openfoam conda

A possibility to install OpenFOAM without admin rights is conda:

https://github.com/HenningScheufler/conda-openfoam

The installation process would be quite straightforward. Download and install the miniconda then run following commands:

conda create -n openfoam # create new env named openfoam 
conda activate openfoam # activate the enviroment
conda install openfoam -c conda-forge # download and install openfoam from conda forge

This could simplify the installation on workstations. For HPC spack is probably the better option
