Sometimes, when there are multiple orders of magnitude scale differences in the sizes of parts in a Comsol model, you need to introduce additional internal boundaries. These can generally be made so as to not impact the solution (with either default or "continuity" boundary conditions specified on them). Then you can also set up the meshing to be at different levels of fineness within each geometrically-hierarchical level, which often helps. However, these tricks do not always work. In those problematic cases, I believe you are supposed to link prepare your structures as assemblies (is that the right term?) rather than let them form unions, but I haven't tried that technique.

Strangely enough, I tried again for the 100th time and just did a bezier and the a union and it worked. This program can be mighty pick at times.
