The motion of the cylinder is as follows: 1. at t=0 the flow starts 2. at t=Ta the cylinder stars to rotate in anti clockwise direction with velocity VA 3. at t=Tx the cylinder stops rotating 4. at t=Tb the cylinder stars to rotate in clockwise direction with velocity VB 5. at t=Ty the cylinder stops rotating but the flows continues to flow over the cylinder. It would be really helpful to me, if anyone could give me an UDF for this or help me how to model it?
