[Gmsh] [GMSH] remeshing capabilities

[Pierre JUILLARD]

Thank you very much for this information!

Is it possible to know the title of this paper, so that I can find it?
Also, do the examples illustrate this feature in GMSH (I mean, is it
possible to see how the *.geo file look like to see what kind of commands
should be used and do some trials with a mesh of my own?)?

Finally, just out of curiosity, does it replace the remeshing feature which
was existing in former GMSH versions, and that Christophe
talked about in this email
http://www.geuz.org/pipermail/gmsh/2007/002719.html?

I thank you very much again!

Best regards,

Pierre
