Detailed Description

This namespace defines the copy and set functions used in AlignedVector. These functions operate in parallel when there are enough elements in the vector.

Enumeration Type Documentation

EvaluatorVariant

enum internal::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.

Function Documentation

is_active_iterator()

template<class DI >

bool internal::is_active_iterator ( const DI &  )

inline

Find out if an iterator supports inactive cells.

Definition at line 43 of file loop.h.

maybe_update_jacobian_3rd_derivatives()

template<int dim, int spacedim, typename VectorType , typename DoFHandlerType >

void internal::maybe_update_jacobian_3rd_derivatives	(	const CellSimilarity::Similarity	cell_similarity,
		const typename ::QProjector< dim >::DataSetDescriptor	data_set,
		const typename ::MappingFEField< dim, spacedim, VectorType, DoFHandlerType >::InternalData &	data,
		const FiniteElement< dim, spacedim > &	fe,
		const ComponentMask &	fe_mask,
		const std::vector< unsigned int > &	fe_to_real,
		std::vector< DerivativeForm< 4, dim, spacedim > > &	jacobian_3rd_derivatives
	)

Update the fourth derivative of the transformation from unit to real cell, the Jacobian hessian gradients.

Skip the computation if possible as indicated by the first argument.

Definition at line 911 of file mapping_fe_field.cc.

maybe_update_jacobian_pushed_forward_3rd_derivatives()

template<int dim, int spacedim, typename VectorType , typename DoFHandlerType >

void internal::maybe_update_jacobian_pushed_forward_3rd_derivatives	(	const CellSimilarity::Similarity	cell_similarity,
		const typename ::QProjector< dim >::DataSetDescriptor	data_set,
		const typename ::MappingFEField< dim, spacedim, VectorType, DoFHandlerType >::InternalData &	data,
		const FiniteElement< dim, spacedim > &	fe,
		const ComponentMask &	fe_mask,
		const std::vector< unsigned int > &	fe_to_real,
		std::vector< Tensor< 5, spacedim > > &	jacobian_pushed_forward_3rd_derivatives
	)

Update the fourth derivative of the transformation from unit to real cell, the Jacobian hessian gradients, pushed forward to the real cell coordinates.

Skip the computation if possible as indicated by the first argument.

Definition at line 967 of file mapping_fe_field.cc.

maybe_compute_face_data()

template<int dim, int spacedim, typename VectorType , typename DoFHandlerType >

void internal::maybe_compute_face_data	(	const ::Mapping< dim, spacedim > &	mapping,
		const typename ::Triangulation< dim, spacedim >::cell_iterator &	cell,
		const unsigned int	face_no,
		const unsigned int	subface_no,
		const std::vector< double > &	weights,
		const typename ::MappingFEField< dim, spacedim, VectorType, DoFHandlerType >::InternalData &	data,
		internal::FEValues::MappingRelatedData< dim, spacedim > &	output_data
	)

Depending on what information is called for in the update flags of the data object, compute the various pieces of information that is required by the fill_fe_face_values() and fill_fe_subface_values() functions. This function simply unifies the work that would be done by those two functions.

The resulting data is put into the output_data argument.

Definition at line 1082 of file mapping_fe_field.cc.

do_fill_fe_face_values()

template<int dim, int spacedim, typename VectorType , typename DoFHandlerType >

void internal::do_fill_fe_face_values	(	const ::Mapping< dim, spacedim > &	mapping,
		const typename ::Triangulation< dim, spacedim >::cell_iterator &	cell,
		const unsigned int	face_no,
		const unsigned int	subface_no,
		const typename ::QProjector< dim >::DataSetDescriptor	data_set,
		const Quadrature< dim-1 > &	quadrature,
		const typename ::MappingFEField< dim, spacedim, VectorType, DoFHandlerType >::InternalData &	data,
		const FiniteElement< dim, spacedim > &	fe,
		const ComponentMask &	fe_mask,
		const std::vector< unsigned int > &	fe_to_real,
		internal::FEValues::MappingRelatedData< dim, spacedim > &	output_data
	)

Do the work of MappingFEField::fill_fe_face_values() and MappingFEField::fill_fe_subface_values() in a generic way, using the 'data_set' to differentiate whether we will work on a face (and if so, which one) or subface.

Definition at line 1220 of file mapping_fe_field.cc.

extract_interpolation_matrices()

template<typename DoFHandlerType >

void internal::extract_interpolation_matrices	(	const DoFHandlerType &	,
		::Table< 2, FullMatrix< double > > &
	)

Generate a table that contains interpolation matrices between each combination of finite elements used in a DoFHandler of some kind. Since not all elements can be interpolated onto each other, the table may contain empty matrices for those combinations of elements for which no such interpolation is implemented.
