[Gmsh] Different domains in a geometry

[Riad.HASSANI at unice.fr]

Hi Mikhail,
thank you for your help.
May be I'd be more clear with a little drawing. In the attached  
screenshot, I show two zooms of the zone where the problem occurs  
(intersection between two edges, but the interpenetration is very  
small).
I tried to tune the "Mesh.RandomFactor" parameter without success.
Best regards,
Riad
