Description

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

How to use

1. Press the FEM ElementGeometry2D button, or press C then S keys.
2. Define a thickness parameter.
3. Optionally click Add in the Task panel and then click on the face you want to have prescribed thickness. If the face selection is free, all remaining faces (which thickness is not defined by other FEM ElementGeometry2D objects) will be automatically assigned.

Limitations

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

Properties

DataThickness: specifies the thickness of the shell.

Notes

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.
