IMHO it shoudl be named FemConstraintGeneric instead FemGenericConstraint

It should be easy to just do find and replacement. I will do it later.
I am stuck on the json serialization error.

that is silly error, should be x- y- z-component. I also have another way to input vector, just as C++ constraint type (direction + mag), I have not fully tested, could be added in the future https://github.com/berndhahnebach/FreeCAD_bhb/blob/8d2f730a43e213d8212385151d1075da4f730bcb/src/Mod/Fem/femg...

PR sent to your fembodyconstraint branch https://github.com/berndhahnebach/FreeCAD_bhb/pull/63 BodySourceWidget -> ConstraintInputWidget merged InitialValue and BodySource into FemGenericConstraint FemBodyAcceleration -> FemConstraintAcceleration InitialPressure instead of InitialTemperature as a de...

I agree there may be no need of 2 classes "InitialValue" and "BodySource", but for sure need 2 functions, makeInitialValue(), makeBodySource(), or even more, makeHeatSource, makeSelfWeight() , et, to help script users. while makeAcceleration() is a better way than selfWeght, see Ansys FEM, there is ...

Thank you for your effort, I will pull your branch, to do more code chck. + I can make a unit test + for naming and place to put them, I will hear your advice, and other forumers. I did a lot of code formating to make the code fit in https://github.com/FreeCAD/FreeCAD/blob/d0f749b56e33ffde212fb5df74...

From a programmer view, their implementation is similar , but from CAE user view to solve Partial diff equations(PDE), initial values and body source are distinct things. https://fenicsproject.org/pub/tutorial/sphinx1/._ftut1003.html equation 1 Body source is the `f(x)` item in equation 1, it has di...

sorry for the misunderstanding, I do not mean your code, but overall data passing in femmesh utility functions written in python. if all meshing nodeset can be done in Cpp, it will be great. However, I fully agree with you, it is not current fem module dev priority. python is fine

Thanks for the file. I will submit a fix, soon. Fortunately, XDMF still works. Is the XDMF format in its current form still compatible with fenics? I ask this, since I wrote the export function between fenics 2016 and 2017, and I know there was a large API change in fenics. Further I am not interes...

Thank you for your explanation. I am looking forwords to this feature for my FenicsSolver. To continue on python data structure. numpy is prefer and it is easy in pybind11, possible and hader in C-API. As there is much effort to do so, just leave it as it is. xml writing is broken, but it is easy to...

Great Job, Joha2! It is highly desirable to have group support for FemMesh in FreeCAD. I have not got the experience in SMesh programming, but I guess you code is fine when I read througb your code. I wonder if `theID` in `int FemMesh::addGroup(const std::string TypeString, const std::string Name, c...
