Moving Mesh
 

How Can i define the path for moving mesh? And can I give rotation to it?

As I want to simulate friction stir welding process, tool (heat source) is rotating as well as translating. So how to simulate this thing with Ansys?
i tried by giving the moving wall option to the tool, but while rotating it is not considering translating . So I am going for moving mesh method.

can anyone suggest me any method?
