[Gmsh] Mesh Element size

[Bertrand PIGEARD]

Bonjour,
I'm working on a project to translate GSDII file (2D format for microchip)
to a 3D geo format, we just had the thickness of layers. (Work base on
GDS3D http://sourceforge.net/projects/gds3d/ )

The full geometry is ok but we face issue with mesh. So we control the mesh
size of each point regarding the polygone areaand the mesh around the point.
We tried to find rules to get the mesh with no error but we still have
error with edge.
So can you give us some rules to follow to get the mesh working.

I can provide a geo test file but it's big even while zip (>10M)

Thanks for your work and Happy new year,

Bertrand

PS: I also open a bug related to 2D mesh. The meshGFace random (line 1120
and 1122) lead to error if the random function get twice the same value.
