Dear All

I want to simulate a centrifugal pump impeller only, i think i made the mesh correctly, through bladegen and turbogrid. It is CFX turn now, and i am a bit confused regarding the BC, is the hub and teh shroud should be rotating fram only without set a rotation speed, the inlet is staionary or rotating, the outlet is rotating or staionary also the ref pressure is 1 or 0, do i configure th inlet as a static pressure or Sat. total pressure and the outlet as a mass or preesure. do also i should use a mass upgrade in defining outlet mass flow rate.

I would be appreciated if someone can help,

Many thanks in davnce
