open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello,
I carried out the simulation of bedload transport and I managed to obtain results.
When I try to simulate also the suspension transport it gives me the following error:
CVTRVF: 200 SUB-ITERATIONS REQUIRED FOR THE
DISTRIBUTIVE SCHEME. DECREASE THE TIME-STEP

PLANTE: PROGRAM STOPPED AFTER AN ERROR
RETURNING EXIT CODE: 2

|~~~~~~~~~~~~~~~~~~
|STOP 1

i attach the files used for the simulation
Can anyone help me ?
Thanks

It looks like the wave boundary conditions are causing a shock wave on the boundary. On the first time step there are large wave forces acting on the water column on the boundary nodes, but none on the interior nodes. You will have to ramp up the wave boundary conditions, or create an initial condition file.
