Default Pump stage: Simulation using momeuntum source???

hi,

I would like to simulate one stage of a PUMP. I know radial and circumferential velocity components at the outlet of rotor. (or in other words: in Inlet of diffuser blades). As I understood from CFX help, I should use general momentum source to achieve specific velocities known at outlet of rotor.

But im confused how to set up momentum source coefficient and velocity components??

Perhaps: Momentumsource_radial= momentum source coefficient* (VelocityLocal - VelocityGiven)

Is that true?????? then how to find Velocity Local???

Regards,
