Dynamic Mesh - Ball in Cylinder

Hamish

I am trying to learn more about the dynamic meshes in fluent, and have what I think should be an easy model to setup. I created and meshed a cylinder with sphere cut out of it, and created a zone at the sphere. I am confused what to do in the dynamic zone form under Motion UDF/Profile. I want to just have the ball move at a constant velocity for a given amount of time in an unsteady case. When I create the profile I do not see how to set this velocity. I looked in the tutorial, but they use a UDF, which seems very unnecessary for just a constant movement. Thank you in advance, Hamish
