Definition at line 94 of file dof_accessor_set.cc.

Enumeration Type Documentation

◆ EigenvalueAlgorithm

An enum to define the available types of eigenvalue estimation algorithms.

Enumerator
lanczos 

This option runs the conjugate gradient solver and computes an eigenvalue estimation from the underlying Lanczos space. This only works for symmetric positive definite matrices.

power_iteration 

This option runs a power iteration to estimate the largest eigenvalue. This algorithm also works for non-symmetric matrices, but typically gives less accurate estimates than the option 'lanczos' for the same number of iterations because it does not take the relation between vectors in the iterations into account (roughly speaking the off-diagonal entries in the tri-diagonal matrix of the Lanczos iteration).

Definition at line 67 of file precondition.h.

◆ FEEvaluationImplHangingNodesRunnerTypes

Enumerator
scalar 
vectorized 

Definition at line 40 of file evaluation_kernels_hanging_nodes.h.

◆ VectorizationTypes

Helper enum to specify the type of vectorization for FEEvaluationImplHangingNodesRunnerTypes::scalar.

Enumerator
index 

Process cell by cell.

group 

Process cells with the same refinement configuration together.

mask 

Like index but without access to individual lanes and instead use masks with a single entry with the value one.

sorted 

Assume that all lanes have the same refinement configuration.

Definition at line 52 of file evaluation_kernels_hanging_nodes.h.

◆ HelperType

Helper enum to specify which Helper implementation should be used.

Enumerator
constant 

Compute the start indices of faces and edges based on the template argument fe_degree.

dynamic 

Compute the start indices of faces and edges based on the fe_degree passed to the constructor (to be used if the template argument is -1).

Definition at line 1109 of file evaluation_kernels_hanging_nodes.h.

◆ EvaluatorVariant

In this namespace, the evaluator routines that evaluate the tensor products are implemented.

Enumerator
evaluate_general 

Do not use anything more than the tensor product structure of the finite element.

evaluate_symmetric 

Perform evaluation by exploiting symmetry in the finite element: i.e., skip some computations by utilizing the symmetry in the shape functions and quadrature points.

evaluate_evenodd 

Use symmetry to apply the operator to even and odd parts of the input vector separately: see the documentation of the EvaluatorTensorProduct specialization for more information.

evaluate_symmetric_hierarchical 

Use symmetry in Legendre and similar polynomial spaces where the shape functions with even number are symmetric about the center of the quadrature points (think about even polynomial degrees) and the shape functions with odd number are anti-symmetric about the center of the quadrature points (think about odd polynomial degrees). This allows to use a strategy similar to the even-odd technique but without separate coefficient arrays. See the documentation of the EvaluatorTensorProduct specialization for more information.

Definition at line 37 of file tensor_product_kernels.h.

◆ EvaluatorQuantity

Determine which quantity should be computed via the tensor product kernels.

Enumerator
value 

Evaluate/integrate by shape functions.

gradient 

Evaluate/integrate by gradients of the shape functions.

hessian 

Evaluate/integrate by hessians of the shape functions.

Definition at line 74 of file tensor_product_kernels.h.

Function Documentation

◆ create_higher_dim_point()

template<int dim>
Point< dim+1 > internal::create_higher_dim_point ( const Point< dim > &  point,
const unsigned int  component_in_dim_plus_1,
const double  coordinate_value 
)
private

Creates a (dim + 1)-dimensional point by copying over the coordinates of the incoming dim-dimensional point and setting the "missing" (dim + 1)-dimensional component to the incoming coordinate value.

For example, given the input \(\{(x, y), 2, z \}\) this function creates the point \((x, y, z)\).

The coordinates of the dim-dimensional point are written to the coordinates of the (dim + 1)-dimensional point in the order of the convention given by the function coordinate_to_one_dim_higher. Thus, the order of coordinates on the lower-dimensional point are not preserved: \(\{(z, x), 1, y \}\) creates the point \((x, y, z)\).

Definition at line 23 of file function_restriction.cc.

◆ ensure_kokkos_initialized()

void internal::ensure_kokkos_initialized ( )

Makes sure that Kokkos is initialized. Sets dealii_initialized_kokkos.

