Default desired velocity profile from fan boundary condition

Hello everyone!

i am trying to develop a desired velocity profile from UDF using fan BC, but unfortunately i am not getting it.
I am attaching a pic which explains the problem as that the edge in the mesh is the fan.
A flow will start from the velocity inlet (left) and will pass through and over the fan BC edge where i have hooked a UDF for profile specification of pressure-jump. But even doing this i am not getting the desired profile.

Kindly Help urgently!

Regards and Thank you!

Could you provide your UDF and the equation that describes the fan boundary condition?
