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

weak construction is bad.
