[Gmsh] about attractors

[quemere_patrick]

Hello,

I have successfully used gmsh to generate mesh fitted on hexagonal 
shapes (see jpg), thanks to "attractors" defined in my case for each 
hexagonal lines as :
 Attractor Line { c[indice] } = { 0., 0., 3.5 } ;  (and this, without 
using anisotropic algorithm).
You defined in a previous message the last coefficient (3.5) as the 
decay factor (see http://www.geuz.org/pipermail/gmsh/2003/000789.html)
But what is the real sense of it ??
Could you please give me some more details in the aim I determine this 
coefficient from my geometry (and not from several hazardous tests).

Thanks.
