Open Channel Downstream Depth BC
 

Hello!


It is possible to set a depth as a boundary condition in downstream in openfoam? I tryied to set a p_rgh as fixedValue or fixedFluxPressure with the heigth value in the outlet but the solver not converge.


And, there are a correct way to set a BC inlet depth? I trying to use a inlet with de exactly area and then setting the flowrate or setting the velocity and the flowrate and hoping the solver calcule the correct depth, but I dont know if this last way works. What you recommended?


Thanks!
