Dear COMOSL community,
I am new to COMSOL and am looking to extrude this design to make it 3-D but I feel I am struggeling more than i should be. The goal is to end up with a solid disc with many THROUGH holes through which air can pass during simulation and one could see the grid through the holes in the disc. So far when i extrude the holes or the enitre circle, all the mini holes still seem to keep their bottom or base - so they end up like a cave instead of a tunnel.. Ive tried this with all the mini holes being curved or solid - yet still to no avail.
ive spent a good amount of time on this only to feel like an idiot..Any help would be very much appreciated!
