After upgrade to Ubuntu 20.04, vtk-dev is broken ,so I can not compile freecad-daily any more, so I build my vtk9. When I built freecad upstream master latest 0.19, I run into problem with SalomeMesh, I know there are already some in-progress work to upgrade salome mesh, I hope once salomemesh updat...

I topped up 2 commits on documentation, one commit renaming, see PR to your branch. https://github.com/berndhahnebach/FreeCAD_bhb/pull/78 There is one file, with your in source notes, femobjects/ConstraintGenericDefaults.py I leave it to you to further clean it before PR to master. I run out my time...

I can add more document, in that case, doc will be much long than the code, what is why I think it deserves a page. I will do another top up tomorrow thank you

If you think necessary, A in-source documentation should be added to the class ConstraintGeneric to outline how to use this class, or add those doc into freecad wiki directly? I prefere in source. But more important would be a real use of one of the constraints. ATM there are two new constraints wh...

Rebase after stop for a while is kind of disaster to me :). I may add a bit in-source documentation then I hope to PR. BodyAccelation is a quite useful constraint. it can let FEA simulate linear acceleration, centrifuglal. It modelled after Ansys Mechanical https://studentcommunity.ansys.com/thread/...

I will have a look, it may take time to restart on that branch, as fem_gmsh have evolved a lot since then.

For fenics_ mesh, it was too outdated, should be removed.

two branches: https://github.com/berndhahnebach/FreeCAD_bhb/commits/fembodyconstraintqing your branch with some rebase errors reverted. https://github.com/berndhahnebach/FreeCAD_bhb/commits/fembodyconstraint completly rebased and all commits squashed, only bodyconstraint changes. Would you give it ...

Would be great. BTW: I have renamed all PythonFeatures in FEM, but did not renamed the dev branches. It will still work, but before merge we should rename them too. check femobjects and femguiobjects and femviewproviders directory. I can do the renaming if everything else works fine. I have renamed...

Thank you, I pull upstream master, the checkout my fembodyconstraint branch (left over in Feb, have not rebased to upstream master yet) then I pull your fembodyconstraint. I would expect no conflict, but I found still some conflict. I also have feeling, my git status, show lot of added files, (shoul...

I will give it a try this weekend, we got bank holiday, will let you know the result.
