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 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, ...).

For some elements it may be better to obtain "vertex values" of boundary load to compute load vector directly using exact formulae.

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

overridevirtual

Computes components values of load at given point - global coordinates (coordinates given).

Parameters

answer	Component values at given point and time.
tStep	Time step representing time.
coords	Global (or local) problem coordinates, which are used to evaluate components values.
