| @class MatrixFreeTentativePFactory class. | ||
| @brief Factory for building the matrix-free tentative restrictor. | ||
| Factory for creating the matrix-free tentative restrictor. Nullspace vectors are split across aggregates so that they | ||
| have local support. The vectors with local support are factored via LAPACK QR. The Q becomes the | ||
| tentative prolongator, and the R becomes the coarse nullspace. | ||
| Note that the MatrixFreeTentativePFactory also creates the coarse null space vectors, that is, it serves as generating | ||
| factory for the Nullspace vectors on the coarse levels. To feed in the near null space vectors on the finest | ||
| level one has to use the NullspaceFactory. | ||
| @ingroup MueLuTransferClasses | ||
| ## Input/output of MatrixFreeTentativePFactory ## | ||
| ### User parameters of MatrixFreeTentativePFactory ### | ||
| Parameter | type | default | master.xml | validated | requested | description | ||
| ----------|------|---------|:----------:|:---------:|:---------:|------------ | ||
| Aggregates | Factory | null | | * | * | Generating factory of the aggregates (of type "Aggregates" produced, e.g., by the UncoupledAggregationFactory) | ||
| Nullspace | Factory | null | | * | * | Generating factory of the fine nullspace vectors (of type "MultiVector"). In the default case the same instance of the MatrixFreeTentativePFactory is also the generating factory for the null space vectors (on the next coarser levels). Therefore, it is recommended to declare the MatrixFreeTentativePFactory to be the generating factory of the "Nullspace" variable globally using the FactoryManager object! For defining the near null space vectors on the finest level one should use the NullspaceFactory. | ||
| UnAmalgamationInfo | Factory | null | | * | * | Generating factory of UnAmalgamationInfo. This data (of type "AmalgamationInfo") is produced by the AmalgamationFactory class. The default option should be fine for most standard cases though. | ||
| CoarseMap | Factory | null | | * | * | Generating factory of the coarse map. The map generates the coarse domain map of the prolongation operator. The default choice should be fine as long as you do not wish some offset in the domain map (e.g. for block operators in multiphysics problems). The data is generated by the CoarseMapFactory. | ||
| The * in the @c master.xml column denotes that the parameter is defined in the @c master.xml file.<br> | ||
| The * in the @c validated column means that the parameter is declared in the list of valid input parameters (see MatrixFreeTentativePFactory::GetValidParameters).<br> | ||
| The * in the @c requested column states that the data is requested as input with all dependencies (see MatrixFreeTentativePFactory::DeclareInput). | ||
| ### Variables provided by MatrixFreeTentativePFactory ### | ||
| After MatrixFreeTentativePFactory::Build the following data is available (if requested) | ||
| Parameter | generated by | description | ||
| ----------|--------------|------------ | ||
| | R | MatrixFreeTentativePFactory | Non-smoothed "tentative" prolongation operator (with piece-wise constant transfer operator basis functions) | ||
| | Nullspace | MatrixFreeTentativePFactory | Coarse near null space vectors. Please also check the documentation of the NullspaceFactory for the special dependency tree of the "Nullspace" variable throughout all multigrid levels. | ||
