hydrostatic pressure boundary problem

I am simulating a open channel flow with wave coundary condition. I set the out let bc as a hydrostatic BC, which is defined as p=rou*g*h (CFX expression as: waterDen*g*(waterD-y) where waterD is the water depth and the waterDen is the water density) but since the free surface in the channel is moving up and down, the water depth is changing according to the wave profile as a function of time. How can I define the waterD correctly and avoid back flow?
Thanks! |
