void RBGen::AnasaziPOD::computeBasis ( )

virtual

Compute a basis for the provided snapshots.

Computes bases for the provided snapshots using Anasazi to solve the eigenproblem defined by $ A^T A $ , where A is the snapshot matrix.

Implements RBGen::Method< Epetra_MultiVector, Epetra_Operator >.

Definition at line 67 of file RBGen_AnasaziPOD.cpp.

void RBGen::AnasaziPOD::updateBasis ( const Teuchos::RCP< Epetra_MultiVector > & update_ss )

inlinevirtual

Append new snapshots to the set, and update the basis.

Note: This method is not supported by AnasaziPOD. Calling it has no effect.

Implements RBGen::Method< Epetra_MultiVector, Epetra_Operator >.

Definition at line 43 of file RBGen_AnasaziPOD.h.

Teuchos::RCP<const Epetra_MultiVector> RBGen::AnasaziPOD::getBasis ( ) const

inlinevirtual

Get the basis computed by the reduced basis method.

Implements RBGen::Method< Epetra_MultiVector, Epetra_Operator >.

Definition at line 50 of file RBGen_AnasaziPOD.h.

std::vector<double> RBGen::AnasaziPOD::getSingularValues ( ) const

inlinevirtual

Returns the singular values computed corresponding to the reduced basis.

Implements RBGen::PODMethod< double >.

Definition at line 52 of file RBGen_AnasaziPOD.h.

double RBGen::AnasaziPOD::getCompTime ( ) const

inlinevirtual

Returns the computational time taken to compute the reduced basis.

Implements RBGen::Method< Epetra_MultiVector, Epetra_Operator >.

Definition at line 54 of file RBGen_AnasaziPOD.h.

void RBGen::AnasaziPOD::Initialize	(	const Teuchos::RCP< Teuchos::ParameterList > &	params,
		const Teuchos::RCP< const Epetra_MultiVector > &	ss,
		const Teuchos::RCP< RBGen::FileIOHandler< Epetra_Operator > > &	fileio = `Teuchos::null`
	)

virtual

Initialize the method with the given parameter list and snapshot set.

Implements RBGen::Method< Epetra_MultiVector, Epetra_Operator >.

Definition at line 29 of file RBGen_AnasaziPOD.cpp.

void RBGen::AnasaziPOD::Reset ( const Teuchos::RCP< Epetra_MultiVector > & new_ss )

inlinevirtual

Reset the snapshot set used to compute the reduced basis.

Implements RBGen::Method< Epetra_MultiVector, Epetra_Operator >.

Definition at line 66 of file RBGen_AnasaziPOD.h.

void RBGen::AnasaziPOD::ResetOp ( const Teuchos::RCP< Epetra_Operator > & new_op )

inline
