Detailed Description

Class collecting the element matrices associated with a FEM problem.

The class is derived from LocalIntegral such that it may be passed as argument to the Integrand::evalInt and Integrand::evalBou methods.

The class has two virtual methods returning the Newton matrix and the associated right-hand-side vector, which can be reimplemented by sub-classes to implement different time-integration schemes, mixed formulations, etc. The default versions use the first element matrix as the Newton matrix, and the first element vector as the associated right-hand-side vector.
