Prolongator factory performing semi-coarsening.
The semi-coarsening is performed along user-provided "vertical lines" (in z-direction). The line detection algorithm can be found in the LineDetectionFactory. Usually, the SemiCoarsenPFactory is used together with the TogglePFactory and a second TentativePFactory which allows to dynamically switch from semi-coarsening to aggregation-based coarsening (or any other compatible coarsening algorithm).
Parameter | type | default | master.xml | validated | requested | description |
---|---|---|---|---|---|---|
A | Factory | null | * | * | Generating factory of the matrix A used during the prolongator smoothing process | |
Nullspace | Factory | null | * | * | Generating factory of the nullspace. The SemiCoarsenPFactory provides a coarse version of the given Nullspace. | |
Coordinates | Factory | NoFactory | * | * | Generating factory for coorindates. The coordinates are expected to be provided on the finest level using the NoFactory mechanism. The coordinates are used to determine the number of z-layers if not otherwise provided by the user. | |
LineDetection_VertLineIds | Factory | null | * | * | Generating factory for LineDetection information. Usually provided by the LineDetectionFactory. Array with vertical line ids for all nodes on current processor. | |
LineDetection_Layers | Factory | null | * | * | Generating factory for LineDetection information. Usually provided by the LineDetectionFactory. Array with layer id for all nodes on current processor. | |
CoarseNumZLayers | Factory | null | * | * | Generating factory for LineDetection information. Usually provided by the LineDetectionFactory. Number of remaining z-layers after semi-coarsening. |
| semicoarsen: coarsen rate | int | * | * | | Coarsening rate along vertical lines (2 corresponds to classical semicoarsening. Values > 2 for more aggressive coarsening). |
The * in the master.xml
column denotes that the parameter is defined in the master.xml
file.
The * in the validated
column means that the parameter is declared in the list of valid input parameters (see SemiCoarsenPFactory::GetValidParameters).
The * in the requested
column states that the data is requested as input with all dependencies (see SemiCoarsenPFactory::DeclareInput).
After SemiCoarsenPFactory::Build the following data is available (if requested)
Parameter | generated by | description |
---|---|---|
P | SemiCoarsenPFactory | Prolongator |
Nullspace | SemiCoarsenPFactory | Coarse nullspace (the fine level nullspace information is coarsened using P to generate a coarse version of the nullspace. No scaling is applied. |
NumZLayers | NoFactory | Number of z layers after coarsening. Necessary input for LineDetectionFactory. Useful input for TogglePFactory. |
