Detailed Description

The main implementation of an CRTP-base class for operators using a grid-function coefficient to be used in an Assembler.

An Operator that takes a GridFunction as coefficient. Provides quadrature rules and handles the evaluation of the GridFunction at local coordinates.

The class is specialized, by deriving from it, in GridFunctionOperator.

Template Parameters

Derived	The class derived from GridFunctionOperatorBase
LC	The Element or Intersection type
GF	The GridFunction, a LocalFunction is created from, and that is evaluated at quadrature points.

Requirements:

Constructor & Destructor Documentation

inline

Constructor. Stores a copy of gridFct.

A GridFunctionOperator takes a gridFunction and the differentiation order of the operator, to calculate the quadrature degree in getDegree.

auto const& getQuadratureRule	(	Dune::GeometryType	type,
		Nodes const &...	nodes
	)		const

inlineprotected

Create a quadrature rule using the QuadratureFactory by calculating the quadrature order necessary to integrate the (bi)linear-form accurately.

void setQuadFactory ( PQF && pre )

inline

Create a quadrature factory from a PreQuadratureFactory, e.g. class derived from QuadratureFactory

Template Parameters

PQF	A PreQuadratureFactory
