See the documentation of + * this particular function for details on the algorithm and all featured + * formulas. + * + * In theory, the combination of hp::Refinement::predict_error() to predict + * how the error will change with parallel::distributed::CellDataTransfer + * to transfer data across meshes forms the intended way to apply the + * prediction algorithm. However, p4est determines the details of grid + * refinement in the parallel distributed case; consequently, it yields more + * reliable and trustworthy results when we determine the predicted errors + * during the adaptation process. This is achieved with this class, similar + * to the parallel::distributed::SolutionTransfer and + * parallel::distributed::CellDataTransfer classes. + * + * Before adaptation happens, one or multiple vectors containing error + * estimates for every cell have to be registered with this class using the + * prepare_for_coarsening_and_refinement() functions. Performing adaptation + * on the triangulation initiates the calculation of the error prediction + * based on how p4est performed grid adaptation. After the refinement + * process, the predicted errors need to be unpacked on the updated mesh via + * one of the unpack() functions. + * + * The following code snippet demonstrates how to impose hp-adaptivity based + * on refinement history in a parallel distributed application: + * @code + * // [initialization...] + * Vector predicted_error_per_cell(triangulation.n_active_cells()); + * for(unsigned int i = 0; i < triangulation.n_active_cells(); ++i) + * predicted_error_per_cell[i] = std::numeric_limits::infinity(); + * + * // [during each refinement step...] + * // set h-adaptivity flags + * Vector estimated_error_per_cell(triangulation.n_active_cells()); + * KellyErrorEstimator::estimate(...); + * parallel::distributed::GridRefinement:: + * refine_and_coarsen_fixed_{number|fraction}(...); + * + * // set p-adaptivity flags + * hp::Refinement::p_adaptivity_from_reference( + * hp_dof_handler, + * estimated_error_per_cell, + * predicted_error_per_cell + * std::less(), + * std::less()); + * hp::Refinement::{choose|force}_p_over_h(hp_dof_handler); + * + * // perform adaptation and predict error for the subsequent adaptation + * parallel::distributed::ErrorPredictor predictor(hp_dof_handler); + * predictor.prepare_for_coarsening_and_refinement(estimated_error_per_cell); + * triangulation.execute_coarsening_and_refinement(); + * + * // unpack predicted errors + * predicted_error_per_cell.reinit(triangulation.n_active_cells()); + * predictor.unpack(predicted_error_per_cell); + * @endcode + * + * For serialization of predicted errors, use the + * parallel::distributed::CellDataTransfer class. + * + * @ingroup distributed + * @author Marc Fehling, 2019 - 2020 + */ + template + class ErrorPredictor + { + public: + /** + * Constructor. + * + * @param[in] dof The hp::DoFHandler on which all operations will + * happen.
