Description

ElementGeometry1D is used to define cross sections for beam elements. Currently, the following types of cross sections are available: rectangular, circular and pipe.

Usage

  1. There are several ways to invoke the command:
    • Press the Beam cross section button.
    • Select the Model → Element Geometry → Beam cross section option from the menu.
  2. Choose the type of cross section and specify the necessary dimensions:
    • Rectangular: width and height,
    • Circular: diameter,
    • Pipe: diameter and thickness.
  3. Optionally, press the Add button in the task panel and then click on the edge you want to have a prescribed cross section. If the edge selection is free, all the remaining edges (whose cross section is not defined by other FEM ElementGeometry1D objects) will be automatically assigned.

Properties

  • DataSection Type: specifies the type of the beam section (Rectangular, Circular or Pipe)
  • DataCirc Diameter: diameter of circular section, used if DataSection Type is Circular
  • DataPipe Diameter: diameter of pipe section, used if DataSection Type is Pipe
  • DataPipe Thickness: thickness of pipe section, used if DataSection Type is Pipe
  • DataRect Height: height of rectangular section, used if DataSection Type is Rectangular
  • DataRect Width: width of rectangular section, used if DataSection Type is Rectangular

Limitations

  • Other types of cross-sections available in CalculiX (elliptical, box and general) are not currently supported. One can edit the input file to use them.
