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??? :confused:

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??

Turbo topology of Fluent does not support whole impeller model.
