Hello Regina,
While the approach that Linus described should still work, the internal boundary conditions called Thin Impermeable Barrier, which was introduced after Linus's post, is a much more direct solution. It saves you the need to form an assembly and work with pairs.
It looks like the Thin Impermeable Barrier condition was introduced at version 4.3b, see www.comsol.com/blogs/this-just-in-comsol-multiphysics-4-3b/ .
Best,
Jeff
