dynamic mesh / boundary profile
 

Hi

I want to simulate an unstady 2-d motion of a ball (circle) inside a water. I want to give the ball a constant speed and solve the flow around it utilizing dynamic mesh capability of fluent. And I also want to use boundary profile (Give the ball constant speed) rather than the udf file. I have tried it but the ball does not move. I dont know wat is my fault.My file is simple just give the coordinates of wall of ball and velocity of them. But it does not work.Give me your advice.
