Detailed Description

Class for assembly of reaction- and interface forces.

This class can be used for linear problems which normally consists of a single assembly loop. For non-linear problems, the reaction forces for a given solution state is calculated during the subsequent iteration where the solution vector of the previous iteration is used. In linear problems we therefore need a separate assembly loop where only the reaction forces are calculated. This class is provided to facilitate such calculations.

The class can also be used to calculate interface force resultants, for boundaries not associated with dirichlet conditions.
