ElementGeometry2D is used to define thickness of 2D FEM elements, all or lying on the chosen surface.


  1. There are several ways to invoke the command:
    • Press the FEM ElementGeometry2D.svg FEM ElementGeometry2D button.
    • Select the Model → Element Geometry → FEM ElementGeometry2D.svg Shell plate thickness option from the menu.
  2. Define a thickness parameter.
  3. Optionally press the Add button in the task panel and then click on the face you want to have a prescribed thickness. If the face selection is empty, all remaining faces (whose thickness is not defined by other FEM ElementGeometry2D objects) will be automatically assigned.


  • Analysis combining shell elements with solid or edge elements is not supported in the current version (FreeCAD 0.18).


DataThickness: specifies the thickness of the shell.



For viewing results from CalculiX solver on the mesh expanded to the prescribed thickness, property Beam Shell Result Output 3D in the FEM SolverCalculixCxxtools need to be set to True.
