I want to use deforming/moving mesh function to solve this problem. how to write in the udf file about roation. who can tell me? thank you first.

Dear sir I have a problem with this title. If it's possible for you please send me your received responses. Very thanks for your attention to my request. With the best regards. Mahdi saniee nezhad

Please have a look at the dynamic mesh documentation. It has quite a few example UDFs for defining different kind of motions to rigid bodies.

If you don't have access to the documentation, please contact your FLUENT local office for the documentation.

Thanks,
