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
- 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.
- Press the
- Choose the type of cross section and specify the necessary dimensions:
- Rectangular: width and height,
- Circular: diameter,
- Pipe: diameter and thickness.
- 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.
Options
Properties
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.
Notes
- For viewing results from CalculiX solver on the mesh expanded to the prescribed cross section, property
Beam Shell Result Output 3D
in the FEM SolverCalculixCxxtools needs to be set toTrue
. - This feature uses the *BEAM SECTION card in CalculiX. It is explained at https://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node162.html
