◆ applyEBFlux()

virtual void EBHelmholtzEBBC::applyEBFlux	(	VoFIterator &	a_vofit,
		EBCellFAB &	a_Lphi,
		const EBCellFAB &	a_phi,
		const BaseIVFAB< Real > &	a_Bcoef,
		const DataIndex &	a_dit,

		const bool &	a_homogeneousPhysBC
	)		const

pure virtual

Apply the EB flux. This is the version that is called by EBHelmholtzOp.

Parameters

[in,out]	a_vofit	Iterator for cut-cells
[in]	a_Lphi	Operator kappa*L(phi)
[in]	a_phi	Phi, cell-centered.
[in]	a_Bcoef	EB-centered B-coefficient
[in]	a_dit	Data index
[in]	a_beta	Beta. Passed in from operator.
[in]	a_homogeneousPhysBC	Homogeneous BC or not.

Implemented in EBHelmholtzDirichletEBBC, EBHelmholtzNeumannEBBC, EBHelmholtzRobinEBBC, and MFHelmholtzEBBC.

◆ define() [1/2]

virtual void EBHelmholtzEBBC::define ( )

protectedpure virtual

User define function.

Implemented in EBHelmholtzDirichletEBBC, EBHelmholtzNeumannEBBC, EBHelmholtzRobinEBBC, and MFHelmholtzEBBC.

◆ define() [2/2]

void EBHelmholtzEBBC::define	(	const Location::Cell	a_dataLocation,
		const EBLevelGrid &	a_eblg,
		const AmrMask &	a_validCells,
		const RealVect &	a_probLo,
		const Real &	a_dx,
		const int	a_ghostCF
	)

Define function that is called by EBHelmholtzOp.

Parameters

[in]	a_dataLocation	Specification of data centering
[in]	a_eblg	Grid where this object is defined.
[in]	a_validCells	Valid grid cells (might be null pointer)
[in]	a_probLo	Lower-left corner of computational domain. Required if BC objects needs physical position.
[in]	a_dx	Grid resolution.
[in]	a_ghostCF	Number of ghost cells that are filled across CF interface.

◆ getGradPhiStencils()

const LayoutData< BaseIVFAB< VoFStencil > > & EBHelmholtzEBBC::getGradPhiStencils ( ) const

Get the stencil for computing the finite-volume approximation to kappa*Div(F).

The finite volume approximation to kappa*Div(F) is sum(Fluxes)/dx. This routine should return the flux on the EB, i.e. (B*dphi/dn)/dx. The derivative can be written dphi/dn = w0*phi0 + sum(wi*phi(i)) where phi0 is a boundary weight and phi(i) are grid points. This routine should return the stencil B*wi*phi(i).

Note: Multiplication by beta is done in the operator.

◆ isStencilValidCF()

bool EBHelmholtzEBBC::isStencilValidCF	(	const VoFStencil &	a_stencil,
		const DataIndex &	a_dit
	)		const

inlineprotected

Check if stencil is valid.

This routine makes sure that the stencil a_stencil does not reach over the CF interface and into ghost cells that do not have valid data.

Parameters

[in]	a_stencil	Stencil
[in]	a_dit	Data index
