  Hi everyone, very new to Ansys Discovery (student version) and I'm trying to conduct a CFD on a model of the upper airways.
  
  The below red outline is of the outlet, with lots of facets. Inlets are similar (nostrils).
  
  How would i go about definining the inlet/outlets for a CFD analysis ? Appreciate any and all help on this !

  Watch this video and pay attention at the 3:40 mark for a method to replace those facets with a single face.

    Thanks a lot Peter! very helpful
    
    Do i have to convert my shape to geometry first using auto skin ?
    
    Otherwise when I split shape like in the video i just get a hole into the hollow shape, or if i cap the hole, it caps with a lot of facets again (see pics below).
