I also tried -

This gives the output -

And then when I again try the command

 it is still giving me the error -

Hi,

You can try the following tutorials on installing OpenFOAM in Windows 10 via WSL. Please let us know if that fixed your issue.

You may also check other videos there to see how to open the case files in ParaView.

In the 2nd video, @6:33  It is giving me the error "No such file or directory"

Either you have missed any step or there must be some mistake in the commnd. Note that liux is case sensitive.

I re-tried. It only opens a blank notepad along with a dialogue box saying "The system cannot find the path specified." 
08-07-21, 8:43 p.m. AnushkaTilekar
Are you using the same windows terminal with the ohMyZsh theme or the ubuntu terminal?
08-07-21, 8:53 p.m. divyesh7
I downloaded the Windows terminal and then from the drop down arrow selected Ubuntu as shown in the video
08-07-21, 8:58 p.m. AnushkaTilekar
instead of "zshrc", use "bashrc" term.
08-07-21, 9:05 p.m. divyesh7
Still same error - only opens a blank notepad along with a dialogue box saying "The system cannot find the path specified."
08-07-21, 9:07 p.m. AnushkaTilekar
can you share screenshot of your terminal?
