How do i ensure that a face i created in GAMBIT (for a 3D model) can be given a fan B.C. in Fluent?

Urgently need help in this as i'm new to these 2 softwares..

Thanks in advance!

As you select the face to define the boundry for the wall. you can simply create wall to that face . it is very easy to create the wall to fan by shift the boundry condition, in the boundry condition panal
