Outlet Boundary Condition

karananand · March 22, 2010, 21:21

Hi,
I am trying to simulate a simple 2D flow over an obstacle with one inlet and one outlet. The flow is laminar and incompressible. I need to specify an outlet boundary condition of v =0 ( velocity in the y direction should be zero) in FLUENT.
How to I specify the boundary conditions at the outlet ?

Hi
why do u need to impose such condition???????
i dont think at that u need it
Anyway i think that u can do it by putting a velocity inlet (but u can impose only a constant profile, or u must use UDF's i think)
