getPreconditionerFromFactory()

template<class Operator>

std::shared_ptr< Preconditioner< typename Operator::domain_type, typename Operator::range_type > > Dune::getPreconditionerFromFactory	(	std::shared_ptr< Operator >	op,
		const ParameterTree &	config )

Construct a Preconditioner for a given Operator.

getSolverFromFactory()

template<class Operator>

std::shared_ptr< InverseOperator< typename Operator::domain_type, typename Operator::range_type > > Dune::getSolverFromFactory	(	std::shared_ptr< Operator >	op,
		const ParameterTree &	config,
		std::shared_ptr< Preconditioner< typename Operator::domain_type, typename Operator::range_type > >	prec = nullptr )

Instantiates an InverseOperator from an Operator and a configuration given as a ParameterTree.

Parameters

op	Operator
config	ParameterTree with configuration
prec	Preconditioner

Example ini File that can be passed in to construct a CGSolver with a SSOR preconditioner:

type = cgsolver
verbose = 1
maxit = 1000
reduction = 1e-5

[preconditioner]
type = ssor
iterations = 1
relaxation = 1

Template Parameters

Operator

type of the operator, necessary to deduce the matrix type etc.
