[Paraview] Calculate Edge Lengths in Unstructured Grid

[Tim Gallagher]

Thomas, 

You can use the MeshQuality filter to compute the Edge Ratio for tetrahedral cells. This will give you a field called Quality in your dataset. You can then compute the statistics on it using other filters as needed. 

That should do what you are looking for. The definitions used in the MeshQuality filter can be found at: http://www.vtk.org/Wiki/images/6/6b/VerdictManual-revA.pdf

Hello Community, 


I'm trying to calculate the min/max/mean edge length (or even an edge length distribution) in a tetrahedral element mesh specified as an unstructured grid in Paraview. I've played with the 'Extract Edges' filter, however, wasn't successful so far. Does anybody know how I could do that? Thank you for your input! 


Best, Thomas Fastl
