How can I view the rotation within a full rotation phase
 
I research on the pressure distribution of a volute with component impeller and diffusor. The impeller included a diffusor ring was splitted into a 1/9 part in entire circle with clearly defined periodicity.The interfaces between the rotor and stator were set to frozenrotor, in which a automatic pitch change will be used, while the interfaces between diffusor and volute were defined as stage with specified pitch angles.

The result seems to be not bad, but the problem is how I can view the whole rotation motion in 360deg. The streamlines flow only through the 1/9 part, though it looks fit. If i tried to copy the part in entire circle, i can only recieve idental the identical information about the 1/9part with 9 times copied. Because the geometrical construction of the volute along the outer contour is slightly varying , the pressure distribution in both diffusor ring and volute itself should be in 360deg quite different.

I need ur help indeed to tell me, if it is a definition mistake in simulation of my own or just a incorrect display setting? When it is a wrong view setting, how can i make it suitable?

Thank you so much for ur tipps:cool:

This is all covered in the tutorials. Have a look at the rotor/stator example.
