open TELEMAC-MASCARET The mathematically superior suite of solvers

hi,


I'm trying to see the discharge behavior on a channel with 90 ° bifurcation, my boundary conditions are Q and H at the inlet and H at the outlet with a discharge curve at both outputs, but when running my program on telemac doesn't meets the condition of Qinlet= Qoutlet1 + Qoutlet2

Thanks

Hello

The problem is that you are applying 2 conditions at each boundary, which could be wrong.
Actually, depending on the regime of the flow, the code needs 0, 1 or 2 conditions;
for an inlet: if subritical: 1 condition (discharge or elevation)
if supercritical: 2 condition (discharge+elevation)
for an outlet: if subcritical : 1 condition (discharge or elevation)
if supercritical: 0 condition

with my best regards
