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.

Compute the inner product $(\nabla \phi \cdot F)$ .

Computes the weak Green form of advection terms (without boundary integral), i.e. $(\nabla \phi \cdot F)$ where for example $ F=uV $ .

Parameters

F	Fields.
outarray	Storage for result.

Note: Assuming all fields are of the same expansion and order so that we can use the parameters of m_fields[0].
