We regard + * complex geometries as geometries that can be meshed only with a + * non-negligible number of coarse cells (>10,000): + * - storing the coarse-grid information on every process is too expensive + * from a memory point of view (as done by + * parallel::distributed::Triangulation). Normally, a process only needs a + * small section of the global triangulation, i.e., a small section of the + * coarse grid such that a partitioning of the coarse grid is indeed + * essential. The cells stored on each process consist of the + * @ref GlossLocallyOwnedCell "locally owned cells" and the + * @ref GlossGhostCell "ghost cells". + * - the distribution of the active cells - on the finest level - among all + * processes by simply partitioning a space-filling curve might not lead + * to an optimal result for triangulations that originate from large + * coarse grids: e.g. partitions that belong to the same process might + * be discontinuous, leading to increased communication (within a + * node and beyond). Graph-based partitioning algorithms might be a sound + * alternative to the space filling curve used by + * parallel::distributed::Triangulation. + * + * To be able to construct a fully partitioned triangulation that + * distributes the coarse grid and gives flexibility regarding partitioning, + * the following ingredients are required: + * - a locally relevant coarse-grid triangulation + * (vertices, cell definition; including a layer of ghost cells) + * - a mapping of the locally relevant coarse-grid triangulation into the + * global coarse-grid triangulation + * - information about which cell should be refined as well as information + * regarding the subdomain_id, the level_subdomain_id, manifold_id, + * and boundary_id of each cell. + * + * The ingredients listed above are bundled in the struct + * parallel::fullydistributed::ConstructionData.

Predefined functions to create ConstructionData + * can be found in the namespace dealii::fullydistributed::Utilities. + * + * Once the ConstructionData `construction_data` has been constructed, the + * triangulation `tria` can be created by calling + * `tria.create_triangulation(construction_data);`. + * + * @note This triangulation supports: 1D/2D/3D, hanging nodes, + * geometric multigrid, and periodicity. + * + * @note You can create a triangulation with hanging nodes and multigrid + * levels with create_triangulation().
