Detailed Description

Class for creation of a quadrature rule.

There is possiblity to specify a constant number of points or a number dependent from a maximal polynomial degree.

Definition at line 224 of file quadRule.hh.

Constructor & Destructor Documentation

QuadRuleFactory()

concepts::QuadRuleFactory::QuadRuleFactory	(	enum intRule	type = GAUSS_JACOBI,
		uint	constPoints = 10,
		uint	addPoints = 2,
		bool	constant = false
	)

Member Function Documentation

count()

const uint concepts::QuadRuleFactory::count ( ) const

inline

Returns counter of changes.

Definition at line 249 of file quadRule.hh.

info()

virtual std::ostream& concepts::QuadRuleFactory::info ( std::ostream &  os ) const

protectedvirtual

Returns information in an output stream.

Reimplemented from concepts::OutputOperator.

integrationRule()

const std::string concepts::QuadRuleFactory::integrationRule

(

)

const

Returns information on the settings of the quadrature rule.

operator()()

QuadratureRule1d* concepts::QuadRuleFactory::operator()

(

const ushort

p = 1

)

const

Returns the quadrature rule, i.e.

pre-computed abscissas and weights.

Created dynamically and has to be deleted by the user.

Parameters

p	maximal polynomial degree

reset()

void concepts::QuadRuleFactory::reset

(

)

Set the standard type of integration.

set()

void concepts::QuadRuleFactory::set	(	enum concepts::intRule	rule,
		bool	constant,
		uint	points
	)

Sets the integration rule.

Parameters

rule	Type of integration
constant	Flag, true = constant number of points
points	Number of points, constant or to add

type()

enum intRule concepts::QuadRuleFactory::type ( ) const

inline

Returns the integration type.

Member Data Documentation

addNumberOfPoints_

uint concepts::QuadRuleFactory::addNumberOfPoints_

private

Number of integration points to add to approximation order when varying number of integration points is requested.

Default is 2.

Definition at line 273 of file quadRule.hh.

cnt_

uint concepts::QuadRuleFactory::cnt_

private

Counter for changes.

Definition at line 280 of file quadRule.hh.

constNumerOfPoints_

uint concepts::QuadRuleFactory::constNumerOfPoints_

private

Number of integration points to use when constant number is requested.

Default value is 10.

Definition at line 269 of file quadRule.hh.

integrationType_

enum intRule concepts::QuadRuleFactory::integrationType_

private

Default behaviour: integration rule Gauss Jacobi (highest order).

The default value is 4 (Gauss Jacobi). Other possible values are 0 (Gauss Lobatto) for better graphics (connected elements). Use setIntegrationRule() to change it.

Definition at line 257 of file quadRule.hh.

useConstantNumberOfPoints_

bool concepts::QuadRuleFactory::useConstantNumberOfPoints_

private

Use constant number of integration points (true) or not (false).

Default is false (ie. varying number of points).
