[Paraview] Quadric Clustering on 3D Unstructured Grid (PV3.2)

[Sylvester Gerardson]

Hi Simone,

Thank you for your answer.

I am not sure I understand your suggestion. When I apply the 'Extract
Surface' filter only my (3D) surfaces remain and the Quadric
Clustering filter becomes available.

But I need the volume cells, not the surfaces. Am I doing something wrong?

regards,
Sylvester
