Air Gap modeling in Thermal Analysis
 

Hello!

I have an external wall of a building, which is shown below (click on link to see the pic):

While in Ansys workbench Stady-State Thermal Analysis everything is clear with infill walls, or metal bars, or aluminium - it is not completely understandable to me how to model an AIR GAP between two layers of infills and between an infill and aluminium, as it is shown on the picture.

Can you please guide me with this issue? Or which solver should I use (maybe something else than solber in stady-state thermal analysis?)

Best regards,

Can someone please help me with that Issue?
I can't understand how technicaly model the mentioned above construction in CFX. While I have the model in .SAT file from Design Modeler, I can't understand how to set materials in CFX.
