Описание
ElementGeometry2D используется для определения толщины двумерных элементов МКЭ, всех или лежащих на выбранной поверхности.
Применение
- 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.
- Press the
- 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 the remaining faces (whose thickness is not defined by other FEM ElementGeometry2D objects) will be automatically assigned.
Ограничения
- Анализ, объединяющий элементы оболочки с твердотельными или краевыми элементами, не поддерживается в текущей версии (FreeCAD 0.18).
Свойства
ДанныеThickness: specifies the thickness of the 2D elements.
Примечания
- For viewing results from CalculiX solver on the mesh expanded to the prescribed thickness, the property
Beam Shell Result Output 3Din the FEM SolverCalculixCxxtools needs to be set toTrue. - This feature uses the *SHELL SECTION card in CalculiX for shell elements and *SOLID SECTION card for plane stress/strain elements.
