how to set 2 boundary condition on a surface
 
let say i have i cubic volume.. on one of is faces, i would like to have a smaller face that i can define as another zone (velocity inlet)..

the bigger face is the wall and the smaller face is the face that i would like to define as velocity inlet.

How can i meshed this volume

you can make inlet geometry at one side of cubic face and then define inlet with different part from other face.

how am i going to do that ?? my problem in that once i've created the volume and a smaller size face in the cubic surface, the meshed file won't detect it as a zone in fluent. so, i can't define the booundary.
