Is any current solver used through FEM workbench has 1D beam element to do plane and frame analysis (which is most commonly used for structural analysis of Steel and Reinforced Concrete frames). I am thinking to use FElt for this purpose.
which is an effort to make it to run on latest compilers and hardware.
Original FElt is at:
added Felt to the list of interesting solvers FEM_Solver
I wish to work on adding FElt as a solver in the FEM workbench.
For that purpose I have tried to understand how other solvers take input and show output in FreeCAD from the source code but that wasn't
much helpful.
So a pointer in the right direction would be really helpful.
last version on sourceforge is from 2009 and last windows version is from 2000 :shock: Only the non officeal github repo has activity. Which seams your repo! Has the project been reactivated on github?

wow thats pretty cool news. Just have a look at this branch ... There a new solver oofem was added. The methods to write the real data where filled with some explizit data for testing purposes. But it should give you an idea ... ... s/femoofem

Also have a look at z88 solver in femsolver directory. Ahh and ask, ask, ask. I would recomend to open a new topic for this.

I will start working on this now.

And the new topic is here.

That would of course be marvelous, but it's a huge and complex work... But one day hopefully, we'll get there!
I am writing a library for drawing such a concrete structure details. this is my github:

now i want to continue this library in freecad and extend it with FreeCAD capabilities. for this, i want to define a beamtype object that contain other objects like:
  • beam object: that contain top&bot geometry of beam, stirrups, stirrups's text, beam size text
  • top&bot main rebars, top&bot add rebars: that contain rebars and leaders
  • Axis, dimentioning and etc
this is my plane:

please give me your hints. in my country there are a lot of software for this purpose, you can download trial version of ETABSMATE for example:

Hey everyone, i know I'm pretty late to the game, but you know two very well developped branches that create parametric spatialized structures?

PathWB (generally CAM tool paths) and Slicing (3D printing).

Just thought I'd leave this out there, as perhaps there is there a coding approach to generate structured wires automatically from a volume.
