Detailed Description

template<class Scalar = double, class LocalOrdinal = int, class GlobalOrdinal = LocalOrdinal, class Node = KokkosClassic::DefaultNode::DefaultNodeType>
class MueLu::BlockedPFactory< Scalar, LocalOrdinal, GlobalOrdinal, Node >

Factory for building blocked, segregated prolongation operators.

Factory for building blocked, segregated prolongation operators of the form \( P=\diag(P_{11},P_{22},\ldots)\), where \( P_{ii}\) are prolongation operators for the corresponding subblocks \(i\) in the blocked operator \( A \)

Parameters
RCP<FactoryBase>AFact = Teuchos::null: factory for generating blocked operator \( A\).

The blocked operator \( A \) is need for accessing the underlaying blocked maps (MapExtractors). Use the AddFactoryManager function to define block rows in the blocked operator. For each block row you have to define a special factory manager that handles the prolongation and restriction operator for the corresponding blocks. The SubBlockAFactory class provides a factory interface for accessing specific blocks in the blocked operator A

// define SubBlockAFactory objects for accessing the diagonal blocks in the blocked operator A
RCP<SubBlockAFactory> A11Fact = Teuchos::rcp(new SubBlockAFactory(MueLu::NoFactory::getRCP(), 0, 0));
RCP<SubBlockAFactory> A22Fact = Teuchos::rcp(new SubBlockAFactory(MueLu::NoFactory::getRCP(), 1, 1));
// define transfer operators for first block row
RCP<TentativePFactory> P11Fact = rcp(new TentativePFactory());
RCP<TransPFactory> R11Fact = rcp(new TransPFactory(P11Fact));
// define transfer operators for second block row
RCP<TentativePFactory> P22TentFact = rcp(new TentativePFactory());
RCP<PgPFactory> P22Fact = rcp(new PgPFactory(P22TentFact));
RCP<GenericRFactory> R22Fact = rcp(new GenericRFactory(P22Fact));
// setup facatory managers for first and second block row
RCP<FactoryManager> M11 = rcp(new FactoryManager());
M11->SetFactory("A", A11Fact);
M11->SetFactory("P", P11Fact);
M11->SetFactory("R", R11Fact);
RCP<FactoryManager> M22 = rcp(new FactoryManager());
M22->SetFactory("A", A22Fact);
M22->SetFactory("P", P22Fact);
M22->SetFactory("R", R22Fact);
// setup blocked transfer operator
// use Teuchos::null as AFactory -> standard "A" variable (in this case the blocked operator A)
RCP<BlockedPFactory> PFact = rcp(new BlockedPFactory());
PFact->SetFactory("A",Teuchos::null); // not necessary (use blocked operator A)
PFact->AddFactoryManager(M11); // add factory manager for first block row
PFact->AddFactoryManager(M22); // add factory manager for second block row
// define restriction operator
// Note: always use GenericRFactory here.
// The simple TransPFactory class cannot handle blocked operators, yet.
RCP<GenericRFactory> RFact = rcp(new GenericRFactory(PFact));
// RAP factory
RCP<RAPFactory> AcFact = rcp(new RAPFactory(PFact, RFact));
