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_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
