Member Function Documentation

void EBFineToCoarRedist::resetWeights ( const LevelData< EBCellFAB > &  a_modifierCoar,
const int &  a_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 on the coarse layout.

void EBFineToCoarRedist::define ( const DisjointBoxLayout a_dblFine,
const DisjointBoxLayout a_dblCoar,
const EBISLayout a_ebislFine,
const EBISLayout a_ebislCoar,
const Box a_domainCoar,
const int &  a_nref,
const int &  a_nvar,
int  a_redistRad = 1,
const EBIndexSpace *const   a_ebisPtr = Chombo_EBIS::instance() 
)

uglier but general define fcn

Full define function. Define the stencils with volume weights. If you want mass weights or whatever, use reset weights.

void EBFineToCoarRedist::define ( const EBLevelGrid a_eblgFine,
const EBLevelGrid a_eblgCoar,
const int &  a_nref,
const int &  a_nvar,
const int &  a_redistRad 
)

potentially faster define function, especially with large numbers of boxes.

void EBFineToCoarRedist::setToZero (  ) 

Initialize values of registers to zero.

void EBFineToCoarRedist::increment ( const BaseIVFAB< Real > &  a_fineMass,
const DataIndex a_fineDataIndex,
const Interval a_variables 
)

Increments the register with data from coarseMass. This is the full redistribution mass. Internally the class figures out what actually goes to the coarse level.

void EBFineToCoarRedist::redistribute ( LevelData< EBCellFAB > &  a_coarSolution,
const Interval a_variables 
)

Redistribute the data contained in the internal buffers.
