Member Function Documentation

template<typename time = time_precision>

virtual void pfasst::ITransfer< time >::fas	(	time	dt,
		shared_ptr< ISweeper< time >>	dst,
		shared_ptr< const ISweeper< time >>	src
	)

pure virtual

Compute FAS correction between the coarse and fine sweepers.

Parameters

[in]	dt	width of the time step to compute FAS correction for
[in,out]	dst	sweeper to compute FAS correction for (i.e. coarse level)
[in]	src	sweeper to compute FAS correction from (i.e. fine level)

Implemented in pfasst::examples::boris::InjectiveTransfer< scalar, time >, and pfasst::encap::PolyInterpMixin< time >.

template<typename time = time_precision>

virtual void pfasst::ITransfer< time >::interpolate	(	shared_ptr< ISweeper< time >>	dst,
		shared_ptr< const ISweeper< time >>	src,
		bool	interp_initial = `false`
	)

pure virtual

Interpolate, in time and space, from the coarse sweeper to the fine sweeper.

Parameters

[in,out]	dst	sweeper to interpolate onto (i.e. fine level)
[in]	src	sweeper to interpolate from (i.e. coarse level)
[in]	interp_initial	`true` if a delta for the initial condtion should also be computed (PFASST)

Implemented in pfasst::examples::boris::InjectiveTransfer< scalar, time >, and pfasst::encap::PolyInterpMixin< time >.

template<typename time >

void pfasst::ITransfer< time >::interpolate_initial	(	shared_ptr< ISweeper< time >>	dst,
		shared_ptr< const ISweeper< time >>	src
	)

virtual

Interpolate initial condition from the coarse sweeper to the fine sweeper.

Parameters

[in,out]	dst	sweeper to interpolate onto (i.e. fine level)
[in]	src	sweeper to interpolate from (i.e. coarse level)

Exceptions

NotImplementedYet This function is required by PFASST

virtual void pfasst::ITransfer< time >::restrict	(	shared_ptr< ISweeper< time >>	dst,
		shared_ptr< const ISweeper< time >>	src,
		bool	restrict_initial = `false`
	)

pure virtual

Restrict, in time and space, from the fine sweeper to the coarse sweeper.

Parameters

[in,out]	dst	sweeper to restrict onto (i.e. coarse level)
[in]	src	sweeper to restrict from (i.e. fine level)
[in]	restrict_initial	`true` if the initial condition should also be restricted
