I am happy extract the relevant bits and dress it up with some notes/tutorial on what it all means. As ever, I just need to find the time. Where on the wiki does this go?

Done and ready for final review. Perhaps worth linking to this in the main tutorial page under the FEM category?

still need to have a look at your awesome tutorial :oops: ...

should we adapt this https://github.com/FreeCAD/FreeCAD/comm ... f6e4e5R545 to your principal stress calculation as well ?

Ah ok. Yes I didnt catch a potential NaN return from Calcilix, so that sounds like a good idea. However, anything downstream from this principal stress routine should be able to handle NaN values too. For example, what happens with this in VTK pipeline or VTK export?
