Description

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

Usage

  1. 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.
  2. Specify the shell thickness.
  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.

Limitations

  • Currently, analyses combining shell elements with solid or edge elements are not supported.

Properties

DataThickness: specifies the thickness of the shell.
