Detailed Description

template<typename MF = MultiFab>
class amrex::FFT::PoissonOpenBC< MF >

Poisson solve for Open BC using FFT.

Constructor & Destructor Documentation

PoissonOpenBC()

template<typename MF >

template<typename FA , std::enable_if_t< IsFabArray_v< FA >, int > FOO>

amrex::FFT::PoissonOpenBC< MF >::PoissonOpenBC ( Geometry const &  geom, IndexType  ixtype = IndexType::TheCellType(), IntVect const &  ngrow = IntVect(0)  )

explicit

Build an open-boundary FFT solver over the grown domain.

Parameters

geom	Geometry describing the problem domain.
ixtype	Index type (cell vs. node) for the working arrays.
ngrow	Number of grow cells applied prior to solving.

Member Function Documentation

define_doit()

template<typename MF >

void amrex::FFT::PoissonOpenBC< MF >::define_doit

(

)

Initialize the discretized Green's function cache (public for CUDA kernels).

solve()

template<typename MF >

void amrex::FFT::PoissonOpenBC< MF >::solve	(	MF &	soln,
		MF const &	rhs
	)

Solve the open-boundary Poisson problem.

Parameters

soln	Solution MultiFab (cell- or node-centered to match constructor).
rhs	Right-hand-side MultiFab.
