Hello,

I am attempting to simulate a valve opening. I know to do this I need to construct a UDF and define the CG motion to give it a velocity.

I need some help figuring out how to get started on the dynamic mesh. Here is a different valve opening simulation, but I am trying to do the same thing. Do I create a solid model of the zone where it moves, mesh it independently, and then append it to the rest of the standard mesh? Any resources would be appreciated. I am having difficulty finding tutorials and resources.
