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:
- 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
- Solve the system of equations from within the FreeCAD GUI.
- 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.

- Analysis container: Creates a new container for a mechanical analysis. If a solid is selected in the tree view before clicking on it, the meshing dialog will be opened next.
- Material for solid: Lets you select a material from the database.
- Material for fluid: Lets you select a material from the database.
- Nonlinear mechanical material: Lets you select a material from the database.
- Material editor:: Lets you open the material editor to edit materials
- Constraint fixed: Used to define a fixed constraint on point/edge/face(s).
- Constraint displacement: Used to define a displacement constraint on point/edge/face(s).
- Constraint plane rotation: Used to define a plane rotation constraint on a planar face.
- Constraint contact: Used to define a contact constraint between two faces.
- Constraint transform:
- Constraint force: Used to define a force in [N] applied uniformly to a selectable face in a definable direction.
- Constraint pressure: Used to define a pressure constraint.
- Constraint self weight: Used to define a gravity acceleration acting on a model.
- Constraint bearing: Used to define a bearing constraint.
- Constraint gear: Used to define a gear constraint.
- Constraint pulley: Used to define a pulley constraint.
- Constraint initial temperature: Used to define the initial temperature of a body.
- Constraint heatflux: Used to define a heat flux constraint on a face(s).
- Constraint temperature: Used to define a temperature constraint on a point/edge/face(s).
- Constraint body heat source:
