Function Documentation

duplicate() [1/2]

template<typename T , template< typename > class Cpy>

T amrex::MFUtil::duplicate	(	const BoxArray &	ba,
		const DistributionMapping &	dm,
		const T &	mf_in
	)

Duplicate class T (which must be either of type MultiFab or iMultiFab) using a new BoxArray and DistributionMapping. Data from the source (mf_in) is copied using a ParallelCopy (ghost cells are treated based on the Cpy class (which is either SymmetricGhost or AsymmetricGhost)).

duplicate() [2/2]

template<typename T , template< typename > class Cpy>

T amrex::MFUtil::duplicate	(	const BoxArray &	ba,
		const DistributionMapping &	dm,
		const T &	mf_in,
		const Periodicity &	periodicity
	)

Duplicate class T (which must be either of type MultiFab or iMultiFab) using a new BoxArray and DistributionMapping. Data from the source (mf_in) is copied using a ParallelCopy (ghost cells are treated based on the Cpy class (which is either SymmetricGhost or AsymmetricGhost)). Following the copy operation, a FillBoundary operation is called.

regrid() [1/3]

template<typename T >

T amrex::MFUtil::regrid	(	const BoxArray &	ba,
		const DistributionMapping &	dm,
		const T &	mf_in,
		bool	regrid_ghost = false
	)

Regrid (by duplication) class T (which must be either of type MultiFab or iMultiFab) using the new BoxArray and DistributionMapping. The boolean flag regrid_ghost switched between the SymmetricGhost and AsymmetricGhost copy functions.

regrid() [2/3]

template<typename T >

void amrex::MFUtil::regrid	(	T &	mf_out,
		const BoxArray &	ba,
		const DistributionMapping &	dm,
		const FabFactory< FArrayBox > &	eb_factory,
		const T &	mf_in,
		bool	regrid_ghost = false
	)

Regrid (by duplication) class T. The T-object at the end of the reference mf_out is re-defined using the EBFArrayBoxFactory provided by eb_factory. The boolean flag regrid_ghost switched between the SymmetricGhost and AsymmetricGhost copy functions.

regrid() [3/3]

template<typename T >

void amrex::MFUtil::regrid	(	T &	mf_out,
		const BoxArray &	ba,
		const DistributionMapping &	dm,
		const T &	mf_in,
		bool	regrid_ghost = false
	)

Regrid (by duplication) class T (which must be either of type MultiFab or iMultiFab) using the new BoxArray and DistributionMapping. The T-object at the end of the pointer mf_out is re-defined. The boolean flag regrid_ghost switched between the SymmetricGhost and AsymmetricGhost copy functions.
