Method for Solar Radiation Analysis Using Ladybug and Honeybee

Hello,
I am currently attempting to perform daylight analysis for an indoor space using a model featuring circular openings in an arched surface, as shown below. However, I am receiving the message shown in the image. Is there no solution other than dividing the arch into flat planes? I wish to perform the daylight analysis while preserving the curved surfaces of the analysis model.

when simulating the flat-split arch, the opening and the arch plane overlapped, and it worked well, but I dislike that the porosity of the opening is restricted.

Hi @ryusei can you share the file? I have a few thoughts on how to make things right but I will need some tinker time.
Typically the bugs don’t agree with curves surfaces, surfaces with holes, and circular holes even if subdivided

Thank you for your reply. I will share the folder with you. I appreciate your cooperation.
