Setting up for Rotating 2D straight channel
 

Hello ! I am Pawan Garg.
I have been trying to setup FLUENT boundary conditions for the problem of Turbulent flow through a straight channel which is rotating at certain RPM in the plane of the channel.
I have not been able to get a converged solution!
What is the best way to set-up such a flow in the rotating reference frame.
I shall be thankful to you if you can guide me over the detailed setup of fluent boundary condition that can be suitably used for simulating rotating straight 2D channel.
Thank you in advance.
