Function Documentation

distributed_compute_point_locations()

template<int dim, int spacedim>

DistributedComputePointLocationsInternal< dim, spacedim > GridTools::internal::distributed_compute_point_locations	(	const GridTools::Cache< dim, spacedim > &	cache,
		const std::vector< Point< spacedim > > &	points,
		const std::vector< std::vector< BoundingBox< spacedim > > > &	global_bboxes,
		const std::vector< bool > &	marked_vertices,
		const double	tolerance,
		const bool	perform_handshake,
		const bool	enforce_unique_mapping = false
	)

A function that fills DistributedComputePointLocationsInternal. If the input argument perform_handshake is set to false only the fields needed by GridTools::internal::distributed_compute_point_locations() are filled. If the input argument is set to true additional data structures are set up to be able to set up the communication pattern within Utilities::MPI::RemotePointEvaluation::reinit().

distributed_compute_intersection_locations()

template<int structdim, int dim, int spacedim>

DistributedComputeIntersectionLocationsInternal< structdim, spacedim > GridTools::internal::distributed_compute_intersection_locations	(	const Cache< dim, spacedim > &	cache,
		const std::vector< std::vector< Point< spacedim > > > &	intersection_requests,
		const std::vector< std::vector< BoundingBox< spacedim > > > &	global_bboxes,
		const std::vector< bool > &	marked_vertices,
		const double	tolerance
	)

A function that fills DistributedComputeIntersectionLocationsInternal. intersection_requests are vertices of cells which describe the entities we want to search intersections for. The template parameter structdim provides the dimension of the resulting intersection.

append_face_data() [1/2]

void GridTools::internal::append_face_data ( const CellData< 1 > &  face_data, SubCellData &  subcell_data  )

inline

Definition at line 432 of file grid_tools.cc.

append_face_data() [2/2]

void GridTools::internal::append_face_data ( const CellData< 2 > &  face_data, SubCellData &  subcell_data  )

inline

Definition at line 440 of file grid_tools.cc.

laplace_solve()

void GridTools::internal::laplace_solve ( const SparseMatrix< double > &  S, const AffineConstraints< double > &  constraints, Vector< double > &  u  )

inline

Solve the Laplace equation for the laplace_transform function for one of the dim space dimensions. Factorized into a function of its own in order to allow parallel execution.

compare_point_association()

template<int spacedim>

bool GridTools::internal::compare_point_association	(	const unsigned int	a,
		const unsigned int	b,
		const Tensor< 1, spacedim > &	point_direction,

set_subdomain_id_in_zorder_recursively()

template<class IT >

void GridTools::internal::set_subdomain_id_in_zorder_recursively	(	IT	cell,
		unsigned int &	current_proc_idx,
		unsigned int &	current_cell_idx,
		const unsigned int	n_active_cells,

guess_owners_of_entities()

template<int spacedim, typename T >

std::tuple< std::vector< unsigned int >, std::vector< unsigned int >, std::vector< unsigned int > > GridTools::internal::guess_owners_of_entities	(	const MPI_Comm	comm,
		const std::vector< std::vector< BoundingBox< spacedim > > > &	global_bboxes,
		const std::vector< T > &	entities,
		const double	tolerance
	)

Determine for each rank which entry of entities it might own. The first entry of the returned tuple is a list of ranks and the second and third entry give CRS data structure (pointers within a list of indices).

template<int dim, int spacedim>

std::vector< std::pair< typename Triangulation< dim, spacedim >::active_cell_iterator, Point< dim > > > GridTools::internal::find_all_locally_owned_active_cells_around_point	(	const Cache< dim, spacedim > &	cache,
