I am still new in using Ansys fluent and trying to simulate a spinning golf ball with dimples to study its drag and lift coefficient when the size of dimple is manipulated. I have read some research stating that they imposed a rotating motion on the whole wall domain and the surface of the golf ball as well. One of the past I researched uses a spherical domain over their golf ball and imposing a rotational and translational motion simultaneously on the domain. The spherical domain does not have an inlet, they set the whole external surface as an outlet. How do I impose rotational and translational motion on a domain simultaneously? link to the research paper: https://www.researchgate.net/publica..._Smooth_Sphere
