Hello everyone,
I want to creat a swirl at the exit of a conduit. I am using Ansys Fluent.
The idea is to define a boundary condition (BC) at the exit of the conduit.
I don't know how to set the velocity to this BC. It requires a user-defined function (UDF) because Fluent does not provide the ability to vary the tangential velocity from the center to the end of the disk.
If someone could help me write this UDF.
Thank you very much!

-Flatten the end a little and twist it if possible
-Put a helix inside at the mouth
-Add a small deflecting vanes at the mouth.
The last is probably is easier to implement numerically.

Thank you Riadh Al Rabeh for your response.
Isn't there a way to introduce a UDF and set the boundary conditions at the exit ?
