<div dir="ltr">Hello GATE users,<div><br></div><div>I am currently writing my first simulation and am wondering about geometry definitions. What I am trying to define is a volume that covers a circular surface, with a square 'hole', essentially a thin cylinder 'minus' a thin box. Is defining a volume like this possible? </div>
