NodeMGInterp Class Reference

#include <NodeMGInterp.H>

List of all members.


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.

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_grids  CELL-centered grids at the finer level
a_numcomps  number of components of data
a_refRatio  refinement ratio between the two levels
a_domain  CELL-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_grids  CELL-centered grids at the finer level
a_numcomps  number of components of data
a_refRatio  refinement ratio between the two levels
a_domain  CELL-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_fine  data at the finer level
a_coarse  data at the coarser level
a_sameGrids  whether the finer-level grids are refinements of the coarser-level grids
