Detailed Description

This class implements a linear boundary load (force, moment,...) that acts on straight segment.

A boundary load is usually attribute of one or more elements.

The boundary load describes its geometry and values (it is assumed, that user will specify all necessary dofs) on element boundary using isoparametric approximation. Elements can request the order of approximation (for setting up the appropriate integration rule order) and the array of values (for each dof) at specific integration point on the boundary.

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

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