◆ cell_indices()

template<int dim, int spacedim>
std_cxx20::ranges::iota_view< unsigned int, unsigned int > Utilities::MPI::RemotePointEvaluation< dim, spacedim >::CellData::cell_indices ( ) const

Return an object that can be thought of as an array containing all indices from zero (inclusive) to the total number of cells where points reside given by cells.size() (exclusive). This allows one to write code using range-based for loops of the following kind:

for (const auto cell : cell_data.cell_indices())
{
const auto cell_dofs =
cell_data.get_active_cell_iterator(cell)->as_dof_handler_iterator(
dof_handler);
const auto unit_points = cell_data.get_unit_points(cell);
const auto local_value = cell_data.get_data_view(cell, values);
// user code: not shown
}
std_cxx20::ranges::iota_view< unsigned int, unsigned int > cell_indices() const

Here, we are looping over all cells where points reside and use the index to call the functions get_active_cell_iterator(), get_unit_points(), and get_data_view().

Definition at line 251 of file mpi_remote_point_evaluation.cc.

◆ get_active_cell_iterator()

template<int dim, int spacedim>
Triangulation< dim, spacedim >::active_cell_iterator Utilities::MPI::RemotePointEvaluation< dim, spacedim >::CellData::get_active_cell_iterator ( const unsigned int  cell) const

Return active cell iterator of the processed cell cell.

Definition at line 260 of file mpi_remote_point_evaluation.cc.

◆ get_unit_points()

template<int dim, int spacedim>
ArrayView< const Point< dim > > Utilities::MPI::RemotePointEvaluation< dim, spacedim >::CellData::get_unit_points ( const unsigned int  cell) const

Return unit points of the processed cell cell.

Definition at line 271 of file mpi_remote_point_evaluation.cc.

◆ get_data_view()

template<int dim, int spacedim>
template<typename T >
ArrayView< T > Utilities::MPI::RemotePointEvaluation< dim, spacedim >::CellData::get_data_view ( const unsigned int  cell,
const ArrayView< T > &  values 
) const

Return local view of the processed cell cell for the vector values.
