Constructor & Destructor Documentation

FourthOrderInterpStencil::FourthOrderInterpStencil

(

)

Default constructor.

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

FourthOrderInterpStencil::FourthOrderInterpStencil	(	const IntVect &	a_bdryOffset,
		const int &	a_refineCoarse,
		const int &	a_degree = 3,
		Interval	a_fixedDims = Interval()
	)			[inline]

Full constructor.

Parameters:

a_bdryOffset	in range -(a_degree-1):(a_degree-1), specifies displacement to boundary in each dimension
a_refineCoarse	refinement ratio
a_degree	max degree of polynomials
a_fixedDims	dimensions that are fixed, not interpolated

References define().

FourthOrderInterpStencil::~FourthOrderInterpStencil

)

Destructor.

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

Member Function Documentation

void FourthOrderInterpStencil::define	(	const IntVect &	a_bdryOffset,
		const int &	a_refineCoarse,
		const int &	a_degree = 3,
		Interval	a_fixedDims = Interval()
	)

Actual constructor.

Set up object.

Parameters:

a_bdryOffset	in range -(a_degree-1):(a_degree-1), specifies displacement to boundary in each dimension
a_refineCoarse	refinement ratio
a_degree	max degree of polynomials
a_fixedDims	dimensions that are fixed, not interpolated

void FourthOrderInterpStencil::fillFine	(	FArrayBox &	a_fineFab,
		const FArrayBox &	a_coarseFab,
		const IntVect &	a_coarseDataCell,
		const IntVect &	a_coarseToFineOffset = IntVect::Zero
	)			const

Interpolate to all the fine cells within one coarse cell.

Fill the fine cells inside a_coarseDataCell with interpolated data from a_coarseFab.

The fine cells to be filled in are at m_baseFineBox + m_refineVect * a_coarseDataCell + a_coarseToFineOffset. The coarse cells from which we draw data are (a_coarseDataCell + m_coarseBaseIndices[i*D+[0:D-1]]: 0 <= i < m_stencilSize).

Parameters:

a_fineFab	to fill at m_baseFineBox + m_refineVect*a_coarseDataCell + a_coarseToFineOffset
a_coarseFab	coarse data
a_coarseDataCell	coarse cell with fine subcells to fill in
a_coarseToFineOffset	offset from base coarse cell to coarsened fine cells
