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 setup the communication pattern within Utilities::MPI::RemotePointEvaluation::reinit().

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.
