Hi,
I am trying to give a boundary condition for v velocity by udf in fluent 15. The boundary I'm trying to give is suction and blowing type (i.e., it has both outward and inward velocity components). But when I implement it in fluent, it cancels my outward component of velocity (Maybe because I'm defining it in velocity inlet) and the only component is inlet to the boundary. Is there any way I can give both the components of velocity at the same boundary?

I have attached both pictures of how the v velocity should vary on my top boundary and how fluent is showing.

Please help, if you have knowledge about this issue.

This should be the function like

This is how it is coming in fluent

Please ignore the values in function. These were for different lengths, I am concerned about the suction part which is getting removed.
