Boundary Conditions

Sas

I want to simulate the flow of water in a tank. Suppose the one side of the tank is open at upstream end and the water is coming in from this side. The same quantity of water is going out from the correspoding downstream end keeping the water level constant. Of course, the bottom boundary will be non slip wall boundary conditions (BC) where all the velocity componants are zero. Near side wall and far side wall BCs will also be same as the bottom. The BCs on top of the water surface will be slip wall type. What about the boundary condition on upstream side wall and downstream side wall? Thank you in adavance... Sas..
