Detailed Description

Fourth-order interpolation in time and space to ghost cells.

Constructor & Destructor Documentation

FourthOrderCFInterp() [1/3]

FourthOrderCFInterp::FourthOrderCFInterp ( )

inline

Default constructor.

Object requires define() to be called before all other functions.

References m_defined.

FourthOrderCFInterp() [2/3]

FourthOrderCFInterp::FourthOrderCFInterp ( const DisjointBoxLayout &  a_thisDisjointBoxLayout, const DisjointBoxLayout &  a_coarserDisjointBoxLayout, const int &  a_numStates, const ProblemDomain &  a_coarseDomain, const int &  a_refineCoarse, const int &  a_interpRadius  )

inline

Full constructor.

Parameters

a_thisDisjointBoxLayout	layout at this level
a_coarserDisjointBoxLayout	layout at coarser level
a_numStates	number of variables
a_coarseDomain	problem domain on the coarser level
a_refineCoarse	refinement ratio between this level and the coarser level
a_interpRadius	number of layers of ghost cells to fill by interpolation

References define().

~FourthOrderCFInterp()

FourthOrderCFInterp::~FourthOrderCFInterp ( )

inline

Destructor.

Destroys all objects created by define(). Passed in data references of define() are left alone.

void FourthOrderCFInterp::homogeneousCoarseFineInterp	(	LevelData< FArrayBox > &	a_fineData,
		int	a_srcComp,
		int	a_dstComp,
		int	a_numComp
	)

fill ghostcells as if all the coarse data were zero (useful for multigrid)

Parameters

a_fineData	interpolated solution on this level
a_srcComp	solution on coarser level
a_dstComp	starting fine data component
a_numComp	number of data components to interpolate

define()

void FourthOrderCFInterp::define	(	const DisjointBoxLayout &	a_thisDisjointBoxLayout,
		const DisjointBoxLayout &	a_coarserDisjointBoxLayout,
		const int &	a_numStates,
		const ProblemDomain &	a_coarseDomain,
		const int &	a_refineCoarse,
		const int &	a_interpRadius
	)

Actual constructor.

Set up object.

Parameters

a_thisDisjointBoxLayout	layout at this level
a_coarserDisjointBoxLayout	layout at coarser level
a_numStates	number of variables
a_coarseDomain	problem domain on the coarser level
