Detailed Description

Base class for passing domain boundary conditions into EBHelmholtzOp.

Member Function Documentation

define()

void EBHelmholtzDomainBC::define ( const Location::Cell  a_dataLocation, const EBLevelGrid &  a_eblg, const RealVect &  a_probLo, const Real  a_dx  )

virtual

Define function.

Parameters

[in]	a_eblg	Level grids
[in]	a_probLo	Lower-left corner of computational domain
[in]	a_dx	Grid resolution

Note

This sets the internals for the BC object. This is called by EBHelmholtzOp when it defines stencils.

Reimplemented in EBHelmholtzElectrostaticDomainBC, and EBHelmholtzEddingtonSP1DomainBC.

getBoundaryPosition()

RealVect EBHelmholtzDomainBC::getBoundaryPosition ( const IntVect &  a_iv, const int &  a_dir, const Side::LoHiSide &  a_side  ) const

inlineprotected

Returns the cell-centered position at the boundary.

Parameters

[in]	a_iv	Grid cell
[in]	a_dir	Face coordinate direction
[in]	a_side	Lo/Hi side

getFaceFlux() [1/2]

virtual void EBHelmholtzDomainBC::getFaceFlux ( BaseFab< Real > &  a_faceFlux, const BaseFab< Real > &  a_phi, const BaseFab< Real > &  a_Bcoef, const int &  a_dir, const Side::LoHiSide &  a_side, const DataIndex &  a_dit, const bool  a_useHomogeneous  ) const

pure virtual

Get face flux. This is for regular cells.

Parameters

[in,out]	a_faceFlux	Face-centered flux.
[in]	a_phi	Cell-centered data
[in]	a_Bcoef	Face-centered B-coefficient
[in]	a_dir	Coordinate direction
[in]	a_side	High or low side
[in]	a_dit	Data index
[in]	a_useHomogeneous	Homogeneous physical BCs or not.

Note

a_faceFlux is defined in the first strip of interior cells on the (dir,side) edge of the domain.

Implemented in EBHelmholtzDirichletDomainBC, EBHelmholtzNeumannDomainBC, EBHelmholtzRobinDomainBC, EBHelmholtzElectrostaticDomainBC, and EBHelmholtzEddingtonSP1DomainBC.

getFaceFlux() [2/2]

virtual Real EBHelmholtzDomainBC::getFaceFlux ( const VolIndex &  a_vof, const EBCellFAB &  a_phi, const EBFaceFAB &  a_Bcoef, const int &  a_dir, const Side::LoHiSide &  a_side, const DataIndex &  a_dit, const bool  a_useHomogeneous  ) const

pure virtual

Get face flux. This is for irregular cells.

Parameters

[in]	a_vof	Grid cell
[in]	a_phi	Cell-centered data
[in]	a_Bcoef	Face-centered B-coefficient
[in]	a_dir	Coordinate direction
[in]	a_side	High or low side
[in]	a_dit	Data index
[in]	a_useHomogeneous	Homogeneous physical BCs or not.

Implemented in EBHelmholtzDirichletDomainBC, EBHelmholtzNeumannDomainBC, EBHelmholtzRobinDomainBC, EBHelmholtzElectrostaticDomainBC, and EBHelmholtzEddingtonSP1DomainBC.

multiplyByBcoef()

void EBHelmholtzDomainBC::multiplyByBcoef ( BaseFab< Real > &  a_flux, const BaseFab< Real > &  a_bco, const int  a_dir, const Side::LoHiSide  a_side  ) const

protected

Utility function which multiplies the flux (or actually, dphi/dn) by the B-coefficient. This is used by the implementation classes when they compute the regular flux at the domain edges/faces.

Parameters

[in,out]	a_flux	On input, contains dphi/dn. On output, contains B*dphi/dn
[in]	a_bco	Helmholtz B-coefficient
[in]	a_dir	Coordinate direction
[in]	a_side	Side

Note

This routine is weird because the flux data holder in the BC classes lives on the cell centers next to the domain face/edge. So we need to shift the box over when we multiply. Because both Dirichlet, Neumann, and the Robin Bcs need to do this, I'm putting this routine in the parent class.
