Default Rotating-Stationary mesh interface in CFX

I create a mesh of a single passage for a compressor blade using Turbogrid, then ship the mesh to CFX for simulations. The mesh consists of a single domain called Rotor. It consists of an inlet block, main passage, and an outlet block. I am using the Turbo Mode Wizard to set up the boundary conditions. The simulation is run with a "Rotating" Component type to simulate the rotation of the rotor. I don't have a stator down stream of the rotor, however I want to analyse the flow in the non rotating, stationary frame of reference at the outlet of the rotor as this is the flow that would impact the stator. Is there anyway of easily changing the interface between the main passage and the outlet block of my mesh so that the outlet block is not rotating?

I'm not completely sure if I understand your question right. But you can evaluate variables like velocity etc. in a rotating domain in 'Stn Frame' (stationary frame).
Additionally, you can add a monitor point and select 'Stationary' as 'Frame Type'. I haven't used that yet, but I just added a monitor point for my next calculation - just to see what happens

Also a picture of your situation always helps us to understand your problem quickly.

The rotor outlet block in Turbogrid is needed only for mesh generation technique that we do not want really for CFD. What I use is to set the hub in the block as a counter-rotating wall so that it will be stationary. Shroud in the block will be included in your shroud stationary wall definition. Try to minimize the outlet block distance in Turbogrid, but still we need some. Good question.
