Functions
amrex::Vector< int >	column_bands (const amrex::BoxArray &ba)
void	fill_below_band (amrex::MultiFab &mf, int icomp, int ncomp, int klo_band, const amrex::IntVect &lateral_ng, const amrex::Geometry &geom)

Function Documentation

column_bands()

amrex::Vector<int> column_bands

(

const amrex::BoxArray &

ba

)

The distinct lowest z indices of the boxes of a BoxArray, bottom up.

Parameters

[in]

ba

BoxArray of the level

Returns

lowest z index of every band of boxes, in increasing order

fill_below_band()

void fill_below_band	(	amrex::MultiFab &	mf,
		int	icomp,
		int	ncomp,
		int	klo_band,
		const amrex::IntVect &	lateral_ng,
		const amrex::Geometry &	geom
	)

Fill the cells just below the boxes of mf whose lowest z index is klo_band, widened laterally by lateral_ng, from the boxes of mf below that band, which must already have been integrated. A cell inside a box below takes that box's value; otherwise a cell in the lateral ghost region of a box below takes the value that box holds there. A cell with no box of mf below it (e.g. under a refined patch that does not reach the ground) keeps the value it has.

Parameters

[in,out]	mf	field being integrated; needs lateral_ng ghost cells plus one in z
[in]	icomp	first component to fill
[in]	ncomp	number of components to fill
[in]	klo_band	lowest z index of the band about to be integrated
[in]	lateral_ng	lateral width of the filled slabs; its z entry must be zero
[in]	geom	geometry of the level (lateral periodicity is honoured)
