Boundary Load (Thin Layer)
Add a Boundary Load node to apply tractions or pressure on edges adjacent to boundaries where the Thin Layer node is active.
Coordinate System Selection
The Global coordinate system is selected by default. The Coordinate system list contains all applicable coordinate systems in the model. Prescribed loads are specified along the axes of this coordinate system.
Force
Select the Load type — Force per unit area or Total force. Force per unit length is also available for 2D components. Then enter values or expressions for the boundary load components based on the selection and the space dimension.
•
For Force per unit area, the traction components are given explicitly.
•
For Total force, the total force is divided by the area of the boundaries where the load is active. Then it is applied in the same way as for a Force per unit area. When working with curved boundaries or local coordinate systems, use this option carefully, as the result is not always intuitive.
Linear Buckling
To display this section, click the Show More Options button () and select Advanced Physics Options in the Show More Options dialog box.
If you are performing a linear buckling analysis with a combination of live and dead loads, select the Treat as dead load check box to indicate that the load contributions from this node are constant. The default is that a load is proportional to the load factor.
For more information about live and dead loads, see Buckling Analysis.
