Fluent UDF and macros
 

Hey ,
I am trying to simulate flow for a 3D VAWT .
Have completed my solution for fixed rotation of blades and have created few initial conditions.
Now i need to change the rotation of my blade such that it is a function of the airflow encountered by the blade and it should vary at every time step.
conceptually i have understood how it would take place, but am not able to put it into fluent. please help me!!

Could you upload the UDF that you used for this ?
