Mesh values to contour curves


I have a 2D mesh that I coloured based on mesh element value (scalar value from Finite Element simulation). Is there any way to convert this into contour curves (boundary curve for each separated zone of color)?


You could probably deconstruct the mesh, sort the faces by colour, re-join the sorted faces to form individual meshes, and extract the naked edges from those.
It’s hard to say without a file, though!

Thanks, it works perfectly. Do you know how to decompose curves into lines and arcs?

You’re welcome. Polylines can be exploded into individual lines and curves into segments.
