I’m trying to run a simple radiation analysis. I get an expected result when the normal of the surface is facing inwards although results are mirrored. Results on the south wall show up on the north wall and vice versa, which makes sense, but not the results I’m looking for. In other similar topics, all say that normal of the surfaces has to be facing outward. When I flip the surface normal from inward to outward, I get results like image 2.
I’ve attached grasshopper definition here if someone could take a look at it or knows what’s going on.
