      Can someone suggesthow to simulate in Ansys fluent a cyclist with his legs moving as he pedals. I found this beautiful example on youtube but it does not explain how the animation was imported and used in starccp+ :

      You can use an overset mesh for the legs and prescribe the motion using DEFINE_GRID_MOTION.
