Detailed Description

Functor to compute divB into mf_out.

Constructor & Destructor Documentation

DivBFunctor::DivBFunctor	(	const std::array< const amrex::MultiFab *const, 3 >	arr_mf_src,
		const int	lev,
		amrex::IntVect	crse_ratio,
		const int	ncomp = `1`
	)

Constructor.

Parameters

[in]	arr_mf_src	source multifabs (3 elements for x y z).
[in]	lev	level of multifab.
[in]	crse_ratio	for interpolating field values from simulation MultiFabs to the output diagnostic MultiFab, mf_dst.
[in]	ncomp	Number of component of mf_src to cell-center in dst multifab.

overridevirtual

Compute DivB directly into mf_dst.

Parameters

[out]	mf_dst	output MultiFab where the result is written
[in]	dcomp	first component of mf_dst in which cell-centered data is stored

std::array<const amrex::MultiFab * const, 3> DivBFunctor::m_arr_mf_src

private

Vector of pointer to source multifab Bx, By, Bz

int const DivBFunctor::m_lev

private

level on which mf_src is defined (used in cylindrical)
