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 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().

◆ append_face_data() [1/2]

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

Definition at line 409 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 417 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.
