Parabolic Velocity Profile In 3 D Pipe FLow
 

I am simulating a pipe flow in which i want to give the fully developed velocity at inlet in 3-d. So Can you please guide me how to write UDF for this parabolic profile.

Thanks

An example is already provided in the Fluent tutorials

However you will have to modify it for 3D, but it shouldn't be so hard :)

Can you provide tutorial?

Google is your friend :) For example here is a tutorial how to setup parobolic velocity profile in 2D.

thanks very much...
