Add an Edge Load as a force or moment distributed along an edge.
Specify the coordinate system to use for specifying the load. From the Coordinate system list select from the following based on space dimension:
Select a Load type —
Force per unit length (the default),
Force per unit volume, or
Total force. Enter values or expressions for the components.
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.
