<div dir="ltr">Gate users,<div><br></div><div>I have a question regarding defining volume sources. Let's say I have a sphere that is inside of a cube. If I wanted my source to be the the whole space of the cube but NOT the sphere, how would I define that? I basically just want to define a volume source that effectively 'goes around' other volumes. From what I can read in the manual, it seems like I would only be able to specify the entire cube as a source, rather than 'a cube minus a sphere' type of source.</div>
<div><br></div><div>Any help is appreciated, I really need to know if this is possible, or if I have to start thinking of different ways to model some experiments of mine.</div><div><br></div><div>-Amy</div></div>
