[Gmsh] Surface mesh of an STL model

[Mike B.]

Hi Dave,

Thanks for the prompt reply.

So to STL mesh is determined by whatever created the STL model?.

Cheers,
Mike.

Hi Mike,

from:  http://www.geuz.org/pipermail/gmsh/2008/003744.html

....
Gmsh will not remesh these STL faces, though. It's something we will
reintroduce at some point, but the remesher is not ready yet.
....


Cheers,

Dave
