Member Function Documentation

prolongate_and_add()

template<int dim, typename VectorType >

void MGTwoLevelTransfer< dim, VectorType >::prolongate_and_add	(	VectorType &	dst,
		const VectorType &	src
	)		const

Perform prolongation.

restrict_and_add()

template<int dim, typename VectorType >

void MGTwoLevelTransfer< dim, VectorType >::restrict_and_add	(	VectorType &	dst,
		const VectorType &	src
	)		const

Perform restriction.

interpolate()

template<int dim, typename VectorType >

void MGTwoLevelTransfer< dim, VectorType >::interpolate	(	VectorType &	dst,
		const VectorType &	src
	)		const

Perform interpolation of a solution vector from the fine level to the coarse level. This function is different from restriction, where a weighted residual is transferred to a coarser level (transposition of prolongation matrix).

enable_inplace_operations_if_possible()

template<int dim, typename VectorType >

void MGTwoLevelTransfer< dim, VectorType >::enable_inplace_operations_if_possible	(	const std::shared_ptr< const Utilities::MPI::Partitioner > &	partitioner_coarse,
		const std::shared_ptr< const Utilities::MPI::Partitioner > &	partitioner_fine
	)

Enable inplace vector operations if external and internal vectors are compatible.

memory_consumption()

template<int dim, typename VectorType >

std::size_t MGTwoLevelTransfer< dim, VectorType >::memory_consumption

(

)

const

Return the memory consumption of the allocated memory in this class.
