How do I specify interface BC and/or eliminate the face after two face matching grid blocks are read into fluent.  Some general points.  Two zones have exact face matching grid faces and I can get compressible solutions individually. So the mesh is sound.  Fluent specifies interior wall when I match them up.  I am not sure if I should be concerned.  Opinions?

Hi,

If the bodies in contact are part of a multi-body part, the faces at the interface will be shared and assigned an interior boundary type when loaded into Fluent. If the bodies are separate parts, the default boundary condition will be a wall.

What is the BC for flow?   i.e. fully connected?  interior or flow is not an option.

face is only shared by one other body and interior is not one of the BC choice.
