how to define solid movement inside flow region in fluent?
 

Hi friends

I have a problem defining solid movement inside flow area in fluent. I am trying to simulate shut off valve closure in 2D using Fluent. I have tried defining UDF using CG motion, but the solid moves yet there is no change in flow pattern. I have also defined dynamic meshing using region remeshing. I am missing something here. Can someone please help me out?!!
