Thanks Rob! For the revolution, is there an UDF in Fluent can define the path(I can obtain the function of ellipse)?

I have an idea about the elliptical motion, but I am not sure it will work, the thing is: I obtain the velocity function in X, Y, Z directions, and put these three functions in the “CG_MOTION” to realize this motion. But this method is a little bit complex. The ideal method in my mind is to define the expected path by input the ellipse function, and drive the object by the revolution speed, but I do not know if it is possible to realize.
