parabolic inlet velocity condition

Hi everyone,

I have a case that have parabolic velocity inlet condition. it changes according to radius distance from the center of the inlet surface. here I attached the profile. How can I define the velocity profile?

Based on your plot, the profile is not parabolic.

But you are lucky, the Fluent manual contains a UDF that practically does what you want. Did you already search there?

I could not find this example. Where is it?
