It would be cool if we would found something without changing the mesh and without triggering nonlinear analysis.
Okay then I dig some more, my thought was that I'll use the EQUATION-card. But as mentioned then the nodes as elements need to be altered or rewritten.
But just of curiosity, why cant we rewrite the nodes/elements? I was thinking a constraint-like function that can be applied on edges that rewrites the already written .inp file. I know, I'm quite naive
Also not with an equation in the imp file as other suggested? If not, i want do help and look at the lists in the tracker or improve (unify) the usability. At least one mini fix i have found in PartDesign.
We may need to have another closer look. But we will need the this new object anyway. Solver Mystran is in master and solver Mystran is for sure able to do this rather simple. See former post of john. Solver Mystran is my choice ATM for beams and shells. I will spend time to better support them. Thus a new object to define hinges for shells and beams would be needed anyway.
Furthermore we will need to improve the beam section object to be able to define more cross sections. May be even free ones. This means to put in moment of inertia manually or even retrieve area and moment of inertia from a face modeled in FreeCAD. But this is another topice see https://forum.freecadweb.org/viewtopic. ... 20#p520457
