Constructor & Destructor Documentation

FourthOrderPatchInterp::FourthOrderPatchInterp

(

)

Default constructor.

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

virtual FourthOrderPatchInterp::~FourthOrderPatchInterp

(

)

[virtual]

Destructor.

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

FourthOrderPatchInterp::FourthOrderPatchInterp

(

const FourthOrderPatchInterp &

a_input

)

[inline, private]

Member Function Documentation

virtual void FourthOrderPatchInterp::define	(	const ProblemDomain &	a_domain,
		const int &	a_refineCoarse,
		const int &	a_maxStencilDist,
		Interval	a_fixedDims = Interval()
	)			[virtual]

Actual constructor.

Set up object.

Parameters:

a_domain	problem domain on this level
a_refineCoarse	refinement ratio between this level and next coarser level
a_maxStencilDist	maximum distance of stencil from domain boundary
a_fixedDims	dimensions that are fixed, not interpolated

virtual void FourthOrderPatchInterp::setCoarseBox

(

const Box &

a_coarseBox

)

[virtual]

Set the coarse box before calling setStencil or interpToFine.

virtual void FourthOrderPatchInterp::setStencil

(

BaseFab< IntVect > &

a_stencil

)

[virtual]

Set stencil for current coarse box and domain.

Set a_stencil for m_coarseBox.

virtual void FourthOrderPatchInterp::interpToFine	(	FArrayBox &	a_fine,
		const FArrayBox &	a_coarse,
		const BaseFab< IntVect > &	a_stencils
	)			[virtual]

Interpolate in space.

Interpolate in space to a_fine from a_coarse.

Parameters:

a_fine	interpolated solution on this level
a_coarse	coarse solution
a_stencils	stencils

virtual void FourthOrderPatchInterp::interpToFine	(	FArrayBox &	a_fine,
		const FArrayBox &	a_coarse,
		const BaseFab< IntVect > &	a_stencils,
		const IntVectSet &	a_ivs
	)			[virtual]

Interpolate in space.

Interpolate in space to a_fine from a_coarse at fine cells within the coarse cells listed in a_ivs.

Parameters:

a_fine	interpolated solution on this level
a_coarse	coarse solution
a_stencils	stencils
a_ivs	we fill in fine cells within these coarse cells

void FourthOrderPatchInterp::operator=
