Thanks, Laurent.

Seems to work. I'm trying to run the mesh creation with criteria as
follows... I'm seeing a high number of tetrahedra though... Higher
than I'm expecting.

I want high-quality elements of roughly 10mm edges, to begin with. (I
would like 20mm later on if I can).

Does something like this look reasonable? High facet angle, say 45
deg. Facet distance a=10mm. Is the facet size root(3)/4 x a^3 (=43.3),
and the cell size root(2)/12 x a^3 (=117.9)?

Mesh_criteria criteria(facet_angle=45, facet_size=43, facet_distance=10.0,
                         cell_radius_edge=10.0, cell_size=118);

Does that make sense, or not necessarily. I seem to be getting more
tets "to refine" than I expect.

Michel
