Hello everyone, REEF3D team

I am a student at Rovira i Virgili University, and I am modeling a concrete channel with sediment transport. I have a problem because the sediment accumulates at the outflow boundary. Is it possible to please help me find the problem? I am sending the support files and two images that illustrate the problem, showing the sediment at the beginning of the simulation and at the time end. I used 23.12 version.

Thank you

For cases like this, I would recommend using a relaxation zone for topo (see S 73).
