Hi all, I was able to put TesselationWrapper() in my script months ago, but now I can't anymore. When I try running the TesselationWrapper example given on the GitHub: tt=TriaxialTest() tt.generate("test.yade") O.load("test.yade") O.run(100,True) TW=TesselationWrapper() TW.triangulate() #compute regular Delaunay triangulation, don’t construct tesselation TW.computeVolumes() #will silently tesselate the packing, then compute volume of each Voronoi cell TW.volume(10) #get volume associated to sphere of id 10 TW.setState(0) #store current positions internaly for later use as the "0" state O.run(100,True) #make particles move a little (let's hope they will!) TW.setState(1) #store current positions internaly in the "1" (deformed) state the terminal gives me this: python: /tmp/buildd/yadedaily-1.14.0-54-f44c022~trusty/lib/triangulation/Tesselation.ipp:66: CGT::_Tesselation::VertexHandle CGT::_Tesselation::insert(CGT::Real, CGT::Real, CGT::Real, CGT::Real, unsigned int, bool) [with TT = CGT::TriangulationTypes; CGT::_Tesselation::VertexHandle = CGAL::internal::CC_iterator, CGAL::Triangulation_vertex_base_3, CGAL::Triangulation_ds_vertex_base_3, CGAL::Triangulation_vertex_base_3, CGAL::Triangulation_ds_vertex_base_3 > >, CGAL::Triangulation_cell_base_with_info_3, CGAL::Triangulation_cell_base_3, CGAL::Triangulation_ds_cell_base_3 > >, CGAL::Sequential_tag> > > >, CGAL::Default, CGAL::Default, CGAL::Default>, false>; CGT::Real = double]: Assertion `vertexHandles.size()>id' failed. I wonder why this happens. Thanks a lot! Shenyang
