After following the Getting Started tutorial at https://openfoam.org/download/13-ubuntu/, paraFoam resulted in the following error.

I am using OpenFoam13 through WSL Ubuntu 22.04. How do I fix this?

Created temporary 'pitzDailySteady.OpenFOAM'
QStandardPaths: wrong permissions on runtime directory /run/user/1000/, 0755 instead of 0700

Loguru caught a signal: SIGSEGV

I figured out how to fix this, and it's just a newbie mistake.

To fix the error message

QStandardPaths: wrong permissions on runtime directory /run/user/1000/, 0755 instead of 0700

Add this at the end of the ~/.bashrc file

chmod 0700 /run/user/1000

The segmentation fault might be because Paraview is not configured or might not work inside WSL. I had to install Paraview for Windows 11 first from their official website, then I followed these steps to make the "Getting Started" tutorial at https://openfoam.org/download/13-ubuntu/ work.

1. After the blockMesh and paraFoam commands, create a new file with the same name as the current directory, with file extension ".foam". Using the Getting Started example, we can use

touch pitzDailySteady.foam

to create this file

2. Launch Paraview (Ubuntu) from outside WSL. It should automatically link with your WSL configuration.

3. Locate the ".foam" file you created earlier. From here, you can now use paraview's functions to visualize your results.
