Detailed Description

specialization of aggstencil for variable coefficient elliptic operators. Real* dataPtr(int dataType, int ivar);

sten_t classes need the following functions srcIndex_t index(int isten) Real weight(int isten)

Constructor & Destructor Documentation

VCAggStencil::VCAggStencil ( const Vector< RefCountedPtr< BaseIndex > > &  a_dstVoFs,
const Vector< RefCountedPtr< BaseStencil > > &  a_stencil,
const EBCellFAB a_phiData,
const EBCellFAB a_rhsData,
const EBCellFAB a_relCoef,
const BaseIVFAB< Real > &  a_alphaDiagWeight,
const int &  a_ncomp 
)

a_dstIndex is where the answers will go. a_srcStencil is the stencil into the src data a_phiData is to provide offsets for source data (can be a dummy but must be the right size) a_rhsData is to provide offsets for destin data (can be a dummy but must be the right size) ncomp is the number of components in the cache rhsData and phiData can have the wrong number of comps

disallowed operators. Without code because Jeffster says that is better.

weak construction is bad.
