flow inside a vane pump
 

i am doing a project on numerical simulation of flow inside a power steering vane pump.
I do not know how to model the pump for the simulation purpose.Also i do not know how to provide the rotational and transitional motion to the vanes.

kindly help me for the above mentioned problems..

i have done the modeling of the vane pump ,now i dont know how to simulate the rotational and translational movement in vanes using starccm.I am not getting any tutorials related to this.If anybody knows how to do this kindly give some sugestions.
