Yes, I confirm both points you mentioned in the previous message. When I work on the example file "FEM 3D cantilever" it looks like that:
1. in the initially defined pipeline, I can choose principal stresses (all three types);
2. when I define new pipeline on my own, they are missed ....
As a result principal stress vectors are NOT exported to VTK file and visible under ParaView, and I am not able to enforce orientation to line glyphs along e.g. major principal stress vectors.
On the other hand, I am more calm now that this is not only problem on my side, because I was afraid that I am doing some trivial mistakes
