Detailed Description

Very slow, bad version of EB stencil.

Slow version of the stencil used only to illustrate just how good an idea aggregation is. It also could be useful for debugging if an issue ever comes up with the aggregated version. Under no circumstances should this class be used as anything but as an educational or debugging tool. Using this will absolutely destroy your performance. Really.

NonAggregatedEBStencil::~NonAggregatedEBStencil (  ) 

Destructor

NonAggregatedEBStencil::NonAggregatedEBStencil ( const Vector< VolIndex > &  a_srcVofs,
const BaseIVFAB< VoFStencil > &  a_vofstencil,
const Box a_box,
const EBISBox a_ebisbox,

int  a_varDest = 0,
bool  a_doRelaxOpt = false,
int  ncomp = 1,
IntVectSet  a_setIrreg = IntVectSet(),
bool  a_useInputSets = false 
)

Full constructor. Box is unghosted. When setting Lphi(i,j) = L(phi(i,j)) GhostVectPhi is the ghost vect of phi GhostVectLph is the ghost vect of lphi

Second constructor for creating stencil where dest and src live on 2 different levels and dest is Lphi and src is Phi. no relax optimization here

void NonAggregatedEBStencil::apply ( EBCellFAB a_lofphi,
const EBCellFAB a_phi,
bool  incrementOnly = false,
int  ivar = 0 
) const

Applies stencil to each component of phi using the stencil weights and offsets to compute L. If incrementOnly = true, a_lofphi is incremented without any set to zero. If false, a_lofphi is set to zero and set equal to L(phi). ivar is so you can apply a scalar ebstencil to a component of a larger holder

void NonAggregatedEBStencil::apply ( EBCellFAB a_lofphi,
const EBCellFAB a_phi,
const BaseIVFAB< Real > &  a_alphaWeight,
Real  a_alpha,
Real  a_beta,
bool  incrementOnly = false 
) const

Applies stencil to each component of phi using the stencil weights and offsets to compute L. but with constants. a_lofphi_i = alpha*phi_i + beta*lphi_i If incrementOnly = true, a_lofphi is incremented without any set to zero. If false, a_lofphi is set to zero and set equal to a_lofphi_i Alpha and beta are defined over getIrregIVS(lphBox) where lphBox = grow(a_box, a_ghostVectLph) where a_box are given in the constructor.

void NonAggregatedEBStencil::cache ( const EBCellFAB a_lphi,

Cache lphi. ivar is so you can apply a scalar ebstencil to a component of a larger holder

void NonAggregatedEBStencil::cachePhi ( const EBCellFAB a_lphi,
int  a_ivar = 0 
) const

Cache phi ivar is so you can apply a scalar ebstencil to a component of a larger holder

void NonAggregatedEBStencil::uncache ( EBCellFAB a_lphi,
int  a_ivar = 0 
) const

Uncache lphi ivar is so you can apply a scalar ebstencil to a component of a larger holder

void NonAggregatedEBStencil::uncachePhi ( EBCellFAB a_phi,
int  a_ivar = 0 
) const

Uncache phi ivar is so you can apply a scalar ebstencil to a component of a larger holder
