[Paraview] display boundaries of 2D geometry

[Zenker, Dr. Matthias]

Hi,

is there a way to display the boundaries (edges) of a 2D geometry? I have converted my mesh to vtu using Elmergrid, so I have the IDs of bodies (=surfaces in 2D) and boundaries (edges) in a vtu file. Can I just display the edges having the same ID? The extract edges filter does not help.  What else could I try?

Thank you for a helpful hint,

Matthias
