Hi, @SaeranVasanthakumar .
I hope you are well. It’s been a while but I am finally picking up on this again 
I was doing some tests and I have a test model that looks like this:
In the image above, the thermal model is visualized as a red wireframe whereas the test points for the heatmap is visualized as green test points. Let’s say we have 100 surfaces and 500 test points.
Using this formula:
Qrs = a * e * sb * A * (Tsrf^4 - Tenv^4)
The variables a, e, and sb are single values. A and Tsrf are 100 values since they correspond to the surfaces that will be radiating the heat energy.
My question now is: does Tenv correspond to the 500 test points? If so, does this mean our value for Qrs will be some sort of matrix of around 50,000 values which represents the relationship of each surface with each test point? In a way, each of the 100 surfaces will be calculated with each of the test points so that will give us a total of 50,000 values in total.
Is my understanding of this correct? Kindly let me know your thoughts on this. Thank you!
