		bool	a_rhsAlreadyKappaWeighted = `false`
	)

Computes the time-centered diffusive term for explicit updating. This integrates the diffusion equation for a new value of a quantity phi and then computes the diffusion term using a finite difference stencil in time.

Parameters

a_diffusionTerm	The term computed by this method.
a_phiOld	The value of phi at the beginning of the time step, at the current grid level.
a_src	The source term in the diffusion equation at the current grid level.
a_fineFluxRegPtr	A pointer to the flux register at the finer adjacent grid level (or NULL if there is none).
a_crseFluxRegPtr	A pointer to the flux register at the coarser adjacent grid level (or NULL if there is none).
a_crsePhiOldPtr	A pointer to the LevelData object holding the old value of phi on the coarser adjacent grid level (or NULL if there is none).
a_crsePhiNewPtr	A pointer to the LevelData object holding the updated value of phi on the coarser adjacent grid level (or NULL if there is none).
a_oldTime	The time at the beginning of the integration step on the current grid level.
a_crseOldTime	The time at the beginning of the integration step on the coarser adjacent grid level.
a_crseNewTime	The time at the end of the integration step on the coarser adjacent grid level.
a_dt	The time step on the current grid level.
a_level	The current grid level.
a_zeroPhi	If this flag is true, the initial estimate of phi will be set to zero. Otherwise, a_phiOld will be used.

◆ updateSoln()

void EBLevelCrankNicolson::updateSoln	(	LevelData< EBCellFAB > &	a_phiNew,
		LevelData< EBCellFAB > &	a_phiOld,
		LevelData< EBCellFAB > &	a_src,
		EBFluxRegister *	a_fineFluxRegPtr,
		EBFluxRegister *	a_crseFluxRegPtr,

		Real	a_dt,
		int	a_level,
		bool	a_zeroPhi = `true`,
		bool	a_rhsAlreadyKappaWeighted = `false`,
		int	a_fluxStartComponent = `0`
	)

virtual

Integrates the diffusion equation, storing the result in a_phiNew.

Parameters

a_phiNew	The new value of phi at the current grid level.
a_phiOld	The value of phi at the beginning of the time step, at the current grid level.
a_src	The source term in the diffusion equation at the current grid level.
a_fineFluxRegPtr	A pointer to the flux register at the finer adjacent grid level (or NULL if there is none).
a_crseFluxRegPtr	A pointer to the flux register at the coarser adjacent grid level (or NULL if there is none).
a_crsePhiOldPtr	A pointer to the LevelData object holding the old value of phi on the coarser adjacent grid level (or NULL if there is none).
a_crsePhiNewPtr	A pointer to the LevelData object holding the updated value of phi on the coarser adjacent grid level (or NULL if there is none).
a_oldTime	The time at the beginning of the integration step on the current grid level.
a_crseOldTime	The time at the beginning of the integration step on the coarser adjacent grid level.
a_crseNewTime	The time at the end of the integration step on the coarser adjacent grid level.
a_dt	The time step on the current grid level.
a_level	The current grid level.
a_zeroPhi	If this flag is true, the initial estimate of phi will be set to zero. Otherwise, a_phiOld will be used.
