Edge Load
Add an Edge Load as a force distributed along an edge (3D models) or boundary (2D models).
Force
Select a Load typeForce per unit length, Force per unit volume, or Total force. Enter values or expressions for the components.
FL
N/m
FV
Ftot
When Force per unit volume is selected, the given load is multiplied by the cross-section area. This option is useful for modeling body loads like gravity or centrifugal loads.
After selecting a Load type, the Load list normally only contains User defined. When combining the Truss interface with another physics interface, it is also possible to choose a predefined load from this list.
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.
 
You can add the Phase subnode to specify the phase of this load in a frequency domain analysis.
