The FEM Workbench provides modern Finite Element Analysis (FEA) workflow for FreeCAD. Mainly this means all tools to make an Finite Element Analysis are combined in one GUI.

The steps to do a FEA in FreeCAD FEM Workbench GUI are:

  • Preprocessing
    • Modeling the geometry, in which FreeCAD is already a nearly full-grown software.
    • Create an Analysis:
      • Create an FEM Mesh out of the geometrical model.
      • Add Constraints such as loads and support fixes to the analysis model.
      • Add a Material to the analysis model
  • Solving
    • Solve the system of equations from within the FreeCAD GUI.
  • Postprocessing
    • View Results inside FreeCAD GUI.

The above mainly describes how a FEA analysis is done inside FreeCAD FEM Workbench. For further documentation refer to the GUI Tools described later here.

As of FreeCAD version 0.15 the FEM-Module can be used on Windows, Mac OSX and Linux platforms. Since FEM Workbench makes use of external software, the amount of manual intervention until the FEM workbench is ready to use will depend on the OS that you are using. Check out FEM Install.

Reason for deletion: This template is not used any more. It is used by some obsolete translations but the content is already available in FEM Workbench.

(2018 November) This template is obsolete. The tools should be placed in the actual page FEM Workbench. This facilitates the translation of pages.
