hi iam madhuri.i have geometry such a way that it has one volume rotating besides other one fixed.the rotating volume has 230 small tubes which are set into rotation.so i have done 2 gambit files one for rotating tubes and the other file for the other volume which is seemed to be the upstream for the rotating ones. i came to know that the results at outlet of first fluent can be inputted as inlet to another and i dont know how to do this.can any one let me know the step by step process of doin this.thanks in advance.

After getting converged solution from case (zone), you can append your case file through Grid-Zone-Append Case File and start solving further.
