Hi Sarih,
Thanks for your patient reply! Sorry for the time of the image that I presented and it is 12:30 09/20. The final images your shared were obtained from the script that I uploaded, right? The problem is related to the unreasonable black images the direct sun coefficients simulation. I corrected the error you mentioned and it didn’t influence the simulation.
I tried to not use accelerad command and use the original command such as rcontrib and rpict. At last I got the images of the direct sun coefficients simulation as expected.
The problem is linked to the command accelerad_rcontrib @Nathaniel_Jones to make the black images:
There could be some problems about the command accelerad_rcontrib.
