Constructor & Destructor Documentation

EBStencil::~EBStencil ( )

Destructor

◆ EBStencil() [1/4]

EBStencil::EBStencil ( const Vector< VolIndex > &  a_srcVofs,
const BaseIVFAB< VoFStencil > &  a_vofstencil,
const Box a_box,
const EBISBox a_ebisbox,
const IntVect a_ghostVectPhi,
const IntVect a_ghostVectLph,
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

◆ EBStencil() [2/4]

EBStencil::EBStencil ( const Vector< VolIndex > &  a_srcVofs,
const Vector< VoFStencil > &  a_vofStencil,
const Box a_boxLph,
const Box a_boxPhi,
const EBISBox a_ebisBoxLph,
const EBISBox a_ebisBoxPhi,
const IntVect a_ghostVectLph,
const IntVect a_ghostVectPhi,
int  a_varDest = 0,
int  ncomp = 1,
IntVectSet  a_setIrreg = IntVectSet(),
bool  a_useInputSets = false 
)

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

Member Function Documentation

◆ apply() [1/3]

void EBStencil::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

◆ apply() [2/3]

void EBStencil::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.

◆ apply() [3/3]

void EBStencil::apply ( EBCellFAB a_lofphi,
const EBCellFAB a_phi,
const Real  a_lambdaFactor,
const Real  a_alpha,
const BaseIVFAB< Real > &  a_alphaWeight,
const Real  a_beta,

◆ applyInhomDomBC()

void EBStencil::applyInhomDomBC ( EBCellFAB a_lofphi,
const EBCellFAB a_phi,
const Real  a_factor 
) const

◆ relax()

void EBStencil::relax ( EBCellFAB a_phi,
const EBCellFAB a_rhs,
const BaseIVFAB< Real > &  a_alphaWeight,
const BaseIVFAB< Real > &  a_betaWeight,
Real  a_alpha,
Real  a_beta,
Real  a_safety

const BaseIVFAB< Real > &  a_alphaWeight,
const BaseIVFAB< Real > &  a_betaWeight,
Real  a_alpha,
Real  a_beta,
Real  a_safety 
) const

◆ cache()

void EBStencil::cache ( const EBCellFAB a_lphi,
int  a_ivar = 0 
) const

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

◆ cachePhi()

void EBStencil::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

◆ uncache()

void EBStencil::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

◆ uncachePhi()

void EBStencil::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

◆ computeOffsets()

void EBStencil::computeOffsets ( const Vector< VolIndex > &  a_srcVoFs,
const BaseIVFAB< VoFStencil > &  a_vofstencil 
)

Compute integer offsets for stencil operations
