Detailed Description

template<int dim>
class QuadratureSelector< dim >

This class implements the quadrature rule passed to its constructor as a string. Supported quadratures are QGauss (of all orders), QMidpoint, QMilne, QSimpson, QTrapez and QWeddle.

This class is useful if you want to use flexible quadrature rules, that are read from a parameter file (see ParameterHandler for this).

Constructor & Destructor Documentation

QuadratureSelector()

template<int dim>

QuadratureSelector< dim >::QuadratureSelector	(	const std::string &	s,
		const unsigned int	order = 0
	)

Constructor. Takes the name of the quadrature rule (one of "gauss", "milne", "weddle", etc) and, if it is "gauss", the number of quadrature points in each coordinate direction.

Member Function Documentation

get_quadrature_names()

template<int dim>

std::string QuadratureSelector< dim >::get_quadrature_names ( )

static

This function returns all possible names for quadratures as a list separated by |, so that you can use it for the definition of parameter files (see ParameterHandler for details).

Definition at line 69 of file quadrature_selector.cc.

create_quadrature()

template<int dim>

Quadrature< dim > QuadratureSelector< dim >::create_quadrature ( const std::string &  s, const unsigned int  order  )

staticprivate

This static function creates a quadrature object according to the name given as a string, and the appropriate order (if the name is "gauss"). It is called from the constructor.
