5 months ago It seems you are trying to launch a windows program from within wsl which is not generally possible. If you have a Python environment in windows, you can install PyFluent and use it from there. Launching Fluent in windows and then connecting from PyFluent from wsl might work if the networking between windows and wsl can be established (I haven't tested this).

5 months ago Testing this locally, I was able to launch Fluent installed on Windows through WSL, and this seems to be a configuration that we could support in PyFluent.
I've changed this bug tracker to a feature request, as I think this would be better classified as a new feature, rather than a bug fix.
Edit: Launching Fluent in the current working directory of WSL (Fluent ends up using the \\wsl.localhost network path), one issue I've noticed so far is that some startup command line argument combinations don't seem to work properly and cause Fluent to fail to launch with a cx2420.exe error, need to investigate further. Other than that, can read/write files with no issues in the Windows file system.

PyMAPDL can launch and connect to MAPDL if given the executable path: https://mapdl.docs.pyansys.com/version/stable/getting_started/wsl.html#launch-mapdl-in-the-windows-host-os
This was implemented here: https://github.com/ansys/pymapdl/issues/2315
I hope it helps!
