Rotating and stationary walls

I'm new to Ansys CFX and this is my first post so my apologies if this is in the wrong section or the question is too easy
I made a schematic drawing here: https://www.dropbox.com/s/czpkzrjoca...%20element.png
Black are the stationary wall's, red is a rotating wall (the outside of a rotating filter element in real life), green the outlet en yellow the inlet.
The internal volume I modeled with Solidworks and imported into Ansys Workbench. Creating a mesh I used all standard values and created some 'named sections'.
Then in the CFX-Pre window, I think I need to create 2 domains: 1 that is stationary and had the inlet and the black walls and the 2nd one that has the outlet and the red rotating walls. (Am I still correct?)
Now, when I make my first domain I chose as location B41 (or Assembly, but this is the same), but this is the total model. For the second domain I thus cannot select another location since "The same location has been specified for more than one domain."
Can anyone please tell me how I am able to 'split' my assembly so I can make 2 domains? And should that be done in the Geometry, mesh or setup window in Workbench?
I tried to find a CFX tutorial with multiple domains but all files were already meshed so I have no idea how this 'split' was done.

It looks to me that you only have 1 domain. A domain would be a 3D volume. Your walls are boundaries, not domains. So in CFX-Pre you would insert boundary, apply it to the moving walls, and define the wall velocity.

I am doing CFD analysis of centrifugal pumps using Ansys having volute as stationary part and impeller as rotating part. For meshing I m using ansys meshing but i don't know how to create interface between impeller and volute.
