Rotor annulus oil pump Moving mesh CFD
 

Hi all, I am new to moving mesh type problem. I have rotor amnnulus kind of oil pump. Rotor has one teeth (lobe) less than outer annulus.This is positive displacement kind of pump.I need to analyze it in CFX 11.0. Can someone suggest good strategy to do this? How can I set the problem?

Thaks in advance
