Non-convex surface problem

Hey everyone,

I have encountered the problem of “Non-convex” surfaces for shades in my model.

EDIT: I improved the geometry and it did not show as non-convex by the HB component (Find Non-Convex). However, when I ran the simulation, it still showed the same non-convex error.

Could you please have a look and suggest how to address this issue for these types of surfaces?

Thank you so much!
