Detailed Description

A base class for describing how to solve specific equations.

This class is a base class for all solver implementations. It provides the underlying generic functionality and interface for solving equations.

To solve a steady-state equation, create a derived class from this class and reimplement the virtual functions to provide custom implementation for the problem.

To solve unsteady problems, derive from the UnsteadySystem class instead which provides general time integration.
