Hello experts,

I'm trying to model a centrifugal impeller with stator blades (see image). I've read you can reduce calculation time with the use of symmetry.

Properties model:

Impeller = 5 blades
Stator blades = 35
Pitch change = 1 (Frozen rotor interface)

In my model I only used 72 degrees of the full model (1 impeller blade and 7 stator blades.

My question is as follows:

How do I model the impeller with the use of symmetry?

If I use symmetry on the faces it will just mirror the component so I need a different commando.

Thanks in advance.

Greetings,

I think you will find that you use rotational periodic boundaries, not symmetry.
