Constructor & Destructor Documentation

template<class ScalarType , class MV , class OP >

Belos::FixedPointSolMgr< ScalarType, MV, OP >::FixedPointSolMgr ( )

Empty constructor for FixedPointSolMgr. This constructor takes no arguments and sets the default values for the solver. The linear problem must be passed in using setProblem() before solve() is called on this object. The solver values can be changed using setParameters().

Definition at line 328 of file BelosFixedPointSolMgr.hpp.

template<class ScalarType , class MV , class OP >

Belos::FixedPointSolMgr< ScalarType, MV, OP >::FixedPointSolMgr	(	const Teuchos::RCP< LinearProblem< ScalarType, MV, OP > > &	problem,
		const Teuchos::RCP< Teuchos::ParameterList > &	pl
	)

Basic constructor for FixedPointSolMgr.

This constructor accepts the LinearProblem to be solved in addition to a parameter list of options for the solver manager. These options include the following:

"Block Size" - an int specifying the block size to be used by the underlying block conjugate-gradient solver. Default: 1
"Verbosity" - a sum of MsgType specifying the verbosity. Default: Belos::Errors
"Output Style" - a OutputType specifying the style of output. Default: Belos::General
"Output Stream" - a reference-counted pointer to the output stream where all solver output is sent. Default: Teuchos::rcp(&std::cout,false)
"Output Frequency" - an int specifying how often convergence information should be outputted. Default: -1 (never)
"Show Maximum Residual Norm Only" - a bool specifying whether that only the maximum relative residual norm is printed if convergence information is printed. Default: false
"Timer Label" - a std::string to use as a prefix for the timer labels. Default: "Belos"

ReturnType Belos::FixedPointSolMgr< ScalarType, MV, OP >::solve ( )

overridevirtual

This method performs possibly repeated calls to the underlying linear solver's iterate() routine until the problem has been solved (as decided by the solver manager) or the solver manager decides to quit.

This method calls FixedPointIter::iterate() or CGIter::iterate(), which will return either because a specially constructed status test evaluates to Passed or an std::exception is thrown.

A return from FixedPointIter::iterate() signifies one of the following scenarios:

the maximum number of iterations has been exceeded. In this scenario, the current solutions to the linear system will be placed in the linear problem and return Unconverged.
global convergence has been met. In this case, the current solutions to the linear system will be placed in the linear problem and the solver manager will return Converged

Returns

ReturnType specifying:

Converged: the linear problem was solved to the specification required by the solver manager.
Unconverged: the linear problem was not solved to the specification desired by the solver manager.
