Importing Hypermesh file to ANSYS Fluent

Hello, I made a CFD mesh using hypermesh to simulate heat transfer from flowing fluid across a pipe wall. 

Components created are:

-Steel pipe (solid)

-fluid flowing inside (fluid)

-ambient air outside (fluid, in the form of an enclosure)

-inlet (inside fluid 1 surface end)

-outlet (inside fluid other surface end)

 

Since I am not quite experienced with Acusolve I chose to work in ANSYS Fluent. I exported meshed file in NASTRAN. Then imported it into Fluent. But in Fluent there are no boundary conditions as  'Inlet' & 'Outlet'. Also certain unknown boundary condition parameters appeared, which I couldn't understand. 

I am hereby attaching the graphics window of Fluent for your considerations.

 

Kindly, help me in knowing if the components I created in hypermesh aren't correct, do I need to create 'Interfaces' too or anything I am missing which must be made to get desired boundary conditions in Fluent.

 

In anticipation of positive reply.
