open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi,

I have created a mesh for a floodplain, divided in two parts:
- a channel submesh for the river bed, created with the T3 Channel Mesher
- a main mesh, including the channel submesh, created with the T3 Mesh Generator.

Here you can see the result :


I was wondering if the junction between the two meshes is normal. I have noted that in Fudaa it creates issues, even sometimes it creates solid boundaries at the junction.

I think this is coming from the difference with the mesh's density but maybe there is a way to solve this situation ?

Any answer would be appreciated ! Thanks

Have a good day

Hi
Without anymore information, it's difficult to answer.

Did you define some density criteria around the submesh? in the T3 mesh generator?
If yes, the density should be more or less similar to the channel mesher distance along the river...

Regards
