I wanted to examine the temperature of these two.&nbsp;&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;The thing is, most of the tutorials on the internet do not show how I can achieve this. Because the steel cladding will radiate the heat to the first layer of air, then it affects the temperature of the polystyrene in the middle of the structure, then ultimately affects the heat of the bigger size of air. I am not sure if I am explaining this clearly.&lt;\/p&gt;&lt;p&gt;Is fluent capable of doing this? What is the general workflow that I needed to follow to achieve the simulation?&lt;\/p&gt;&lt;p&gt;Here is another image in case the first one is not clear&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\"
