Detailed Description

replaces coarse level data with a coarsening of fine level data.

This class replaces data at a coarse level of refinement with a coarsening 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.

Constructor & Destructor Documentation

EBCoarsen() [1/3]

EBCoarsen::EBCoarsen

(

)

Default constructor. User must subsequently call define().

~EBCoarsen()

EBCoarsen::~EBCoarsen

(

)

EBCoarsen() [2/3]

EBCoarsen::EBCoarsen	(	const EBLevelGrid &	eblgFine,
		const EBLevelGrid &	eblgCoar,
		const int &	nref,
		const int &	nvar
	)

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

{ Arguments:}\ eblgFine, eblgCoar: The fine and coarse layouts of the data.\ nref: The refinement ratio between the two levels. \ nvar: The number of variables contained in the data at each VoF.

Member Function Documentation

define()

void EBCoarsen::define	(	const EBLevelGrid &	eblgFine,
		const EBLevelGrid &	eblgCoar,
		const int &	nref,
		const int &	nvar
	)

Defines this object. Existing information is overriden.

{ Arguments:}\ eblgFine, eblgCoar: The fine and coarse layouts of the data.\ nref: The refinement ratio between the two levels. \ nvar: The number of variables contained in the data at each VoF.

isDefined()

bool EBCoarsen::isDefined

(

)

const

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

coarsenFine()

void EBCoarsen::coarsenFine	(	LevelData< EBCellFAB > &	a_coarData,
		const LevelData< EBCellFAB > &	a_fineData,
		const Interval &	a_variables
	)

Replaces a_coarse_data with the coarsening of a_fine_data within the coarsening of the domain of the fine level. This is different from averaging in that we are trying to approximate the coarse value at the cell center. (averaging approximates the average over the cell) Elsewhere, the coarse data is unchanged. 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(). a_fine_data needs pre-filled ghost cells of size 1 ONLY IF refRat<4

{ Arguments:}\ coarData: The data over the coarse layout.\ fineData: The data over the fine layout. \ Fine and coarse data must have the same number of variables.\ variables: The variables to coarsen. Those not in this range will be left alone. This range of variables must be in both the coarse and fine data.
