No, you only have to define your rotor domain (surface in 2d) as rigid body in the moving mesh panel.
But in Gambit you have to set 2 kinds of fluid domain: one for stator, and one for rotor, else you cannot pick the rotor domain.
So you need in gambit to define as BC:
-your inlet
-your outlet
-your 2 interfaces
-your 2 fluid domains

in Fluent:
-define the interfaces by picking the 2 edges (already defines in gambit)
-in moving mesh panel, just define the rotor domain as rigid body and give the right angular velocity

Maybe you need to create the surface from your fluid zone, check here: http://my.fit.edu/itresources/manual...876.htm#156597

Please can u show me in the pic I attatched earlier,the explaination u gave above ..also i couldnt set rigid body when i was setting the bc for rotor..

use this tool for defining your 2 fluid domains:

The easiest and safest way to setup the Sliding Mesh simulation is to setup a MRF simulation first and begin the sliding mesh simulation after few iterations. Define the rotating volume as the MRF domain and specify the rotational velocity and axis. After few iterations, on the Text User Interface activate Grid>Modify zones>MRF-to-sliding mesh. This should identify neccesary interface and prepare the sliding mesh boundary conditions.

Even I tried doing this example..max/kk I wanted to ask if the rotor domain is given angular velocity..then how do you get the effect on actual rotor surface which is slotted,pls clarify... also can this animated?
