[wanis]

Hello Dear,

I need to write UDF to change angle of attack for a 3D wing which is a part of my work, which macro is convenient for this?? Is it Zone_motion or CG_motion?? really I need your help

furthermore, there are a zone one for the wing and already there is interface between the domain and the wing, so how I can build up the udf depends on motion as rotational wings and as rigid body to move with the other part through air in the duct.
I am using Fluent 16.1
Thank you in advance
