Hello CGAL-Users,

since I'm pretty new to CGAL this question might be quite basic, but I couldn't solve this problem myself and wanted to ask for help. I've managed to generate a finite element mesh from medical imaging data using the '.inr' format and I'm super happy with the quality of the tetrahedral elements. However, the external surface of the mesh is quite rough and I wanted to know if there is an option to smooth it? I'm aware that this might reduce the quality of the entire mesh slightly, but I'd accept that for a more smooth surface. Currently I'm using the following code to generate the mesh:

C3t3 c3t3 = CGAL::make_mesh_3<C3t3>(domain, criteria,

                                           CGAL::parameters::lloyd(), CGAL::parameters::odt(),

                                           CGAL::parameters::perturb(), CGAL::parameters::exude());

Does anybody know a way to perform a smoothing step after the mesh generation in CGAL? Is this actually possible within CGAL or is the scope of the software to obtain better element quality while accepting more rough surfaces? Thank you very much in advance!

Best, Thomas Fastl
