Hello. Recently my University stopped buying the gambit licence and now we're on ICEM. Now I'm trying to build a geometry for meshing in ICEM, and I'm trying to create a wind-tunnel-like environment, with a wing in it.

If I were on gambit, I would create a volume for the wing, and a volume for the wind-tunnel, then subtract the small one from the big one. But I couldn't figure out how to do that on ICEM. I could still create two bodies on ICEM, but it doesn't seem to have a subtract function. Can I actually do the subtraction of volumes in ICEM like I did in gambit? If not, could anyone please suggest a way to build such geometry? Thanks in advance.
