See vtkFeatureEdges. A closed surface will have no boundary edges. Run
vtkFeatureEdges on your surface with BoundaryEdgesOn() to ensure their
absence.

You may also want to enforce that the surface has no self intersections,
which means that the surface will have only manifold edges.  Run
vtkFeatureEdges with NonManifoldEdgesOn as well to ensure their absence.


and use vtkmassproperties. Thanks.
