Detailed Description

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

Constructor & Destructor Documentation

FourthOrderFillPatch::FourthOrderFillPatch ( )

Default constructor.

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

FourthOrderFillPatch::FourthOrderFillPatch ( const DisjointBoxLayout a_thisDisjointBoxLayout,
const DisjointBoxLayout a_coarserDisjointBoxLayout,
const int &  a_numStates,
const ProblemDomain a_coarseDomain,
const int &  a_refineCoarse,
const int &  a_interpRadius,
bool  a_fixedTime = false 
)
inline

Full constructor.

Parameters
a_thisDisjointBoxLayoutlayout at this level
a_coarserDisjointBoxLayoutlayout at coarser level
a_numStatesnumber of variables
a_coarseDomainproblem domain on the coarser level
a_refineCoarserefinement ratio between this level and the coarser level
a_interpRadiusnumber of layers of ghost cells to fill by interpolation
a_fixedTimewhether this object is for a fixed time

References define().

FourthOrderFillPatch::~FourthOrderFillPatch ( )

Destructor.

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

void FourthOrderFillPatch::fillInterp ( LevelData< FArrayBox > &  a_fineData,
Real  a_timeInterpCoeff,
int  a_srcComp,
int  a_dstComp,
int  a_numComp 
)

Interpolate in time and space.

Interpolate in time and space to ghost cells of a_fine from coarse data. The time interpolator must already contain the full Taylor polynomial calculated from data at the coarser level.

Parameters
a_fineDatainterpolated solution on this level
a_timeInterpCoefftime interpolation coefficient, in [0:1]
a_srcCompstarting coarse data component
a_dstCompstarting fine data component
a_numCompnumber of data components to interpolate
void FourthOrderFillPatch::fillRK4Intermediate ( LevelData< FArrayBox > &  a_fineData,
Real  a_timeInterpCoeff,
int  a_stage,
int  a_srcComp,
int  a_dstComp,
int  a_numComp 
)

Fill RK4 intermediate in time and space.

Set RK4 intermediate interpolating in time and space to ghost cells of a_fine from coarse data. The time interpolator must already contain the full Taylor polynomial calculated from data at the coarser level.

Parameters
a_fineDatainterpolated solution on this level
a_timeInterpCoefftime interpolation coefficient, in [0:1]
a_stageRK4 stage, in 0:3
a_srcCompstarting coarse data component
a_dstCompstarting fine data component
a_numCompnumber of data components to interpolate
void FourthOrderFillPatch::fillInterp ( LevelData< FArrayBox > &  a_fineData,
const LevelData< FArrayBox > &  a_coarseData,
int  a_srcComp,
int  a_dstComp,
int  a_numComp 
)

Interpolate in space only.

At a fixed time, interpolate in space to ghost cells of a_fine from a_coarse.

Parameters
a_fineDatainterpolated solution on this level
a_coarseDatasolution on coarser level
a_srcCompstarting coarse data component
a_dstCompstarting fine data component
a_numCompnumber of data components to interpolate
TimeInterpolatorRK4& FourthOrderFillPatch::getTimeInterpolator ( )

Return time interpolator object.

Return m_timeInterpolator.

void FourthOrderFillPatch::fillInterpSpaceFromCoarsened ( LevelData< FArrayBox > &  a_fineData,
int  a_srcComp,
int  a_dstComp,
int  a_numComp 
)
protected

Interpolate in space only, from coarsened fine grids.

At a fixed time, interpolate in space to ghost cells of a_fine from m_coarseFineData.

Parameters
a_fineDatainterpolated solution on this level
a_srcCompstarting coarse data component
a_dstCompstarting fine data component
a_numCompnumber of data components to interpolate
