Detailed Description

Class to interpolate coarse-level data to a fine level.

NodeMGInterp manages the interpolation of coarse-level data to fine-level data for multigrid. This class should be considered internal to AMRNodeSolver and not a part of the Chombo API.

Constructor & Destructor Documentation

NodeMGInterp::NodeMGInterp ( )

Default constructor. User must subsequently call define().

NodeMGInterp::~NodeMGInterp ( )

Destructor.

NodeMGInterp::NodeMGInterp ( const DisjointBoxLayout a_grids,
int  a_numcomps,
int  a_refRatio,
const Box a_domain 
)

Defining constructor. Calls define() function with identical arguments.

NodeMGInterp::NodeMGInterp ( const DisjointBoxLayout a_grids,
int  a_numcomps,
int  a_refRatio,
const ProblemDomain a_domain 
)

Defining constructor. Calls define() function with identical arguments.

Member Function Documentation

void NodeMGInterp::define ( const DisjointBoxLayout a_grids,
int  a_numcomps,
int  a_refRatio,
const ProblemDomain a_domain 
)

Defines this object. Existing information is overridden.

Parameters
a_gridsCELL-centered grids at the finer level
a_numcompsnumber of components of data
a_refRatiorefinement ratio between the two levels
a_domainCELL-centered physical domain at the finer level
void NodeMGInterp::define ( const DisjointBoxLayout a_grids,
int  a_numcomps,
int  a_refRatio,
const Box a_domain 
)

Defines this object. Existing information is overridden.

Parameters
a_gridsCELL-centered grids at the finer level
a_numcompsnumber of components of data
a_refRatiorefinement ratio between the two levels
a_domainCELL-centered physical domain at the finer level
bool NodeMGInterp::isDefined ( ) const

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

void NodeMGInterp::interpToFine ( LevelData< NodeFArrayBox > &  a_fine,
const LevelData< NodeFArrayBox > &  a_coarse,
bool  a_sameGrids = false 
)

Adds interpolated coarse-level data to fine-level data.

Parameters
a_finedata at the finer level
a_coarsedata at the coarser level
a_sameGridswhether the finer-level grids are refinements of the coarser-level grids
