Well, ParaView should never crash so I would say you have<br>
found a bug. I looked at the file you put up and it didn't<br>
appear to have problems in the connectivity array so running<br>
ParaView through valgrind is the next step but I don't have<br>
the time to do that right now. I was able to replicate your<br>
crash, though.<br>

The cells (triangles) are a function of the points, so if the triangles look correct the connectivity info should implicitly be there, no? So there is not a way to take triangles that look like a mesh and make them into an actual mesh in the paraview/vtk framework?<br>

well if the mesh is arbitrarily broken then VTK will not help you. you<br>
may need a meshing application.<br>
