I have a .pvd file generated from FEniCS containing some data points.
I would like to extract the cells/surfaces where a condition is met (data_value > 0.5), to export it afterwards to a .STL file. See the picture below as an example, I want to extract the red ring.
However, when trying
Find Data, I am only able to find points and cannot afterwards export the desired surface to STL.
If I try to reconstruct the surface from the selected data points with a
Delaunay 2D filter, the topological features (holes) are lost …
Thank you for your time.
