Re: FreeCAD and ParaView
Hello,
I tried to do tutorial under the link https://wiki.freecadweb.org/Post-Proces ... h_Paraview. For that purpose I downloaded the proposed BEAM example. When I'm using REINFORCED MATERIAL, I am able to plot all principal stress vectors (major, intermediate, minor) afterwards in ParaView:
https://lh3.googleusercontent.com/pw/AC ... authuser=0
Unfortunately, later I changed material to homogeneous one, and I was surprised that in ParaView I am not able to plot principal stress vectors but only stress tensor components Sxx, Syy, Szz, Sxy, Sxz, Szy:
https://lh3.googleusercontent.com/tQ6le ... authuser=0
It looks like principal stress vectors are only exported to ParaView for reinforced material, or, I am doing something wrong (that is very possible ). Can some explain to me why it happens ?
Best regards
Damian

Re: FreeCAD and ParaView
Which FreeCAD version do you use? You should use latest 0.19 dev versions. See

Today I downloaded the newest version "FreeCAD_0.19.21775-Win-Conda_vc14.x-x86_64.7z" extracted all files and just opened "freecad.exe" from BIN directory. I did NOT do any other steps or maybe I forgot about something, did I? The final results is the same, and I am not able to plot principal stress vectors.
Re: FreeCAD and ParaView
- start FreeCAD
- open FEM 3D cantilever
- change to FEM WB
- Select CCX_Results object in TreeView
- File --> export --> FEM-result VTK
- export to test.vkt
- import back into FreeCAD ...
you are right they seam missing ... But they should be exported ... https://github.com/FreeCAD/FreeCAD/blob ... #L664-L666

Re: FreeCAD and ParaView
- start FreeCAD
- open FEM 3D cantilever
- change to FEM WB
- Select CCX_Results object in TreeView
- create a new PoostProcessing Pipeline (Results --> Post Pipeline from Result)
- double click the new pipeline --> Mode --> Wireframe Surface and Field misses the Principal Stress too.
But if you open the already existing Pipeline from the example file the principal stress is available inside FreeCAD for me.
Would you confirm ?

Re: FreeCAD and ParaView
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

Re: FreeCAD and ParaView
Thanks for confirm this. Lools like a regression was added somewhere. I will have a look.
