Detailed Description

This class implements a boundary load (force, moment,...) that acts directly on a boundary of some finite element (on side, face, ..). A boundary load is usually attribute of one or more elements.

The boundary load describes its intensity as a function of spatial coordinates. Elements can request the order of approximation (for setting up the appropriate integration rule order).

Elements take care, on which boundary the load acts on (side number, ...).

This class is not restricted to structural problems. For example, in thermal analysis, a boundary load load would be a heat source.
