I'm using CFX 14.5 to simulate flow inside a chamber. I need to use a small fan rotating. For this, first I created the chamber domain because is more complicated. Inside the chamber, I removed a volume of a cylinder and insert the impeller as a second domain. After, I drew the cylinder involving the impeller. Therefore, I have 3 domains: chamber, impeller and cylinder (See attached).
On CFX-Pre I set the chamber domain as stationary with its boundary conditions and the impeller and cylinder in a second domain, rotating. How can I set the interfaces (cylinder and chamber) properly? Is there any mistake in the geometry as I drew? I didn't now how to draw the cylinder and the propeller in the same domain, because when I unfreeze the cylinder, the impeller disappear.

Apologize for the English, Portuguese is my first language!

This is covered in the rotor/stator tutorials which come with CFX. Have a look at them in the documentation.
