Default How to create a parabolic velocity profile
Posts: n/a
Hi All,

I am wandering how to create a parabolic velocity at the inlet for a circular pipe flow problem in "3D". I have tried to write a UDF code for that, but it wasn't successful, which only gave me one parabolic profile when look in side way and another in uniform velocity profile when look from the top.

Besides, is that any website that let people download UDF code to solve common problem like this one here?

Thank you very much for reading or answering!
