Hello everyone!

I have the following problem:

I am modelling a transient problem about a VAWT (Vertical Axis Wind Turbine).

I have a beam which turns around the vertical axis. Over this beam I have 3 wings which also turns around. But I don`t want they to turn at a fixed RPM. They must be in a fixed angle in each quadrant.

I would like you to orient me about how to build my UDF.

-How can I do for Fluent to recognize the "beam rotation angle" variable?

-I have seen that I can use CG Motion to define velocities but I want to define positions. Is it possible? Or do I need to use velocities to do it?

-Is it possible to work with profiles? By the moment the profile I used works badly.

Thank you very much for your help
