gmsh: Inner cube in outer cube

shangzung · October 7, 2009, 05:44

Hello,

I am slowly starting to feel comfortable with gmsh and with gmshToFoam. In a thread in a mailing list (http://www.mail-archive.com/gmsh@geuz.org/msg01203.html) I read that it is possible to just have a big outer cube and a small inner tube and then create a volume of the bigger cube minus the smaller cube inside but can't manage it with the GUI of gmsh. Did someone have to do this once?

I found out how to do this: When creating the volume in the GUI, I first have to select the outer cube and then the inner cube, so the resulting volume is automatically the one of the outer cube minus the inner cube!
