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 res...

Re: FreeCAD and ParaView

It looks like principal stress vectors are only exported to ParaView for reinforced material, or, I am doing something wrong (that is very possible :lol: ). Can some explain to me why it happens ? Which FreeCAD version do you use? You should use latest 0.19 dev versions. See https://forum.freecadwe...

Re: FreeCAD and ParaView

Hello, I tried to do tutorial under the link https://wiki.freecadweb.org/Post-Processing_of_FEM_Results_with_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 i...

Re: Principal Stress Plots

I calculate eigenvectors in src/Mod/Fem/feminout/importToolsFem.py and export them to VTK in src/Mod/Fem/App/FemVTKTools.cpp so that they are available in ParaView for plotting. Harry Hello, I am the new FreeCAD user, that is why please forgive if my questions will be trivial or it will look like I...

Re: Principal Stress Plots

Thanks @EkaitzEsteban. I calculate eigenvectors in src/Mod/Fem/feminout/importToolsFem.py and export them to VTK in src/Mod/Fem/App/FemVTKTools.cpp so that they are available in ParaView for plotting. The white arrows are indeed the maximum principal stress vectors and the colors the von Mises stre...
