open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello everybody,
I am modelling a river in Telemac3d. I am prescribing water discharge upstream and elevation at the estuary.
I would like water to flow just in the main channel (the one with the more refined mesh in the picture) but instaed water goes everywhere in my domain. I tried with giving boundaries to the whole sides of the domain and also restricted to the refined mesh zone (as in the picture) but I can't solve the problem.
Can anybody help me?
Thank you a lot
Giulia

Hi
The configuration seems ok but what about the bottom and the initial condition?
Regards

Hey! Thank you for your reply. I think the issue is with initial condition, I am now trying other attempts and I hope to solve this!
