Hi, I have installed PyFoam version 2021.6 using pip on Ubuntu 20.04.4 LTS.

The only wrinkle I encountered so far was that my system installed the scripts at $HOME/.local/bin instead of /usr/local/bin. I solved this by adding it to my path in ~/.bashrc.

It recognizes OpenFOAM v8 when I run pyFoamVersion.py

I copied the tutorial case $FOAM_TUTORIALS/incompressible/icoFoam/cavity/cavity into $HOME, constructed the mesh, and ran icoFoam to confirm the case was setup properly.

Then I executed:

username@DESKTOP-7R3L17E:~/cavity$ pyFoamPlotRunner.py --clear --progress --auto auto
Clearing out old timesteps ....
