Detailed Description

Class representing a quadrature factory, that holds information about cells on which generalized duffy quadrature should be applied.

On all other cells tensored integration rules are setted. Therefore derived methods only applicate on cells with tensored structur. The cells with setted duffy integration rule are controlled via the addSingularPoint routine.

A cell should at most have one duffy quadrature rule, else an assertion will be thrown while application.

If no information for singular points is added, this class simplifies to the QuadRuleFactoryTensor.

Constructor & Destructor Documentation

QuadRuleFactoryTensorDuffy2d()

concepts::QuadRuleFactoryTensorDuffy2d::QuadRuleFactoryTensorDuffy2d	(	enum intRule	tensorType = GAUSS_JACOBI,
		uint	constPointsT = 10,
		uint	addPointsT = 2,
		bool	constantT = false
	)

Constructor setting the information for the tensor quadrature.

To this point no singularity information is applied.

Member Function Documentation

addSingularPoint()

void concepts::QuadRuleFactoryTensorDuffy2d::addSingularPoint ( const uint  vAttr, const Real  beta, uint  npx = 20, uint  npy = 20  )

inline

Adds information for a given singularity vertex attribute, and specified duffy quadrature on it. If information for given vertex attribute was already added, the last information added is valid.

Parameters

vAttr	attribute of the singular vertex
beta	duffy transformation parameter
npx	number of quadrature points of underlying tensor quadrature in x-direction
npy	number of quadrature points of underlying tensor quadrature in y-direction

Definition at line 714 of file quadRule.hh.

count()

const uint concepts::QuadRuleFactoryTensor2d::count ( ) const

inlineinherited

Returns counter of changes.

Definition at line 615 of file quadRule.hh.

info()

virtual std::ostream & concepts::QuadRuleFactoryTensorDuffy2d::info ( std::ostream &  os ) const

protectedvirtual

Returns information in an output stream.

Reimplemented from concepts::QuadRuleFactoryTensor2d.

integrationRule()

virtual const std::string concepts::QuadRuleFactoryTensorDuffy2d::integrationRule ( ) const

virtual

Returns information on the settings of the quadrature rule.

Reimplemented from concepts::QuadRuleFactoryTensor2d.

operator()()

virtual QuadratureRule2d * concepts::QuadRuleFactoryTensorDuffy2d::operator() ( const concepts::QuadNd &  cell, const ushort *  p  ) const

virtual

Application operator that returns setted integration rule on a given cell for requested polynomial degree.

If a cell has two setted singular vertices, which information was added to the factory, an assertion is stated.

Reimplemented from concepts::QuadRuleFactoryTensor2d.

setTensor()

virtual void concepts::QuadRuleFactoryTensor2d::setTensor ( enum concepts::intRule  rule, bool  constant, uint  points  )

virtualinherited

Sets the integration rule for cells with tensor 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::QuadRuleFactoryTensor2d::type ( ) const

inlineinherited

Returns the integration type.

Member Data Documentation

addNumberOfPoints_

uint concepts::QuadRuleFactoryTensor2d::addNumberOfPoints_

protectedinherited

Number of integration points to add to approximation order when varying number of integration points is requested. Default is 2.

Definition at line 642 of file quadRule.hh.

cnt_

uint concepts::QuadRuleFactoryTensor2d::cnt_

protectedinherited

Counter for changes.

Definition at line 649 of file quadRule.hh.

constNumerOfPoints_

uint concepts::QuadRuleFactoryTensor2d::constNumerOfPoints_

protectedinherited

Number of integration points to use when constant number is requested. Default value is 10.

Definition at line 638 of file quadRule.hh.

integrationType_

enum intRule concepts::QuadRuleFactoryTensor2d::integrationType_

protectedinherited

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 634 of file quadRule.hh.

useConstantNumberOfPoints_

bool concepts::QuadRuleFactoryTensor2d::useConstantNumberOfPoints_

protectedinherited

Use constant number of integration points (true) or not (false). Default is false (ie. varying number of points).

Definition at line 646 of file quadRule.hh.

vtxData_

concepts::HashMap<DuffyData> concepts::QuadRuleFactoryTensorDuffy2d::vtxData_
