Member Function Documentation

prolongate()

template<int dim, typename VectorType >

void MGTwoLevelTransfer< dim, VectorType >::prolongate	(	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).
