How to define number of blades using rotational periodicity in cfx-pre?
 
I am trying to simulate rotation of a 10 blade turbine fan. I understand that by using periodicity, 1 blade can be used to simulate the 10 blades, as seen in the multi-phase flow tutorial in cfx 13. I also did the drop curve for cavitation flow simulation in the tutorial.

However, what I don't understand is how do you define the number of blades? If I have ten blades then the rotational periodicity is 36degree? Where do I specify that?
