Hi Maarten,

we are currently working on such meshing problems
where one-dimensional sharp features of surfaces
could be respected.
However no working code is available right now.
Polyhedral surfaces with contrained edges are ou first target.
However, and it will take us a few months
to come out  with something working for such  surfaces.

Regards,
Mariette

Hello,

For making finite element models, I'd like to remesh polyhedral manifold
surfaces with borders, and I wonder if this is or will be possible with
the CGAL mesher tools.
The polyhedral surfaces consist of triangles, possibly of bad quality,
and they may be removed/smoothed out as long as the surface remains
homeomorphic and reasonably close to the original.
But it is important that the borders are respected because either they
have to agree with a volume in which it is embedded or they must agree
with other similar manifolds.

In the attachment I put two example images. The first is an example
manifold surface. The second is a 3D solid component defined by it by
embedding it in a cube. (The cube's ribs and corners must not be
smoothed out.)

Is it possible with the CGAL mesher?

Thank you very much,

Maarten Moesen
