the following command as indicated at this page:

conda install openmpi openmpi-mpicc openmpi-mpicxx openmpi-mpifort

Not sure whether this is specific to WSL, just wanted to flag it in case there might be something wrong in the dependecies of funtofem.
