[Gmsh] - Definition of volume with complex concave holes on the boundaries

[Johannes Wimmer]

Hello Simone,
do you need to generate such structures at random? You could also have a 
Voronoi cell being trimmed by two domain faces without a broken domain 
edge. In general, it is rather hard to write the *.geo file for these 
structures if there is still domain present. If you only want Voronoi 
cells (taking up the whole space) in an e.g. cubic domain, I recommend 
having a look at Neper: http://neper.sourceforge.net/

I've attached a pic of the structures i am generating, they're supposed 
to resemble asphalt concrete. Although i cannot give you my code right 
now, I could generate some geometries for you if you specify what you want.

Cheers,
Johannes
