Hi

Do we have Reference frame with Translation movement/motion.

I am trying to simulate a vehicle/Train movement on a plane with Air domain around it.

    Probably the closest thing would be to apply a wall velocity to the moving surfaces.  It won't be as accurate as actually moving the mesh (wake capturing probably won't be the same), but it might be a start.  I've attached a short recording from HWCFD.
