Descrizione

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

Utilizzo

1. There are several ways to invoke the command:
   • Press the FEM ElementGeometry1D 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 remaining edges (whose cross section is not defined by other FEM ElementGeometry1D objects) will be automatically assigned.

Note

• 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 need to be set to True.
