Paraview closes when trying to open a simple vtk file

Hi!

I am trying to open this file in Paraview:

Poligono1.vtk (338 Bytes)

But Paraview closes when trying to open it. One strange thing is that this file has worked once and it has a very simple geometry with vtk_triangles. What may be happening? Can you help, please?

Thanks,

Marina

Hi,

Your file is ill-formed: if you open it in a text editor you can see at line 24 that a cell is declared containing the point id 8 but you have only 7 points (so max id should be 6).

That said, in my opinion, a warning should be displayed instead of a crash …

Feel free to open a bug report (maybe on the VTK repository https://gitlab.kitware.com/vtk/vtk/issues/new?issue[assignee_id]=&issue[milestone_id]=) and thanks for reporting !

Hi!

Thanks for helping me figure out the problem!
In fact, a warning would have made it easier to find the error.

Thank you again,

Marina

VTK’s legacy readers just need to be redone to not trust their input so much. I’ve got a nice pile of crashers laying around for anyone interested in fixing the bugs (though I suspect just following the specs and writing new implementations would be more productive).
