Hello,

I have install CS 7.2 on Ubuntu 22.04. I use the GUI of CS.

Convergence tool is not running during calculation. If I press the convergence tool button, nothing happens. I have follow Tjunction tutorial case.

How can I fix that?

Best regards

Hello,

You are not alone. I have the same problem. Looks like some tricky incompatibility with python 3.10 because it works well with python 3.6.5 even in Ubuntu 22.04.

By the way, in python 3.10 $cspath is set to $cs_root_dir/local/lib/python3.10/dist-packages rather than $cs_root_dir/lib/python3.10/site-packages. It's not the cause of this problem but still it's weird.

Hello,

I have check the pathes of python 3.10, in the file code_saturne_build.cfg, it is written:

pythondir: /usr/local/local/lib/python3.10/dist-packages
pkgpythondir: /usr/local/local/lib/python3.10/dist-packages/code_saturne
There is nothing wrong, the folders exist

Do I need to use python 3.6.5 insted ? How can I do that?

Best regards

Hello,

I checked and found the problem, which is due to some timer quantity expecting an integer and receiving a floating-point value in recent PyQt versions (I did not check whether Python or PyQt is the cause).

The fix is pushed to GitHub for the master and v7.2 branches. So if your 7.2 build is based on a git clone, simply update and rebuild. Otherwise, the fix is simple, so you can do edit it manually if you really need to: https://github.com/code-saturne/code_sa ... 46e4bef607

Hello,

The commit works for 7.2 in Ubuntu 22.04. By the way, 7.0 also has the same problem and modifying the python script manually solves the problem.

Hello,

Still not working for me.

I change the 2 files MainView.py located in
- Home/Code_Saturne/code_saturne-7.2.0/python/code_saturne/gui/trackcvg
- Home/code_saturne/7.2.0/code_saturne-7.2.0/arch/Linux_x86_64/local/lib/python3.10/dist-packages/code_saturne/gui/trackcvg

Maybe I need to rebuild something?

Hello,

It seems your installation is still using the old (non-corrected) code. Did you reinstall after patching the sources ?
