open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello everybody!

I want to run a sediment transport simulation (internal coupling) with rigid bed (in the whole grid erodable bed = 0.8 m exept in a domain near to outflow boundary 3, there the erodable bed is 0 m).
With help of older forum posts, I managed preparing the rigid bed by inserting the variable "NOER" in the geometry file and modifying the subroutine "NOEROD".
In the liquid boundary file of Telemac2D there are 4 boundaries defined (1, 2, 4 with prescribed flowrates and 3 with prescribed elevation).
There should be no sediment entry (boundary 4) into the system and no export at boundaries 1&2, but evolution in the whole system. I'm not quite sure if I set the right settings for that in the Sisyphe steering file.

The problem is that although Telemac is running, but providing in the sisyphe results file "EVOLUTION=0" at every node.

I hope that somebody can give me a hint! I attached both steering files and the boundary conditions file.
Thanks in advance,
Katharina

Hi Catherine,

You will have to reduce the values given for the sediment sizes, as SISYPHE they are given in metres, not mm.
