Member Function Documentation

◆ initialize()

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

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

◆ memory_consumption()

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

Returns the memory consumption in bytes.

Member Data Documentation

◆ n_q_points

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

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

Definition at line 146 of file mapping_info.h.

◆ quadrature_1d

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

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

Definition at line 152 of file mapping_info.h.

◆ quadrature

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

Quadrature formula applied on the given cell or face.

Definition at line 157 of file mapping_info.h.

◆ tensor_quadrature_weights

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

Quadrature weights separated by dimension for use in specific situations.

Definition at line 163 of file mapping_info.h.

◆ quadrature_weights

template<int structdim, int spacedim, typename Number , typename VectorizedArrayType >
AlignedVector<Number> internal::MatrixFreeFunctions::MappingInfoStorage< structdim, spacedim, Number, VectorizedArrayType >::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).

Definition at line 170 of file mapping_info.h.

◆ face_orientations

template<int structdim, int spacedim, typename Number , typename VectorizedArrayType >
::Table<2, unsigned int> internal::MatrixFreeFunctions::MappingInfoStorage< structdim, spacedim, Number, VectorizedArrayType >::QuadratureDescriptor::face_orientations

For quadrature on faces, the evaluation of basis functions is not in the correct order if a face is not in the standard orientation to a given element. This data structure is used to re-order the data evaluated on quadrature points to represent the correct order.
