Fluent simulation of centrifugal pump

Hi! Im simulating 3 d geometry of a pump having a regenerative impeller. Although the file is read in FLUENT, I'm not able to define the turbo topology for the same. Can anybody help me wid da same???

Hi,

Did you pressed "Define" button after every boundary-surface setting?
You should only one click after all boundary-surface setting.

And Turbo topology is only applicable to blade to blade pitch domain.

no.. i didnt press define.. but, the problem is.. in the regenerative impeller.. i cant make out what the hub and casing is. Im simulating the entire impeller, so i don have any periodic regions.What should i do??

Hi,

Turbo topology of Fluent does not support whole impeller model.
