I am trying to use PyFoam on Windows 10 to postprocess my OpenFoam cases (I am running OpenFOAM on WSL and works perfectly)


I have installed PyFoam using pip

 C:\Users\giorgio.giorgiani>pip install PyFoam

Installing collected packages: PyFoam 

Successfully installed PyFoam-2023.7

However when I write on the terminal pyFoamVersion.py I get the following error:

 C:\Users\giorgio.giorgiani>pyFoamVersion.py

SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape

I think there is a problem in the global path definition in Hardcoded.py

def globalDirectory():
    """:return: the global directory"""
    return path.join("/etc",_pyFoamDirName)

which is causing the crash due to the backslash (..?..)

Does anybody have an idea?


Thanks in advance

I found the solution:

Hope this helps someone in the future

Is there anyone who have experience using pyFoam under Windows?
I cannot manage this thing to work. After solving the previous problem, now I am facing this:
