I want to make a 3D diffusion model. I'm using a "Block" and a "Sphere". Sphere is in side the block. How do I make the sphere empty, so it will be a hallow sphere inside the block. This might be simple, but I'm fairly new to COMSOL.

Thank you

You have to use the "Difference" operator. See the attached example.
