FSI 3D Upgrade

- Mesh conversion process
This page follows on from the standard FSI installation instructions. Follow those instructions first before continuing with this page.
Modify the adapter for 3D FSI
Download all the files for the 3D version from this Drive folder [todo add link]
Locate this installation location of the FEniCS-preCICE using python3 -m pip show fenicsprecice
Navigate to this location, in my case: cd /home/nik/.local/lib/python3.8/site-packages/fenicsprecice
Replace each file in your installation location with the 3D version you downloaded earlier.
Verify everything is working correctly
Download this modified tutorial case [todo add link]
Navigate to the solid-fenics folder and do ./run.sh - there should be no errors, and the output should pause after a short setup period.
Now open another Ubuntu terminal, and navigate to the fluid-openfoam folder and do ./run.sh
Both terminals should now have command outputs flying, similar to the original 2D tutorial case you ran when installing the 2D FSI software.
After a while, both terminals should stop. View the results in ParaView, and verify it looks similar to the original 2D tutorial case.
Install mesh conversion software
FEniCS sadly does not natively support the import of ANSYS or OpenFOAM meshes, so a workaround must be used.
python3 -m pip install meshio
