Non-return valve

Duh500 · October 15, 2019, 16:21

Hi! I'm simulating a liquid sloshing inside a tank and I need to set a boundary condition that allows the flow to pass a wall in one direction, but can't flow in the opposite direction, to represent a non-return valve. I'm not simulating an actual valve as such, I just want to allow the fluid to flow into one direction and not allow backflow.
How can I model this boundary condition in Star-CCM+?
