open TELEMAC-MASCARET The mathematically superior suite of solvers

Hej there,

I try to find a running solution for my boundary conditions. Right now my model crashes, since I can not find a solution for the open boundaries east and west.

How can I fix this issue without setting this boundaries as solid walls, since this influences my model. I know one fix would to increase the size to east and west , but this would also increase the modeling time.

Thanks in advance
