I have an unstructured grid data vtk file of a volumetric mesh. I’m trying to extract region surfaces from that mesh, but it’s returning an error saying what I have is polydata while this filter needs an unstructured grid.
Anyone knows why this might be happening?
To give a bit of a context, the vtk file itself was generated by changing the points data of a template vtk file that has the connectivity list I need. The region surface extraction works fine in the template.
Can having more than one space (tap) between the coordinates cause this issue?
