Hi all,

I am working on a thermal analysis of a plasterboard wall assembly with an air gap between two plasterboards. One side of the outer plasterboard is exposed to the standard fire curve. The plasterboards are separated by a 12.5 mm cavity.

I was able to apply the fire boundary condition, but I am struggling to simulate the conduction and radiation effects within the air cavity that influence the thermal development of the opposite plasterboard.

Could someone please guide me on how to model this in 3DEXPERIENCE SIMULIA Structural Mechanics Engineer role?

Thank you in advance!