Definition at line 30 of file kokkos.cc.

◆ expand()

internal::GenericDoFsPerObject internal::expand ( const unsigned int  dim,
const std::vector< unsigned int > &  dofs_per_object,
const ReferenceCell  reference_cell 
)

Utility function to convert "dofs per object" information of a dim dimensional reference cell reference_cell.

Definition at line 24 of file fe_data.cc.

◆ make_reference_cell_from_int()

constexpr ReferenceCell internal::make_reference_cell_from_int ( const std::uint8_t  kind)
inlineconstexpr

A helper function to create a ReferenceCell object from an integer. ReferenceCell objects are "singletons" (actually, "multitons" – there are multiple, but they are only a handful and these are all that can be used). What is then necessary is to have a way to create these with their internal id to distinguish the few possible ones in existence. We could do this via a public constructor of ReferenceCell, but that would allow users to create ones outside the range we envision, and we don't want to do that. Rather, the constructor that takes an integer is made private but we have this one function in an internal namespace that is a friend of the class and can be used to create the objects.

Definition at line 1056 of file reference_cell.h.

◆ combined_face_orientation()

◆ split_face_orientation()

inline

Definition at line 45 of file tria_orientation.h.

void internal::evaluate_gradients_collocation ( const MatrixFreeFunctions::UnivariateShapeData< Number2 > &  shape,
const Number *  values,

std::enable_if_t<(variant==evaluate_general), void > internal::apply_matrix_vector_product ( const Number2 *  matrix,
const Number *  in,

)

One-dimensional kernel for use by the generic tensor product interpolation as provided by the class EvaluatorTensorProduct, implementing a matrix-vector product along this dimension, controlled by the number of rows and columns and the stride in the input and output arrays, which are embedded into some lexicographic ordering of unknowns in a tensor-product arrangement.

Besides this generic function for templated loop lengths, there are several specializations of this class to account for run-time matrix sizes as well as some symmetries that reduce the data access or arithmetic operations. The specializations are technically realized by conditional function overloading with std::enable_if_t based on the first template parameter.

Internal evaluator specialized for "symmetric" finite elements in the evenodd matrix format.

This function implements a different approach to the symmetric case for values, gradients, and Hessians as in the above matrices: It is possible to reduce the cost per dimension from N^2 to N^2/2, where N is the number of 1d dofs (there are only N^2/2 different entries in the shape matrix, so this is plausible). The approach is based on the idea of applying the operator on the even and odd part of the input vectors separately, given that the basis of shape functions evaluated at quadrature points is symmetric. This method is presented e.g. in the book "Implementing Spectral Methods for Partial Differential Equations" by David A. Kopriva, Springer, 2009, section 3.5.3 (Even-Odd-Decomposition). Even though the experiments in the book say that the method is not efficient for N<20, it is more efficient in the context where the loop bounds are compile-time constants (templates).

)

Internal evaluator specialized for "symmetric" finite elements in the symmetric_hierarchical matrix format.

This class implements an approach similar to the even-odd decomposition but with a different type of symmetry. In this case, we assume that a single shape function already shows the symmetry over the quadrature points, rather than the complete basis that is considered in the even-odd case. In particular, we assume that the shape functions are ordered as in the Legendre basis, with symmetric shape functions in the even slots (rows of the values array) and point-symmetric in the odd slots. Like the even-odd decomposition, the number of operations are N^2/2 rather than N^2 FMAs (fused multiply-add), where N is the number of 1d dofs. The difference is in the way the input and output quantities are symmetrized.

const int  n_rows_runtime = 0,
const int  stride_runtime = 1 
)
inline

This function applies the tensor product operation to produce face values from cell values. The algorithm involved here can be interpreted as the first sweep in sum factorization, reducing the dimensionality of the data set from dim-dimensional cell values to (dim-1)-dimensional face values. This step is always done before we evaluate within the face, as it reduces the length of the loops for the successive steps.

