Detailed Description

LevelFluxRegister-A class to encapsulate a levels worth of flux registers.

A LevelFluxRegister handles all the data choreography necessary to create a levels worth of flux registers. You send a pointer to a valid LevelCFStencil to its constructor or define function and it parsels out all the necessary information to the grid flux registers which hands it to the flux registers. The actual functions to manipulate data in the flux registers live in the class FluxRegister.


Constructor & Destructor Documentation

LevelFluxRegister::LevelFluxRegister  
 

Default constructor. Creates an uninitialized levelfluxregister.

LevelFluxRegister::LevelFluxRegister const DisjointBoxLayout   a_dbl,
const DisjointBoxLayout   a_dblCoarse,
const Box   a_dProblem,
int    a_nRefine,
int    a_nComp
 

Full constructor. Calls the define function which creates a levels worth of flux registers. a_dProblem is fine-level domain

LevelFluxRegister::LevelFluxRegister const DisjointBoxLayout   a_dbl,
const DisjointBoxLayout   a_dblCoarse,
const ProblemDomain   a_dProblem,
int    a_nRefine,
int    a_nComp
 

Full constructor. Calls the define function which creates a levels worth of flux registers. a_dProblem is fine-level domain

LevelFluxRegister::~LevelFluxRegister  
 

LevelFluxRegister::LevelFluxRegister const LevelFluxRegister &    [private]
 

there is no copy constructor for this class


Member Function Documentation

void LevelFluxRegister::define const DisjointBoxLayout   a_dbl,
const DisjointBoxLayout   a_dblCoarse,
const ProblemDomain   a_dProblem,
int    a_nRefine,
int    a_nComp
 

Full define function. Creates a levels worth of flux registers. The values in the flux registers are still undefined, however. To zero the fluxregisters, you must call setToZero().

void LevelFluxRegister::define const DisjointBoxLayout   a_dbl,
const DisjointBoxLayout   a_dblCoarse,
const Box   a_dProblem,
int    a_nRefine,
int    a_nComp
 

Full define function. Creates a levels worth of flux registers. The values in the flux registers are still undefined, however. To zero the fluxregisters, you must call setToZero().

void LevelFluxRegister::dump  
 

void LevelFluxRegister::dumpHiCoar int    idir
 

void LevelFluxRegister::dumpHiFine int    idir
 

void LevelFluxRegister::dumpLoCoar int    idir
 

void LevelFluxRegister::dumpLoFine int    idir
 

void LevelFluxRegister::incrementCoarse FArrayBox   a_coarseFlux,
Real    a_scale,
const DataIndex   a_coarseDataIndex,
const Interval   a_srcInterval,
const Interval   a_dstInterval,
int    a_dir
 

increments the register with data from coarseFlux, multiplied by scale. coarseFlux must contain the coarse fluxes in the dir direction for the grid m_coarseLayout[coarseDataIndex]. By convention, only the low side flux is used to avoid double-counting at coarse-fine interfaces. This operation is local.

void LevelFluxRegister::incrementFine FArrayBox   a_fineFlux,
Real    a_scale,
const DataIndex   a_fineDataIndex,
const Interval   a_srcInterval,
const Interval   a_dstInterval,
int    a_dir,
Side::LoHiSide    a_sd
 

increments the register with data from fineFlux, multiplied by scale. fineFlux must contain the coarse fluxes in the dir direction for the grid m_fineLayout[fineDataIndex]. This operation is local.

int LevelFluxRegister::index int    dir,
Side::LoHiSide    side
[static, protected]
 

bool LevelFluxRegister::isDefined   const
 

has full define function been called? return true if so.

void LevelFluxRegister::operator= const LevelFluxRegister &    [private]
 

there is no operator= for this class

void LevelFluxRegister::reflux LevelData< FArrayBox > &    a_uCoarse,
const Interval   a_coarse_interval,
const Interval   a_flux_interval,
Real    a_scale
 

increments uCoarse with the reflux divergence of the contents of the flux register. This operation is global and blocking.

void LevelFluxRegister::reflux LevelData< FArrayBox > &    a_uCoarse,
Real    a_scale
 

increments uCoarse with the reflux divergence of the contents of the flux register. Note that there is no srccomp etc crap here. this is done for all components so uCoarse has to have the same number of components as input nComp. This operation is global and blocking.

void LevelFluxRegister::setDefaultValues   [protected]
 

void LevelFluxRegister::setToZero  
 

Initialize values of registers to zero.

void LevelFluxRegister::undefine  
 

Modifies this LevelFluxRegister so that it is returned to the uninitialized state. User must now call the full define() before using it.
