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.


Constructor & Destructor Documentation

CoarseAverage::CoarseAverage  
 

Default constructor. User must subsequently call define().

CoarseAverage::~CoarseAverage  
 

Destructor.

CoarseAverage::CoarseAverage const DisjointBoxLayout   a_fine_domain,
int    a_numcomps,
int    a_ref_ratio
 

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

{\bf Arguments:}\ a_fine_domain (not modified): the fine level domain.\ a_numcomps (not modified): the number of components.\ a_ref_ratio (not modified): the refinement ratio.\

void CoarseAverage::averageToCoarse LevelData< FArrayBox > &    a_coarse_data,
const LevelData< FArrayBox > &    a_fine_data
 

Replaces a_coarse_data with the average of a_fine_data within the coarsening of the domain of the fine level. 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().

{\bf Arguments:}\ a_coarse_data (modified): coarse data. \ a_fine_data (not modified): fine data. \

{\bf This:}\ Well, it's complicated. As far as the user is concerned, this object is not modified. See the design document if you care for details.

void CoarseAverage::define const DisjointBoxLayout   a_fine_domain,
int    a_numcomps,
int    a_ref_ratio
 

Defines this object. Existing information is overriden.

{\bf Arguments:}\ a_fine_domain (not modified): the fine level domain.\ a_numcomps (not modified): the number of components.\ a_ref_ratio (not modified): the refinement ratio.\

{\bf This:}\ ---This object is modified.---

bool CoarseAverage::isDefined   const
 

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

{\bf This:}\ This object is not modified.
