> Has this been fixed? Yes and no. It turned out that it was not really a wrong calculation but a degenerate surface which gave a zero surface. That why I opened a blueprint to improve the class a bit such the user will be told if such case occurred. I have a slightly improved version here on my machine but I have to clean it up a bit. Should link it to the blueprint and add comment. Not sure about the appropriate status of the bug...

Status in DOLFIN: New Bug description: If a tetrahedron and triangle (converted from MeshEntities to CGAL Nef_polyhedron_3) are intersected and resulting polygon has non-vanishing area, BarycenterQuadrature computes quadrature wrong. Actually it gives zero area, since some loops are not entered in the BarycenterQuadrature::compute_quadrature function. (Such a intersection object has surprisingly *NO* half_facets). Check against CGAL is needed. _______________________________________________ Mailing list: https://launchpad.net/~dolfin Post to : [email protected] Unsubscribe : https://launchpad.net/~dolfin More help : https://help.launchpad.net/ListHelp
