wall..interior..interface

dear all,

i had a chamber and air nozzles INSIDE the chamber in one mesh file.i want the air nozzles to flow out into the chamber.

1st trial BC SET UP: air nozzle's outlet: interior air nozzle's wall: wall

RESULT: the velovity vector shows a flow going through the air nozzle's wall and some of air from the chamber seemed to flow from the chamber into the nozzles through the nozzle's outlet.

2nd trial BC SET UP: air nozzle's outlet: interface air nozzle's wall: interior

problem: i cannot define the grid interface bcoz it involves only one interface: nozzle's outlet. i go through some fluenbt's tutorial. in order to define grid interface, they must read two mesh files. what about my case?

i would like to ask for help or suggestion for my case.