Template Parameters
n_rows_templateThe number of entries within the interpolation, typically equal to the polynomial degree plus one, if known at compile time, otherwise n_rows_runtime is used.
stride_templateThe stride between successive entries in the one-dimensional operation of sum factorization, if known at compile time, otherwise stride_runtime is used.
contract_onto_faceIf true, the input vector is of size n_rows^dim and interpolation into n_rows^(dim-1) points is performed. This is a typical scenario in FEFaceEvaluation::evaluate() calls. If false, data from n_rows^(dim-1) points is expanded into the n_rows^dim points of the higher-dimensional data array. Derivatives in the case contract_onto_face==false are summed together.
addIf true, the result is added to the output vector, else the computed values overwrite the content in the output.
max_derivativeSets the number of derivatives that should be computed. 0 means only values, 1 means values and first derivatives, 2 up to second derivates. Note that all the derivatives access the data in shape_values passed to the constructor of the class.
Parameters
shape_valuesAddress of the interpolation matrix.
n_blocksNumber of interpolation layers used along the up to two dimensions tangential to the interpolation direction.
stepsIncrements in the input array from one step to the next, varied in conjunction with the stride_template variable: We increment by stride_template along the 1d interpolation, and then increment by steps when passing from one line to the next.
inputAddress of the input data vector.
outputAddress of the output data vector.
n_rows_runtimeAlternative number of rows to be used if the variable n_rows_template is 0, enabling a run-time path.
stride_runtimeAlternative number for the stride to be used if the variable n_rows_template is 0.

Compute the polynomial interpolation of a tensor product shape function \(\varphi_i\) given a vector of coefficients \(u_i\) in the form \(u_h(\mathbf{x}) = \sum_{i=1}^{k^d} \varphi_i(\mathbf{x}) u_i\). The shape functions \(\varphi_i(\mathbf{x}) = \prod_{d=1}^{\text{dim}}\varphi_{i_d}^\text{1d}(x_d)\) represent a tensor product. The function returns a pair with the value of the interpolation as the first component and the gradient in reference coordinates as the second component. Note that for compound types (e.g. the values field begin a Point<spacedim> argument), the components of the gradient are sorted as Tensor<1, dim, Tensor<1, spacedim>> with the derivatives as the first index; this is a consequence of the generic arguments in the function.

Parameters
polyThe underlying one-dimensional polynomial basis \(\{\varphi^{1d}_{i_1}\}\) given as a vector of polynomials.
valuesThe expansion coefficients \(u_i\) of type Number in the polynomial interpolation. The coefficients can be simply double variables but e.g. also Point<spacedim> in case they define arithmetic operations with the type Number2.
pThe position in reference coordinates where the interpolation should be evaluated.
d_linearFlag to specify whether a d-linear (linear in 1d, bi-linear in 2d, tri-linear in 3d) interpolation should be made, which allows to unroll loops and considerably speed up evaluation.
renumberOptional parameter to specify a renumbering in the coefficient vector, assuming that values[renumber[i]] returns the lexicographic (tensor product) entry of the coefficients. If the vector is entry, the values are assumed to be sorted lexicographically.

In the set_dof_values(), we need to invoke abs() also on unsigned data types, which is ill-formed on newer C++ standards. To avoid this, we use std::abs on default types, but simply return the number on unsigned types.

◆ is_supported_operation

template<template< class... > class Op, class... Args>
constexpr bool internal::is_supported_operation
constexpr
Initial value:
=
SupportsOperation::is_detected<Op, Args...>::value

A constexpr variable that describes whether or not Op<Args...> is a valid expression.

The way this is used is to define an Op operation template that describes the operation we want to perform, and Args is a template pack that describes the arguments to the operation. This variable then states whether the operation, with these arguments, leads to a valid C++ expression.

An example is if one wanted to find out whether a type T has a get_mpi_communicator() member function. In that case, one would write the operation as

template <typename T>
= decltype(std::declval<T>().get_mpi_communicator());

and could define a variable like

template <typename T>
constexpr bool has_get_mpi_communicator =

The trick used here is that get_mpi_communicator_op is a general template, but when used with a type that does not have a get_mpi_communicator() member variable, the decltype(...) operation will fail because its argument does not represent a valid expression for such a type. In other words, for such types T that do not have such a member function, the general template get_mpi_communicator_op represents a valid declaration, but the instantiation get_mpi_communicator_op<T> is not, and the variable declared here detects and reports this.
