Hello,

I have tried to install OpenFOAM v9 in Ubuntu 20.04 LTS under WSL (windows 11).

I have followed the process:
https://openfoam.org/download/9-ubuntu/

Everything went ok. However, when I typed:

gedit ~/.bashrc

I have got the message:

Unable to init server: Could not connect: Connection refused

(gedit:22): Gtk-WARNING **: 12:09:05.965: cannot open display:

So, the installation could not be completed.

Please help.

Hi Mary,

Your installation is complete. This last step is just meant to load the OpenFOAM environment each time you start a new session, so you don't have to do it manually. Now if your just type the command below in your terminal, it should load the OpenFOAM environment and you will be good to go:

source /opt/openfoam9/etc/bashrc

But this solution is not very handy since you will have to do it each time you start a new session. This is why we usually add this line in a file named .bashrc in your home directory. This file is read every time you start a new session and it is used to load all kind of things to fit the user's preferences.

You get an error because gedit is a text editor with a GUI and you don't have a graphical environment in WSL.

There are 2 solutions: doing this last step without opening an editor needing a graphical environment or enabling graphical applications in WSL.

This link explains how to do both: https://openfoam.org/download/windows/


Cheers,
