How to make inner boundaries selectable in COMSOL?

Estiivan · April 7, 2017, 09:34

Probably quite simple beginner's COMSOL question. I am trying to have a block and a cylinder inside the block. If I draw first block and put cylinder inside of block in the middle, how can I make it so that volume inside cylinder would not be anymore part of block (but just of cylinder)?

I need to have boundaries of cylinder inside the block selectable. If I just put the cylinder inside the block as I have, then only the bottom and top surface of that cylinder seems to become selectable.

Here is a picture. How can I make cylinder walls to be clickable (selectable)?
