open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi,

I'm working on a combined-sewer trunk where the sedimentation causes many problems. A gate valve has been embedded in a collector of 1100m to create flushes. In order to evaluate the efficiency of the gate and predict the dynamics of the solids due to this gate, we want to simulate the hydrodynamic and sediment transport processes (bedload & suspended load). At first, I want to simulate with the 2D.
So I would be grateful if I have your helps about the way of creating such geometries and meshes. How can I provide the bathimetry for this "channel".

Knowing that the sewer collector section has an ovoid form about 3m of height and 2m of weidth. During the flush by the gate, the water level gets to maximum about 2m near the gate, so we have a open surface flow.


Thanks in advance,

Best Regards

Hi

You cannot represent a close pipe in a mesh.
Your only option is to create a mesh of the bottom part of your ovoid with a channel of 2 m width and give the right elevation to represent the ovoid.

hope this helps
