Hi @BenjaminRodenberg, Thank you for the response. I tried to do this, but finally I have to couple FEniCS with OpenFOAM, which is running directly on my system. So, it appears that they cannot communicate with each other. In my group, we use FEniCS with Anaconda also. Will coupling Fenics in a conda environment happen with OpenFOAM running directly or it will also have the same problem?
