Constructor & Destructor Documentation

EBLevelRedist() [1/4]

EBLevelRedist::EBLevelRedist

(

)

Default constructor. User must subsequently call define().

~EBLevelRedist()

EBLevelRedist::~EBLevelRedist

(

)

EBLevelRedist() [2/4]

EBLevelRedist::EBLevelRedist	(	const DisjointBoxLayout &	a_dbl,
		const EBISLayout &	a_ebisl,
		const ProblemDomain &	a_domain,
		const int &	a_ncomp,
		int	a_redistRad = 1,
		bool	a_do2DStencil = false
	)

Defining constructor. Constructs a valid object. Equivalent to default construction followed by define(). ebisl needs ghost cells out to 3*redistradius of the stencil. This sets the stencil to volume-weighted. Use resetWeights to set to mass weighted or whatever.

define() [1/2]

void EBLevelRedist::define	(	const DisjointBoxLayout &	a_dbl,
		const EBISLayout &	a_ebisl,
		const ProblemDomain &	a_domain,
		const int &	a_ncomp,
		int	a_redistRad = 1,
		bool	a_do2DStencil = false
	)

Defines this object. Existing information is overriden. ebisl needs ghost cells out to 3*redistradius

define() [2/2]

void EBLevelRedist::define ( const EBLevelGrid &  a_eblg, const int &  a_ncomp, int  a_redistRad = 1, bool  a_do2DStencil = false  )

resetWeights()

void EBLevelRedist::resetWeights	(	const LevelData< EBCellFAB > &	modifier,
		const int &	ivar
	)

Modify the weights in the stencil by multiplying by the inputs in a normalized way. If you want mass weighting, send in the density.

Referenced by define().

increment() [1/2]

void EBLevelRedist::increment	(	const BaseIVFAB< Real > &	massDiff,
		const DataIndex &	datInd,
		const Interval &	variables
	)

Store the input mass difference in the buffers of the class by INCREMENTING the buffer. \ dm += massDiff

redistribute() [1/2]

void EBLevelRedist::redistribute	(	LevelData< EBCellFAB > &	solution,
		const Interval &	variables
	)

Redistribute the data contained in the internal buffers. \ solution += weight*dm

Referenced by increment().

redistribute() [2/2]

void EBLevelRedist::redistribute	(	LevelData< EBCellFAB > &	a_solution,
		const Interval &	a_srcVar,
		const Interval &	a_dstVar
	)

version where solution is not necessarily ncomp long. intervals have to be the same length. srcVar can be up to m_ncomp long. dstVar can be up to solution.nComp().

fixExplicitLap()

void EBLevelRedist::fixExplicitLap	(	const LevelData< EBCellFAB > &	a_kappaLap,
		LevelData< EBCellFAB > &	a_solution,
		const Interval &	variables
	)

Adjusts an explicit Laplacian calculation so that: a_solution_i = kappa_i*lap_i + (1-kappa_i)*sum_s(kappa_s*lap_s)/(sum_s kappa_s) where s is the set of cells neighboring, but not including i NOTE: a_solution must be passed in equal to a_kappaLap

isDefined()

bool EBLevelRedist::isDefined

(

)

const

Returns true if this object was created with the defining constructor or if define() has been called.

setToZero()

void EBLevelRedist::setToZero

(

)

Reset the mass buffers of the class.
