Hi,

I'm new in COMSOL and I'm trying to make an opaque object with a little hole in the center. My idea is the light is absorved at the surface of the obstacle and pass through the hole, but my problem is that the light pass all through the object.

I have tried putting wall conditions on the obstacle (freeze) but the rays are stuck there and don't pass through the hole.

I'm doing an optical array and everything works fine except for this part. If someone with more experience can help me I would thank you very much.
