Detailed Description

Specialization of ug::HangingNodeRefiner for ug::MultiGrid.

This class should be used, if hanging node refinement shall be applied on a hierarchical grid (ug::MultiGrid).

New elements will be constructed one level above their parent elements.

HangingNodeRefiner_MultiGrid supports coarsening. Please note that coarsening presumably has not yet reached its final implementation and behavior may thus change in future revisions. In the current implementation, refinement marks are removed during coarsening and coarsening marks are removed during refinement. In order to use coarsening and refinement on thus should first mark all elements which shall be coarsened, perform coarsening, then mark all elements will shall be refined and perform refinement (or vice versa).

Take a look at ug::HangingNodeRefinerBase for a more in-depth documentation.

Todo:: : Avoid the removal of refinement marks during coarsening and of coarsening marks during refinement.

This callback is called during execution of the refine() method after collect_objects_for_refine has returned. It is responsible to mark elements for hnode refinement. That means all elements on which a hanging node or constrained children shall be created have to be marked using mark_for_hnode_refinement during this method. The default implementation performs this marking for all local elements. Make sure to not mark any new elements for refinement during this method.

void ug::HangingNodeRefiner_MultiGrid::collect_objects_for_coarsen ( bool scheduleCoarseningBeginsMessage = false )

adjusts the selection marks to those specified in HNodeCoarsenMarks.

This method does not alter the selection itself, it only alters the selection-mark, associated with each selected element. It neither selects nor deselects any elements. It iterates over all selected elements of the given type and assigns one of the marks, depending on how many associated elements of the next higher dimension are selected. Note that this method should only be called for vertices, edges and faces. It does not make sense to call it for volumes. Applies marks like RM_COARSEN_CONSTRAINING or RM_COARSEN_UNCONSTRAIN This method should first be called for Face, then for Edge, then for Vertex. deselect coarsen families, which are adjacent to unselected constraining elements If at least one family was deselected, this method returns true. called by the coarsen method in order to adjust the selection to valid elements. This method is responsible to mark all elements that shall be coarsened. Only sub-surface elements may be coarsened. If a sub-surface element has a side, which is not a sub-surface element, then the element may not be coarsened. If scheduleCoarseningBeginsMessage is set to true, the method will schedule a GridMessage_Adaption message which indicates that coarsening begins.

◆ contains_edges()

virtual bool ug::HangingNodeRefiner_MultiGrid::contains_edges ( )

called to check, whether another iteration of collect_objects_for_coarsen has to be performed.

This method is especially useful if coarsening shall be applied in a parallel environment. Each process calls this method and basses a boolean, which indicates if it requires the continuation of collect_objects_for_coarsen. If one process does require continuation, then all processes have to continue. The default implementation simply returns the local status. called during collect_objects_for_coarsen when coarsen-marks shall be distributed This method is especially useful if coarsening shall be applied in a parallel environment. A derived class can implement this method to schedule communication.

◆ perform_coarsening()

bool ug::HangingNodeRefiner_MultiGrid::perform_coarsening ( )

protectedvirtual

performs coarsening on the elements marked with RM_COARSEN.

The grid's message hub is informed using a "GridAdaption" message, passing an instance of GridMessage_Adapation, with values GMAT_HNODE_COARSENING_BEGINS and GMAT_HNODE_COARSENING_ENDS. See lib_grid/lib_grid_messages.h for more details.

automatically adjusts the selection so that only valid coarsening operations are executed. Not that refinement marks are removed in this process.

During a coarsening step only elements from the surface layer are removed. If not all children of a sub-surface element are marked, then the marks are ignored.

Note that coarsen in contrary to refine is conservative. While refine extends the selection to construct a valid grid, coarsen shrinks the selection. On could think of implementing an alternative non conservative coarsen approach. However, the conservative one is the one mostly used in adaptive multigrid methods and was thus chosen here.

coarsen returns false, if no elements have been coarsened, true if at least one has been coarsened.
