◆ VectorFieldValue

template<int dim, typename NumberType , typename ExtractorType_Field >

using Differentiation::AD::internal::VectorFieldValue = typedef ScalarFieldGradient<dim, NumberType, ExtractorType_Field>

A helper struct that defines the return type of value computations of vector fields the ExtractorType_Field template parameter.

Definition at line 2336 of file ad_helpers.h.

◆ VectorFieldJacobian

template<int dim, typename NumberType , typename ExtractorType_Field , typename ExtractorType_Derivative >

using Differentiation::AD::internal::VectorFieldJacobian = typedef ScalarFieldHessian<dim, NumberType, ExtractorType_Field, ExtractorType_Derivative>

A helper struct that defines the final return type of Jacobian (first derivative) calculations of vector fields with respect to fields as defined by the two extractor-type template parameters. The first, ExtractorType_Field, defines the field from which the initial field values are computed while the second, ExtractorType_Derivative, defines the field that the derivatives are taken with respect to.

◆ extract_field_component_indices() [1/2]

template<int dim, typename IndexType = unsigned int, typename ExtractorType >

std::vector<IndexType> Differentiation::AD::internal::extract_field_component_indices	(	const ExtractorType &	extractor,
		const bool	ignore_symmetries = `true`
	)

Return a global view of the field component indices that correspond to the input extractor. For this general function the ignore_symmetries flag has no effect.

Definition at line 2367 of file ad_helpers.h.

◆ extract_field_component_indices() [2/2]

template<int dim, typename IndexType = unsigned int>

std::vector<IndexType> Differentiation::AD::internal::extract_field_component_indices	(	const FEValuesExtractors::SymmetricTensor< 2 > &	extractor_symm_tensor,
		const bool	ignore_symmetries = `true`
	)

Return a global view of the field component indices that correspond to the input FEValuesExtractors::SymmetricTensor extractor_symm_tensor. If the ignore_symmetries is set true, then all component of the tensor are considered to be independent. If set to false, then the set of returned indices will contain duplicate entries for components that are symmetric.
