Hello Community,

I simulate a river with Telemac2d. My software was working but for my last simulation , I had this error (see below)
@STREAMLINE::SCARACT: THE NUMBER OF TRACEBACK INTERFACE CROSSINGS IGEN > 99application called MPI_Abort(MPI_COMM_WORLD, 2) - process 4.[/b]

After searching in the forum (www.opentelemac.org/index.php/assistance...rface-crossings-igen), I saw I could change the number 99 to 999. Hence, I change the value 99 to 999 in the streamline. f file (sources\utils\bief\streamline.f) .Then I run my simulation, but it didn’t work. I changed back the value from 999 to 99 and I performed the simulation again. Now I have this error:

[22152:0212/104142.730:ERROR:gpu_init.cc(481)] Passthrough is not supported, GL is disabled, ANGLE is

Also as soon as I launch my simulation, the executable telemac2d.py opens in my screen with Visual Studio Code. I don't understand what is going on.
Have you encountered such a problem?

Please find attached the picture of the error I have and the telemac2d.py file which popped up in my screen.

Thank you for your help

c.coulet OFFLINE Moderator Posts: 3722 Thank you received: 1031	About the problem with IGEN > 99 event the solution to increase the limit could work, it's also advised to look carefully to the model as there is probably an instability with exist near an interface to two subdomains. Try to understand why instability exists at this location and this will probably solve the parallel problem Regards

Carole OFFLINE Fresh Boarder Posts: 10	Hello, It is fine, I mange to associate telemac2d.py with Python. I will look for the instabillity. However , can you confirme that the IGEN > 99 change is done in the file streamline.f in the bief folder ?
