After installation of WSL and Ubuntu, the next step is to install and configure OpenFoam. A few steps may be optional if you have already gone through.
Step 1. From the OpenFoam wiki
# Add the repository
curl -s https://dl.openfoam.com/add-debian-repo.sh | sudo bash
# Update the repository information
sudo apt-get update
# Install preferred package
sudo apt-get install openfoam2512-default
# verify by the command echo $PATH
Step 3. Copy tutorials to run folder
# Source /usr/lib/openfoam/openfoam2512
# Destination /home/tiger/OpenFOAM/tiger-v2512/run
Lessons learned
1. The default login was root
2. During reinstall from MS Store, new user was created
3. Included cd command at the end (~$ nano ~/.bashrc) for /home/tiger as working directory
4. Need to create the run and preceding directory structure as mentioned in the $PATH
