hello everyone

I am studying an open channel with an obstacle and I want to set boundary condition on the upstream(debit condition and not velocity condition cause the height of the water can vary) and downstream (water height condition and a constant debit) but I don't know how.

tanks

So I have used this test, the b.c are as below: 1) inlet boundary condition is set to velocity (v=q/h) if you rvel is not defined so you can use pressure inlet using hydrostatic profile. 2) for your out let use out flow condition if your out let does not have a difined profile.. goood luck
