So in summary, I think the Paraview challenge is perhaps not the biggest one

Harry, thanks for your effort on this topic. But I think this is a very complicated (and time consuming)HarryvL wrote: ↑Fri May 18, 2018 12:16 pmI did some further research and found that the above problem has been solved elegantly by my ex colleagues in the Netherlands ...

The paper provides 11 closed-form expressions for reinforcement ratios ωxx, ωyy and ωzz that need to be evaluated for every stress point in the result set. The one to chose is the one that ensures that σc1<0 (no tension in any direction), is valid (ωxx, ωyy, ωzz >0) and minimizes total reinforcement ωtotal=ωxx+ωyy+ωzz.
I will give it a try and report back.
May be not if someone would be able to implement this somehow in FreeCAD or paraview result viewing. I assume this is what you have in mind harry?thschrader wrote: ↑Fri May 18, 2018 2:41 pmHarry, thanks for your effort on this topic. But I think this is a very complicated (and time consuming)
