Description
ElementGeometry2D is used to define the thickness of shell FEM elements, all or lying on the chosen surface.
Usage
- There are several ways to invoke the command:
- Press the Shell plate thickness button.
- Select the Model → Element Geometry → Shell plate thickness option from the menu.
- Specify the shell thickness.
- 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.
Limitations
- Currently, analyses combining shell elements with solid or edge elements are not supported.
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 toTrue
. - This feature uses the *SHELL SECTION card in CalculiX.
