Introduction
An edge load is a set of known, timevarying, distributed forces and moments applied to edge EdgeName. This edge must have an associated curve CurveName. The bodies associated edge EdgeName can be of the following two types
 Beams: in this case, the edge load is applied along the curve that defines the geometry of the corresponding beam element.
 Shells: in this case, the edge load is applied along the curve that must be one of the bounding curves of the shell element.
Loading components
The edge load consists of a number of individual loading components, each defined by a subsection introduced by keyword @LOADING_COMPONENT. Each subsection can define the following parameters.

The spatial distribution of the loading component is defined by one of the following keywords.
 @APPLIED_FORCE_ALONG_i1: distributed forces acting along inertial axis i_{1}. The spatial distribution of the loading is described by 1D function, Fun1dDistribution, of type FORCE_ALONG_i1.
 @APPLIED_FORCE_ALONG_i2: distributed forces acting along inertial axis i_{2}. The spatial distribution of the loading is described by 1D function, Fun1dDistribution, of type FORCE_ALONG_i2.
 @APPLIED_FORCE_ALONG_i3: distributed forces acting along inertial axis i_{3}. The spatial distribution of the loading is described by 1D function, Fun1dDistribution, of type FORCE_ALONG_i3.
 @APPLIED_MOMENT_ABOUT_i1: distributed moments acting about inertial axis i_{1}. The spatial distribution of the loading is described by 1D function, Fun1dDistribution, of type MOMENT_ABOUT_i1.
 @APPLIED_MOMENT_ABOUT_i2: distributed moments acting about inertial axis i_{2}. The spatial distribution of the loading is described by 1D function, Fun1dDistribution, of type MOMENT_ABOUT_i2.
 @APPLIED_MOMENT_ABOUT_i3: distributed moments acting about inertial axis i_{3}. The spatial distribution of the loading is described by 1D function, Fun1dDistribution, of type MOMENT_ABOUT_i3.
 The temporal schedule of the loading component is defined by a time function, Fun1dSchedule, of type TIME_FUNCTION. This keyword is required. No default walue is provided.
 Scaling factor s is associated with the loading component. The loading component is multiplied by the scaling factor. (Default value: s = 1.0)

The loading component can be of two types: dead loads of follower forces, depending on the value of flag FfFlag defined by keyword @FOLLOWER_FORCE_FLAG. (Default value: FfFlag = NO).
 If FfFlag = NO, the loading component is a dead load, i.e., it acts in a fixed direction in space.
 If FfFlag = YES, the loading component is treated as a follower loading, i.e., the direction of the applied forces and moments will rotate according to the rotation of the structural point on which the loading is applied.
 It is possible to attach comments to the definition of the object; these comments have no effect on its definition.
