[Gmsh] more tets than hexes in hex-dom mesh of cube

'Tis fixed already. I downloaded and compiled the development sources
(svn version 20179P) and the results for the cube case are greatly
A uniform size field produces a structured-type mesh with hexes
throughout. Non-uniform size fields produce hex-dominant meshes, the
percentage of hexes dropping as the non-uniformity increases.
I attach an example, hexDomCube_3.png, which has been generated using a
diagonal size field. The characteristic length is smallest at the
origin and largest in the opposite corner. The image shows the hex
cells only; the voids show the locations of the small number of tets,
prisms and pyramids.
Great work. The Hex-dom method will be popular for CFD analyses with
large gradients and complex domains.
