Related to this problem, I'm still trying to find a solution, is it
possible to use physical groups to force the mesh? If I set up certain
surfaces as groups it no longer crashes, but only meshes 2d, 3d still
doesn't work generally, or one of the 2 regions 3d meshes, but not both.
I've tried overlapping the meshes, defining holes everywhere I can think
of, but in the end, having a void in one region directly ajacent to the
other just seems to make both very unhappy.

Thanks David,
I tried that, but now it meshes the 2d surfaces fine, but complains
that "Error : No tetrahedra in region 3" (which is what corresponds
to the lower rectangle. Probably because its effectively open now,
even though its still effectively bounded on the top by volume 116.
The issue seems to be the overlapping boundary between volume 3 and
116, which is where surface 13 (the bottom of the void) and 18 (the
top of the "surface" or volume 3) intersect. Not sure how to get
around that, how do you force it to allow you to close the bottom
region, but at the same time use the boundary as a void in the upper
region.

Hi Shawn,
I think the best solution would be to define Surface 13 as a hole in
Surface 18.
