The class that stores the shape functions, gradients and Hessians evaluated for a tensor product finite element and tensor product quadrature formula on the unit cell. Because of this structure, only one-dimensional data is stored.

internal::MatrixFreeFunctions::ShapeInfo< Number >::ShapeInfo | ( | ) |
Empty constructor. Does nothing.

void internal::MatrixFreeFunctions::ShapeInfo< Number >::reinit | ( | const Quadrature< 1 > & | quad, |
const FiniteElement< dim > & | fe_dim | ||
) |
Initializes the data fields. Takes a one-dimensional quadrature formula and a finite element as arguments and evaluates the shape functions, gradients and Hessians on the one-dimensional unit cell. This function assumes that the finite element is derived from a one-dimensional element by a tensor product and that the zeroth shape function in zero evaluates to one.

std::size_t internal::MatrixFreeFunctions::ShapeInfo< Number >::memory_consumption | ( | ) | const |
Returns the memory consumption of this class in bytes.

AlignedVector<VectorizedArray<Number> > internal::MatrixFreeFunctions::ShapeInfo< Number >::shape_values |
Stores the shape values of the 1D finite element evaluated on all 1D quadrature points in vectorized format, i.e., as an array of VectorizedArray<dim>::n_array_elements equal elements. The length of this array is n_dofs_1d * n_q_points_1d
and quadrature points are the index running fastest.

AlignedVector<VectorizedArray<Number> > internal::MatrixFreeFunctions::ShapeInfo< Number >::shape_gradients |
Stores the shape gradients of the 1D finite element evaluated on all 1D quadrature points in vectorized format, i.e., as an array of VectorizedArray<dim>::n_array_elements equal elements. The length of this array is n_dofs_1d * n_q_points_1d
and quadrature points are the index running fastest.

AlignedVector<VectorizedArray<Number> > internal::MatrixFreeFunctions::ShapeInfo< Number >::shape_hessians |
Stores the shape Hessians of the 1D finite element evaluated on all 1D quadrature points in vectorized format, i.e., as an array of VectorizedArray<dim>::n_array_elements equal elements. The length of this array is n_dofs_1d * n_q_points_1d
and quadrature points are the index running fastest.

Table<2,unsigned int> internal::MatrixFreeFunctions::ShapeInfo< Number >::face_indices |
Stores the indices from cell DoFs to face DoFs. The rows go through the 2*dim
faces, and the columns the DoFs on the faces.
Definition at line 115 of file shape_info.h.
std::vector<Number> internal::MatrixFreeFunctions::ShapeInfo< Number >::face_value[2] |
Stores one-dimensional values of shape functions evaluated in zero and one, i.e., on the one-dimensional faces. Not vectorized.
Definition at line 121 of file shape_info.h.
std::vector<Number> internal::MatrixFreeFunctions::ShapeInfo< Number >::face_gradient[2] |
Stores one-dimensional gradients of shape functions evaluated in zero and one, i.e., on the one-dimensional faces. Not vectorized.
Definition at line 127 of file shape_info.h.
std::vector<Number> internal::MatrixFreeFunctions::ShapeInfo< Number >::subface_value[2] |
Stores one-dimensional values of shape functions on subface. Since there are two subfaces, store two variants. Not vectorized.
Definition at line 133 of file shape_info.h.
std::vector<Number> internal::MatrixFreeFunctions::ShapeInfo< Number >::shape_values_number |
Non-vectorized version of shape values. Needed when evaluating face info.
Definition at line 139 of file shape_info.h.
std::vector<Number> internal::MatrixFreeFunctions::ShapeInfo< Number >::shape_gradient_number |
Non-vectorized version of shape gradients. Needed when evaluating face info.

unsigned int internal::MatrixFreeFunctions::ShapeInfo< Number >::dofs_per_cell |
Stores the number of DoFs per cell in dim
dimensions.

unsigned int internal::MatrixFreeFunctions::ShapeInfo< Number >::n_q_points_face |
Stores the number of quadrature points per face in dim
dimensions.
Definition at line 164 of file shape_info.h.
unsigned int internal::MatrixFreeFunctions::ShapeInfo< Number >::dofs_per_face |
Stores the number of DoFs per face in dim
dimensions.
