Hi Logan,
I know this is a quite old thread but I still hope for an answer.
I was looking for a case to validate my radiation setup and found this thread.
With the viewFactor model, I was able to recreate your results.
But can you tell me how you calculated the analytical view factors? I looked up some books for radiation but could not find the answer.
