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 (    )

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::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.
