hi,

I want to know --Can I use single rotating reference frame to simulate stirred tank with baffles? In this method the tank wall and the baffles are defined counter rotating walls. Therefore I need not use multi-frame of reference. Can I do this? Please tell me. Thinks.

I'm afraid you can't use a single rotating frame of reference. You should use either multiple rotating frames (MRF) or sliding mesh capability in FLUENT. The MRF is a convenient, much cheaper alternative to the full transient sliding mesh capability. Please refer to User's Guide.
