I want to give tangential velocity input to wall of circle. Every face have different velocity input value according to its angle from center of origin. How can I write udf for that. I did not find any example of it. I don't know how to find location of face on the circle edge. Appreciate for all your help

pakk will become famous soon enough
Did you find the example for parabolic profile?

It shows how to get location of a face.

The rest is just mathematics...

How do I create a function in the udf? I have to use legendre polynomials and associated legendre functions
