Constructor & Destructor Documentation

EBLevelRedist::EBLevelRedist (  ) 

Default constructor. User must subsequently call define().

EBLevelRedist::~EBLevelRedist (  ) 

EBLevelRedist::EBLevelRedist ( const DisjointBoxLayout a_dbl,
const EBISLayout a_ebisl,
const ProblemDomain a_domain,
const int &  a_ncomp,
int  a_redistRad = 1,
bool  a_do2DStencil = false 
)

Defining constructor. Constructs a valid object. Equivalent to default construction followed by define(). ebisl needs ghost cells out to 3*redistradius of the stencil. This sets the stencil to volume-weighted. Use resetWeights to set to mass weighted or whatever.

EBLevelRedist::EBLevelRedist ( const EBLevelRedist a_stenin  )  [inline, private]

Member Function Documentation

void EBLevelRedist::define ( const DisjointBoxLayout a_dbl,
const EBISLayout a_ebisl,
const ProblemDomain a_domain,
const int &  a_ncomp,
int  a_redistRad = 1,
bool  a_do2DStencil = false 
)

Defines this object. Existing information is overriden. ebisl needs ghost cells out to 3*redistradius

void EBLevelRedist::resetWeights ( const LevelData< EBCellFAB > &  modifier,
const int &  ivar 
)

Modify the weights in the stencil by multiplying by the inputs in a normalized way. If you want mass weighting, send in the density.

void EBLevelRedist::increment ( const BaseIVFAB< Real > &  massDiff,
const DataIndex datInd,
const Interval variables 
)

Store the input mass difference in the buffers of the class by INCREMENTING the buffer. \ dm += massDiff

void EBLevelRedist::redistribute ( LevelData< EBCellFAB > &  solution,
const Interval variables 
)

Redistribute the data contained in the internal buffers. \ solution += weight*dm

void EBLevelRedist::redistribute ( LevelData< EBCellFAB > &  a_solution,
const Interval a_srcVar,
const Interval a_dstVar 
)

version where solution is not necessarily ncomp long. intervals have to be the same length. srcVar can be up to m_ncomp long. dstVar can be up to solution.nComp().

void EBLevelRedist::fixExplicitLap ( const LevelData< EBCellFAB > &  a_kappaLap,
LevelData< EBCellFAB > &  a_solution,
const Interval variables 
)

Adjusts an explicit Laplacian calculation so that: a_solution_i = kappa_i*lap_i + (1-kappa_i)*sum_s(kappa_s*lap_s)/(sum_s kappa_s) where s is the set of cells neighboring, but not including i NOTE: a_solution must be passed in equal to a_kappaLap

bool EBLevelRedist::isDefined (  )  const

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

void EBLevelRedist::setToZero (  ) 

Reset the mass buffers of the class.

void EBLevelRedist::operator= ( const EBLevelRedist a_stenin  )  [inline, private]
