I hope all of you are doing well. I have to write udf program for my simulation on fluent. In my 3D model 2 airfoil of VAWT rotating in circular fluid domain. Can anyone help me please how can I write udf code.
Thank you so much

Hi. Can you explain your problem in more detail?

Also, instead of writing a UDF, you can use the sliding-mesh method to simulate rotation.
