Edge Load
Add an Edge Load as a force or moment distributed along an edge.
Coordinate System Selection
Specify the coordinate system to use for specifying the load. From the Coordinate system list select from the following based on space dimension:
Boundary System (a predefined normal-tangential coordinate system)
Global coordinate system (the default; the standard global coordinate system).
Local edge system. This is the coordinate system defined by the beam cross-section orientation as defined in the Section Orientation subnode under Cross Section Data. The local edge coordinate systems directions are available as variables for plotting using an Arrow Line plot, for example: Under Beam>Beam Local System in the plot settings lists of predefined expressions, select Base vector (beamsys) x, Base vector (beamsys) y, or Base vector (beamsys) z.
Force
Select a Load typeForce per unit length (the default), 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 Beam interface with another physics interface, it is also possible to choose a predefined load from this list.
Moment
Enter values or expressions for the components of the moment edge load ML (3D) or Mlz (2D).
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.
