Detailed Description

Replaces coarse-level data with an average of fine-level data.

This class replaces data at a coarse level of refinement with an average of data at a finer level of refinement, in areas where fine data is present. Coarse-level data is not modified where fine-level data is not present.

Member Function Documentation

void NodeCoarseAverage::define	(	const DisjointBoxLayout &	a_gridsFine,
		const DisjointBoxLayout &	a_gridsCoarse,
		int	a_numcomps,
		int	a_refRatio,
		const ProblemDomain &	a_domainFine
	)

Defines this object. Existing information is overriden.

Parameters:

a_gridsFine	CELL-centered grids at the fine level
a_gridsCoarse	CELL-centered grids at the coarse level
a_numcomps	number of components of data
a_refRatio	refinement ratio between the two levels
a_domainFine	CELL-centered physical domain at the fine level

void NodeCoarseAverage::define	(	const DisjointBoxLayout &	a_gridsFine,
		const DisjointBoxLayout &	a_gridsCoarse,
		int	a_numcomps,
		int	a_refRatio,
		const Box &	a_domainFine
	)

Defines this object. Existing information is overriden.

Parameters:

a_gridsFine	CELL-centered grids at the fine level
a_gridsCoarse	CELL-centered grids at the coarse level
a_numcomps	number of components of data
a_refRatio	refinement ratio between the two levels
a_domainFine	CELL-centered physical domain at the fine level

void NodeCoarseAverage::define	(	const DisjointBoxLayout &	a_gridsCoarse,
		int	a_numcomps,
		int	a_refRatio,
		const ProblemDomain &	a_domainFine
	)

Defines this object. Existing information is overriden. Fine grids are refinements of coarse grids.

Parameters:

a_gridsCoarse	CELL-centered grids at the coarse level
a_numcomps	number of components of data
a_refRatio	refinement ratio between the two levels
a_domainFine	CELL-centered physical domain at the fine level

void NodeCoarseAverage::define	(	const DisjointBoxLayout &	a_gridsCoarse,
		int	a_numcomps,
		int	a_refRatio,
		const Box &	a_domainFine
	)

Defines this object. Existing information is overriden. Fine grids are refinements of coarse grids.

Parameters:

a_gridsCoarse	CELL-centered grids at the coarse level
a_numcomps	number of components of data
a_refRatio	refinement ratio between the two levels
a_domainFine	CELL-centered physical domain at the fine level

bool NodeCoarseAverage::isDefined

(

)

const

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

void NodeCoarseAverage::setVerbose

(

bool

a_verbose

)

Set whether the solver gives output while solving. Default is true.

void NodeCoarseAverage::averageToCoarse	(	LevelData< NodeFArrayBox > &	a_coarse,
		LevelData< NodeFArrayBox > &	a_fine
	)

Replaces coarse data with the average of nearby cells' fine data on the interior nodes of the coarsened fine-level domain. Elsewhere, the coarse data is unchanged.

It is an error to call if not this->isDefined().

The domain of a_fine should be the same as a_gridsFine specified in the most recent call to define().

It is expected that the coarse and fine levels' domains are properly nested. Both a_coarse and a_fine should have the same number of components specified in the most recent call to define().

The fine data is modified only in exchange(). A work array is also modified.

Parameters:

a_coarse	coarse data
a_fine	fine data, modified in exchange()
