Member Typedef Documentation

◆ ScalarNumber

template<int structdim, int spacedim, typename Number >
using internal::MatrixFreeFunctions::MappingInfoStorage< structdim, spacedim, Number >::QuadratureDescriptor::ScalarNumber = typename VectorizedArrayTrait<Number>::value_type

In case this class is instantiated for VectorizedArray types, this indicates the underlying scalar type for data which is the same on all lanes like the quadrature weights.

Definition at line 122 of file mapping_info_storage.h.

Constructor & Destructor Documentation

◆ QuadratureDescriptor()

template<int structdim, int spacedim, typename Number >
internal::MatrixFreeFunctions::MappingInfoStorage< structdim, spacedim, Number >::QuadratureDescriptor::QuadratureDescriptor ( )

Constructor. Does nothing.

Member Function Documentation

◆ initialize() [1/2]

template<int structdim, int spacedim, typename Number >
template<int dim_q>
void internal::MatrixFreeFunctions::MappingInfoStorage< structdim, spacedim, Number >::QuadratureDescriptor::initialize ( const Quadrature< dim_q > &  quadrature)

Set up the lengths in the various members of this struct.

◆ initialize() [2/2]

template<int structdim, int spacedim, typename Number >
void internal::MatrixFreeFunctions::MappingInfoStorage< structdim, spacedim, Number >::QuadratureDescriptor::initialize ( const Quadrature< 1 > &  quadrature_1d)

Set up the lengths in the various members of this struct.

◆ memory_consumption()

template<int structdim, int spacedim, typename Number >
std::size_t internal::MatrixFreeFunctions::MappingInfoStorage< structdim, spacedim, Number >::QuadratureDescriptor::memory_consumption ( ) const

Returns the memory consumption in bytes.

Member Data Documentation

◆ n_q_points

template<int structdim, int spacedim, typename Number >
unsigned int internal::MatrixFreeFunctions::MappingInfoStorage< structdim, spacedim, Number >::QuadratureDescriptor::n_q_points

Number of quadrature points applied on the given cell or face.

Definition at line 151 of file mapping_info_storage.h.

◆ quadrature_1d

template<int structdim, int spacedim, typename Number >
Quadrature<1> internal::MatrixFreeFunctions::MappingInfoStorage< structdim, spacedim, Number >::QuadratureDescriptor::quadrature_1d

Original one-dimensional quadrature formula applied on the given cell or face.

Definition at line 157 of file mapping_info_storage.h.

◆ quadrature

template<int structdim, int spacedim, typename Number >
Quadrature<structdim> internal::MatrixFreeFunctions::MappingInfoStorage< structdim, spacedim, Number >::QuadratureDescriptor::quadrature

Quadrature formula applied on the given cell or face.

Definition at line 162 of file mapping_info_storage.h.

◆ tensor_quadrature_weights

template<int structdim, int spacedim, typename Number >
std::array<AlignedVector<ScalarNumber>, structdim> internal::MatrixFreeFunctions::MappingInfoStorage< structdim, spacedim, Number >::QuadratureDescriptor::tensor_quadrature_weights

Quadrature weights separated by dimension for use in specific situations.

Definition at line 169 of file mapping_info_storage.h.

◆ quadrature_weights

template<int structdim, int spacedim, typename Number >
AlignedVector<ScalarNumber> internal::MatrixFreeFunctions::MappingInfoStorage< structdim, spacedim, Number >::QuadratureDescriptor::quadrature_weights

A cached vector of quadrature weights in the given number format (non-vectorized, as it is cheap to broadcast the value to all lanes when it is used in a vectorized context).
