Detailed Description

Abstract base class representing a point load (force, momentum, ...) that acts directly on or inside of some finite element.

Methods for returning values of load components and returning the position of load are provided.

Note: This class is not restricted to structural problems. For example, in thermal analysis, a point load load could be a point heat source.
