open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello,

I had a lot of problems with my model in the inlet boundary (because the slope is steep and the flow is almost supercritical). I fixed both flowarte and depth. I had a sediment equilibrium condition and the evolution of the ground seems to be wrong and cause the stop of my simulation.

I noticed that the numbers of iterations for the bedload discharge was limited at the value 10 although the default value for the maximum numbers of iterations for the solveur is 60 (NITMAX). The 10 iterations is reached very quickly.

Actualy, it seems there's a problem in the subroutines bedload_solvs_fe.f and bedload_evol.f where the number of iterations is taken from MAXADV instead of NITMAX. MAXADV is the numer of iterations for Advection Scheme...

Hope it helps

Regards

Increasing the maximum number of iterations rarely solves your problems (at least in my experiences). Steep slopes and almost supercritical conditions are at the far end (or behind) what is possible with Exner equation as it is implemented in Sisyphe...
Depending of what exactly your problem with evolution is, you could try to fix the bottom at the inflow boundary (e.g. first meters rigid bed only 10 cm below ZF)
