There is an undocumented parameter that you may want to try... Add `facet_topology=CGAL::MANIFOLD,` in the parameters of `Mesh_criteria_3`, to enforce the manifoldness of the output. However, if mesh domain has not a manifold surface, the execution may loop and eventually crash. Use it carefully.

Thanks for the advice, however, it seems that the non-manifoldness of the surface mesh is introduced somewhere in the optimization steps. Adding the manifold-parameter alone didn't help, but adding it together with "no_lloyd(), no_odt(), no_perturb(), no_exude()" produced a proper manifold mesh. Just exude alone also seems to be fine, still.

Best,

Patrick
