Detailed Description

template<int dim>
class QGaussPyramid< dim >

Integration rule for pyramid entities.

Member Typedef Documentation

◆ SubQuadrature

template<int dim>

using Quadrature< dim >::SubQuadrature = Quadrature<dim - 1>

inherited

Define an alias for a quadrature that acts on an object of one dimension less. For cells, this would then be a face quadrature.

Definition at line 90 of file quadrature.h.

Constructor & Destructor Documentation

◆ QGaussPyramid()

template<int dim>

QGaussPyramid< dim >::QGaussPyramid ( const unsigned int n_points_1D )

explicit

Users specify a number n_points_1D as an indication of what polynomial degree to be integrated exactly. For details, see the comments of QGaussSimplex.

Definition at line 1756 of file quadrature_lib.cc.

Member Function Documentation

◆ operator==()

template<int dim>

bool Quadrature< dim >::operator== ( const Quadrature< dim > & p ) const

inherited

Test for equality of two quadratures.

Definition at line 302 of file quadrature.cc.

◆ initialize()

template<int dim>

void Quadrature< dim >::initialize	(	const std::vector< Point< dim > > &	points,
		const std::vector< double > &	weights
	)

inherited

Set the quadrature points and weights to the values provided in the arguments.

Definition at line 50 of file quadrature.cc.

◆ size()

template<int dim>

unsigned int Quadrature< dim >::size ( ) const

inherited

Number of quadrature points.

◆ point()

template<int dim>

const Point< dim > & Quadrature< dim >::point ( const unsigned int i ) const

inherited

Return the ith quadrature point.

◆ get_points()

template<int dim>

const std::vector< Point< dim > > & Quadrature< dim >::get_points ( ) const

inherited

Return a reference to the whole array of quadrature points.

◆ weight()

template<int dim>

double Quadrature< dim >::weight ( const unsigned int i ) const

inherited

Return the weight of the ith quadrature point.

◆ get_weights()

template<int dim>

const std::vector< double > & Quadrature< dim >::get_weights ( ) const

inherited

Return a reference to the whole array of weights.

◆ memory_consumption()

template<int dim>

std::size_t Quadrature< dim >::memory_consumption

inherited

Determine an estimate for the memory consumption (in bytes) of this object.

Definition at line 311 of file quadrature.cc.

◆ serialize()

template<int dim>

template<class Archive >

void Quadrature< dim >::serialize	(	Archive &	ar,
		const unsigned int	version
	)

inherited

Write or read the data of this object to or from a stream for the purpose of serialization using the BOOST serialization library.

◆ is_tensor_product()

template<int dim>

bool Quadrature< dim >::is_tensor_product ( ) const

inherited

This function returns true if the quadrature object is a tensor product of one-dimensional formulas and the quadrature points are sorted lexicographically.

◆ get_tensor_basis()

template<int dim>

std::conditional< dim==1, std::array< Quadrature< 1 >, dim >, conststd::array< Quadrature< 1 >, dim > & >::type Quadrature< dim >::get_tensor_basis

inherited

In case the quadrature formula is a tensor product, this function returns the dim one-dimensional basis objects. Otherwise, calling this function is not allowed.

For dim equal to one, we can not return the std::array as a const reference and have to return it by value. In this case, the array will always contain a single element (this).

Note: The actual return type of this function is
std::conditional<dim == 1,

std::array<Quadrature<1>, dim>,

const std::array<Quadrature<1>, dim> &>::type

The type is abbreviated in the online documentation to improve readability of this page.

Definition at line 323 of file quadrature.cc.

Member Data Documentation

◆ quadrature_points

template<int dim>

std::vector<Point<dim> > Quadrature< dim >::quadrature_points

protectedinherited

List of quadrature points. To be filled by the constructors of derived classes.

Definition at line 283 of file quadrature.h.

◆ weights

template<int dim>

std::vector<double> Quadrature< dim >::weights

protectedinherited

List of weights of the quadrature points. To be filled by the constructors of derived classes.

Definition at line 289 of file quadrature.h.

◆ is_tensor_product_flag

template<int dim>

bool Quadrature< dim >::is_tensor_product_flag

protectedinherited

Indicates if this object represents quadrature formula that is a tensor product of one-dimensional formulas. This flag is set if dim==1 or the constructors taking a Quadrature<1> (and possibly a Quadrature<dim-1> object) is called. This implies that the quadrature points are sorted lexicographically.

Definition at line 298 of file quadrature.h.

◆ tensor_basis

template<int dim>

std::unique_ptr<std::array<Quadrature<1>, dim> > Quadrature< dim >::tensor_basis

protectedinherited

Stores the one-dimensional tensor basis objects in case this object can be represented by a tensor product.
