Stage or Frozen rotor
 

Dear all,

I am trying to simulate a centrifugal pump (impeller-volute interacton). Do you think that is better to use the frozen rotor algorithm or stage? Why?

I don't understand what the stage algorithm does? CFX help talk about a circunferential averaging in bands. What does it means? When this algorithm shoul be used?

Thanks to all.

Regards

This is all explained in the documentation. Can you tell us what bit of the doco you don't understand?
