Member Function Documentation

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 Real &  a_beta, 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 MFHelmholtzEBBC, EBHelmholtzRobinEBBC, EBHelmholtzNeumannEBBC, and EBHelmholtzDirichletEBBC.

define()

void EBHelmholtzEBBC::define	(	const Location::Cell	a_dataLocation,
		const EBLevelGrid &	a_eblg,
		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_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
