open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello,

I am running into this error when trying to adapt the border_ice tutorial to a real river:

I've tried various possible solutions related to similar errors I found on the forum, but nothing seems to work. When I add "ADVECTION OF TRACERS = false" to the steering file, the simulation runs and I see border ice growth, but the ice does not thicken no matter how long I let it run for.

Any advice would be great. I attached the case files for reference.

Hello,

There seems to be a problem in the hydraulic part.
I can take a look at your problem. Meanwhile, it works by running the case with the finite volume part, by adding in your t2d streering :

EQUATIONS = 'SAINT-VENANT FV'
VARIABLE TIME-STEP = YES
DESIRED COURANT NUMBER = 0.9

It is slower but still run the time I try to solve your issue.

Best regards,
Florent
