The ICE component in workbench is obviously worth checking out. Also ANSYS support will have examples of this. The ANSYS customer page also probably has some relevant stuff on it.

I am talking about the conditional connection control option on the interface. This is a new option in CFX. What version of CFX are you using? You can either apply the source term as a boundary...

It means you get a chance to custom make each mesh to each valve lift. This means you are likely to get better mesh quality than when you script it as the script is...

I would develop the mesh motion+remeshing algorithm on a simple model which you can run in a few minutes and debug quickly, not an engine model. So get this working on a simple version first before...
