Start of SplashFOAM

[Formula78]

Hi,
First thank you for the GUI!
I can't start SplashFOAM in the current Standard-release branch. I installed all necessary packages, but starting the programme with $python3 SplashFOAM.py appears:

    Traceback (most recent call last):
      File "/SplashFOAM/Source/SplashFOAM.py", line 2132, in <module>
        root = tk.Tk()
      File "/usr/lib/python3.10/tkinter/__init__.py", line 2299, in __init__
        self.tk = _tkinter.create(screenName, baseName, className, interactive, wantobjects, useTk, sync, use)
    _tkinter.TclError: couldn't connect to display "localhost:0"

Do you have any solution for this problem?

Hi @Formula78

Thanks for the feedback! Seems your x11 is not set properly. Please try the instructions in this post and let me know if it fixes the issue.

the command "export DISPLAY=:0" fixed it for me
