Detailed Description

template<class VectorType, class SolverType, class MatrixType, class PreconditionerType>
class MGCoarseGridIterativeSolver< VectorType, SolverType, MatrixType, PreconditionerType >

Coarse grid multigrid operator for an iterative solver.

This class provides a wrapper for a deal.II iterative solver with a given matrix and preconditioner as a coarse grid operator.

Constructor & Destructor Documentation

◆ MGCoarseGridIterativeSolver() [1/2]

template<class VectorType , class SolverType , class MatrixType , class PreconditionerType >
MGCoarseGridIterativeSolver< VectorType, SolverType, MatrixType, PreconditionerType >::MGCoarseGridIterativeSolver ( )

Default constructor.

◆ MGCoarseGridIterativeSolver() [2/2]

template<class VectorType , class SolverType , class MatrixType , class PreconditionerType >
MGCoarseGridIterativeSolver< VectorType, SolverType, MatrixType, PreconditionerType >::MGCoarseGridIterativeSolver ( SolverType solver,
const MatrixType &  matrix,
const PreconditionerType &  precondition 
)

Constructor. Only a reference to these objects is stored, so their lifetime needs to exceed the usage in this class.

Member Function Documentation

◆ initialize()

template<class VectorType , class SolverType , class MatrixType , class PreconditionerType >
void MGCoarseGridIterativeSolver< VectorType, SolverType, MatrixType, PreconditionerType >::initialize ( SolverType solver,
const MatrixType &  matrix,
const PreconditionerType &  precondition 
)

Initialize with new data, see the corresponding constructor for more details.

◆ clear()

template<class VectorType , class SolverType , class MatrixType , class PreconditionerType >
void MGCoarseGridIterativeSolver< VectorType, SolverType, MatrixType, PreconditionerType >::clear ( )

Clear all pointers.

◆ operator()()

template<class VectorType , class SolverType , class MatrixType , class PreconditionerType >
virtual void MGCoarseGridIterativeSolver< VectorType, SolverType, MatrixType, PreconditionerType >::operator() ( const unsigned int  level,
VectorType &  dst,
const VectorType &  src 
) const
overridevirtual

Implementation of the abstract function. Calls the solve method of the given solver with matrix, vectors, and preconditioner.

Implements MGCoarseGridBase< VectorType >.
