You could define your axis of rotation as the center of the face you want to solve (Define->Boundary Conditions, and select the fluid volume, then define your axis of rotation). Then to create the face you can create an iso-surface of constant radius (Fluent will use the axis of rotation you defined for the fluid as the axis for the surface).

Hope this helps, and good luck, Jason
