CFX VS FLUENT for sliding vane applications
 

Dear all,
I'm going to simulate a fluid machinery working like a sliding vane compressor.
What I need to be able to manage is:
- deformable domains
- moving domains
- sliding interfaces
- to make volumes of fluids appear and disappear during the transient simulation
Someone with greater experience than mine could recommend the best choice between Fluent (UDFs?) and CFX (multiconfiguration/user fortran?) for this specific application?
Thanx
