Hi,
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?
@mwestphal Thanks for responding promptly. This is the data file vtk file.
the filter name is Extract region surface. The problem was that I could not select the data I want to begin with (using the select data) tool.
An update…I found a way to make the coordinates closer with no extra whitespace, now I can use the filter correctly. It seems the extra whitespace was causing an issue.
