Mathia1510 New Member Mathia Join Date: Dec 2017 Posts: 7 Rep Power: 8	Hello, I am simulating a ogee weir spillway and the only thing I know is the water height. I want the water level to stay constant at the boundary inlet for my whole simulation. I have read countless posts on this forum about the problem of constant water level at the boundary but it seems like no one has managed to do solve it or maybe I am not reading where I should be, anyways. Does someone have some intel on how to do this? Is it possible to set the hydrostatic water pressure to constant and U to 0? I would really appreciate some help
