Detailed Description

template<class Imp, class... LF>
class AMDiS::VariadicGridFunctionLocalOperator< Imp, LF >

A LocalOperator parametrized by multiple LocalFunctions.

A LocalOperator that takes multiple LocalFunctions as coefficient. Provides quadrature rules and passes the LocalFunctions, bound to an element, to the assemble method of an implementation class.

The class implements the interface of a LocalOperator.

Template Parameters

LF	The class types of the LocalFunctions
Imp	Class providing the local assembling method

Requirements:

• Each LF models the Concepts::LocalFunction

Constructor & Destructor Documentation

VariadicGridFunctionLocalOperator()

template<class Imp , class... LF>

template<class... LocalFct, class Impl >

VariadicGridFunctionLocalOperator ( Impl &&  impl, int  derivDeg, int  localFctOrder, LocalFct &&...  localFct  )

inline

Constructor. Stores a copy of localFct and impl.

A VariadicGridFunctionLocalOperator takes multiple LocalFunctions, an implementation class, the differentiation order of the operator and a user-provided polynomial degree, used as the degree of the LocalFunction to calculate the quadrature degree of the operator. Usually this should be the maximum of the degrees of the localFcts. If localFctOrder is -1, we try to detect the maximum polynomial degree from the local function implementations.

Member Function Documentation

assemble() [1/2]

template<class Imp , class... LF>

template<class CG , class Node , class Vec >

void assemble ( CG const &  contextGeo, Node const &  node, Vec &  elementVector  ) const

inline

Assemble a local element vector on the element that is bound.

This function calls the assemble method from the impl_ class and additionally passes a quadrature rule and the localFct_ to that method.

assemble() [2/2]

template<class Imp , class... LF>

template<class CG , class RN , class CN , class Mat >

void assemble ( CG const &  contextGeo, RN const &  rowNode, CN const &  colNode, Mat &  elementMatrix  ) const

inline

Assemble a local element matrix on the element that is bound.

This function calls the assemble method from the impl_ class and additionally passes a quadrature rule and the localFct_ to that method.

bind()

template<class Imp , class... LF>

template<class Element >

void bind ( Element const &  element )

inline

Binds operator to element.

Binds all local functions in localFct_ to the element.
