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.

If you have ICEM just import the mesh into it and again export. It will work
