open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi,

I would like to do the sedimentation calculation with multi-grain classes in conflence area. I try to do that with the validation cases of Telemac2d and Sisyphe. I make use of the river confluence case in Telemac2d and river_arc case in Sisyphe. Based the two cases'steering files, I edit new steering files. When do the sediment calculation, at the beginning of the iteration, the information “MAX D'ITÉRATIONS ATTEINT” appears several times, and the calculation end normally. However, the results are null.
Why that happend? I submit my steering files and boundary file, could you give me some suggestions?

Thanks.

Dear Jinyong,
please find below some hints:
(1) run your hydrodynamics problem WITHOUT coupling sisyphe. See if your solution is stable and, if the case, if you reached your steady state.
(2) if everything is OK, you can couple sisyphe and run a test simulation with only one class of sediment
(3) only after steps (1) and (2) are OK, pass the your fully classes problem.

Take care of the time steps, etc.

I hope it helps,

Pablo
