Function Documentation

FirstOrderExtrap() [1/2]

void amrex::Extrapolater::FirstOrderExtrap	(	MultiFab &	mf,
		const Geometry &	geom,
		int	scomp,
		int	ncomp
	)

Extrapolate cell-centered data outward one cell to fill boundary conditions.

Parameters

mf	MultiFab whose ghost cells will be filled.
geom	Geometry describing the level (used for domain bounds).
scomp	Starting component index in mf.
ncomp	Number of components to extrapolate.

Note

FillBoundary (with periodicity) should be called on mf before invoking this routine.

FirstOrderExtrap() [2/2]

void amrex::Extrapolater::FirstOrderExtrap	(	MultiFab &	mf,
		const Geometry &	geom,
		int	scomp,
		int	ncomp,
		int	nGrow
	)

Overload that extrapolates into a caller-provided number of grow cells.

Parameters

mf	MultiFab whose ghost cells will be filled.
geom	Geometry describing the level.
scomp	Starting component index in mf.
ncomp	Number of components to extrapolate.
nGrow	Number of ghost cells to update (instead of using mf.nGrow()).
