STedsFEM is a Freecad workbench for structural analysis for 3D model. It works on FreeCad version 1.0 & 1.1
It used core EdsFEM for calculation. Initial goal: create a separate tool to cross-check versus Pynite core results..
It was derived from the Structure Tool workbench -by Maykow Menezes ( )
Some functions updated as per Structure Tool Enhanced workbench- by Buildsmart888 ( )
Core code EdsFEM - by Eduard Hendriksen ( )
Special thanks to Maykow Menezes, Buildsmart888, Eduard Hendriksen. This workbench was used Claude, ChatGpt in development.
- Sketching members model by line command.
- Select lines then click "Define member" to add parameter "Material", "Section"
- Assign materials, section, load on members, constraint points.
- Box selection (shift + B) all model to select all defined loads, members, material for analyst --> hit Calc Structure
- It will create CalcFEM object, in itself will got results list such as moment, shear, displacement, reaction.
- Select CalcFem object -> hit command Diagram to show diagram object, in it got options to show moment, shear, axial forces diagram.
- Select CalcFem object -> hit command Displacement to show displacement object, in it got options to show displacement diagram
- Similar for reactions
Those steps are quite similar with Structure Tools
Note Section command originated from Structure Tool workbench to define section properties from closed shape sketch. In StedsFEM, it can import from text file which got section properties info instead of sketching.

EdsFEM core was included in workbench. Currently it only works for 3D models not 2D plane
