Detailed Description

replaces face-centered fine data with interpolation of coarse level data.

This class replaces data at a fine level of refinement with data interpolated from a coarser level of refinement. Interpolation on fine faces which overlie coarse faces is piecewise bi(tri)linear, with van Leer slopes if there is room for the stencil, with lower-order slopes if there isn't. For the intermediate fine-level faces, interpolate linearly between the corresponding fine-grid faces which do overlie coarse-grid faces.

Constructor & Destructor Documentation

◆ FineInterpFace() [1/3]

FineInterpFace::FineInterpFace ( )

Default constructor. User must subsequently call define().

◆ ~FineInterpFace()

FineInterpFace::~FineInterpFace ( )

Destructor.

◆ FineInterpFace() [2/3]

FineInterpFace::FineInterpFace ( const DisjointBoxLayout a_fine_domain,
const int &  a_numcomps,
const int &  a_ref_ratio,
const Box a_fine_problem_domain 
)

Defining constructor. Constructs a valid object. Equivalent to default construction followed by define().

{ Arguments:}\ a_fine_domain (not modified): the fine level domain.\ a_numcomps (not modified): the number of components.\ a_ref_ratio (not modified): the refinement ratio.\ a_fine_problem_domain (not modified): problem domain at the fine level.\

◆ FineInterpFace() [3/3]

FineInterpFace::FineInterpFace ( const DisjointBoxLayout a_fine_domain,
const int &  a_numcomps,
const int &  a_ref_ratio,
const ProblemDomain a_fine_problem_domain 
)

Defining constructor. Constructs a valid object. Equivalent to default construction followed by define().

{ Arguments:}\ a_fine_domain (not modified): the fine level domain.\ a_numcomps (not modified): the number of components.\ a_ref_ratio (not modified): the refinement ratio.\ a_fine_problem_domain (not modified): problem domain at the fine level.\

Member Function Documentation

◆ define() [1/2]

void FineInterpFace::define ( const DisjointBoxLayout a_fine_domain,
const int &  a_numcomps,
const int &  a_ref_ratio,
const Box a_fine_problem_domain 
)

Defines this object. Existing information is overriden.

{ Arguments:}\ a_fine_domain (not modified): the fine level domain.\ a_numcomps (not modified): the number of components.\ a_ref_ratio (not modified): the refinement ratio.\ a_fine_problem_domain (not modified): problem domain at the fine level.\

{ This:}\ —This object is modified.—

◆ define() [2/2]

void FineInterpFace::define ( const DisjointBoxLayout a_fine_domain,
const int &  a_numcomps,
const int &  a_ref_ratio,
const ProblemDomain a_fine_problem_domain 
)

Defines this object. Existing information is overriden.

{ Arguments:}\ a_fine_domain (not modified): the fine level domain.\ a_numcomps (not modified): the number of components.\ a_ref_ratio (not modified): the refinement ratio.\ a_fine_problem_domain (not modified): problem domain at the fine level.\

{ This:}\ —This object is modified.—

◆ isDefined()

bool FineInterpFace::isDefined ( ) const

Returns true if this object was created with the defining constructor or if define() has been called.

{ This:}\ This object is not modified.

◆ interpToFine()

void FineInterpFace::interpToFine ( LevelData< FluxBox > &  a_fine_data,
const LevelData< FluxBox > &  a_coarse_data,
bool  a_averageFromDest = false 
)

Replaces a_fine_data with data interpolated from a_coarse_data. It is an error to call if not this->isDefined(). The domain of a_fine_data should be the same as the fine domain specified in the most recent call to define(). It is expected that the coarse and fine level's domains are properly nested. Both a_coarse_data and a_fine_data should have the same number of components specified in the most recent call to define().

{ Arguments:}\ a_fine_data (modified): fine data. \ a_coarse_data (not modified): coarse data. \

{ This:}\ Well, it's complicated. As far as the user is concerned, this object is not modified. See the design document if you care for details.

◆ interpGridData()

void FineInterpFace::interpGridData ( BaseFab< Real > &  a_fine,
const BaseFab< Real > &  a_coarse,
const Box a_coarsened_fine_box,
const int &  a_ref_ratio,
const int &  a_dir 
) const
