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 155 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 161 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 166 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 172 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 179 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.
