Introduction

The FEM Workbench provides a modern finite element analysis (FEA) workflow for FreeCAD. Mainly this means all tools to make an analysis are combined into one graphical user interface (GUI).

Workflow

The steps to carry out a FE analysis are:

  1. Preprocessing: setting up the analysis problem.
    1. Modeling the geometry: creating the geometry with FreeCAD, or importing it from a different application.
    2. Creating an Analysis.
      1. Creating an finite element Mesh for the geometrical model.
      2. Adding Constraints such as loads and fixed supports to the model.
      3. Adding a Material to the analysis model.
  2. Solving: solving a system of equations using an external solver from within FreeCAD.
  3. Postprocessing: visualizing the analysis Results from within FreeCAD.

As of FreeCAD version 0.15 the FEM Workbench can be used on Windows, MacOSX and Linux platforms. Since the workbench makes use of external solvers, the amount of manual setup will depend on the operating system that you are using. See the FEM Install page for instruction on setting up these tools.
