Data structure returned by GridTools::internal::distributed_compute_intersection_locations(). It can be converted to GridTools::internal::DistributedComputePointLocationsInternal, which can be used to reinit Utilities::MPI::RemotePointEvaluation.

Distribute quadrature points according to QGaussSimplex<structdim>(n_points_1D) on found intersections and construct GridTools::internal::DistributedComputePointLocationsInternal from class members. This can be done without searching for points again since all information is locally known.
mapped_quadratures_recv_comp
is a pointer to an empty vector of mapped quadratures. By default it is a nullptr
and the parameter is ignored. Otherwise, the vector is filled with the mapped quadrature rules (in real coordinates) corresponding to recv_components.
The parameter consistent_numbering_of_sender_and_receiver
can be used to ensure points on sender and receiver side are numbered consistently. This parameter is optional if DistributedComputePointLocationsInternal is used to set up RemotePointEvaluation, but might be helpful for debugging or other usage of DistributedComputePointLocationsInternal. Note that setting this parameter true requires an additional communication step during the setup phase.

Helper function for convert_to_distributed_compute_point_locations_internal(). It sends the indices associated to quadrature points at the receiver side to the sender side, where the information is needed to build GridTools::internal::DistributedComputePointLocationsInternal::send_components

Information of each intersection on sending/evaluation side. The elements of the tuple are as follows: 0) cell level and index, 1) rank of the owning process, 2) local index of the owning process, 3) found intersection.
