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.

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.

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 154 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.

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 166 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).
