◆ poisson_fmm_init()

subroutine, public poisson_fmm_oct_m::poisson_fmm_init	(	type(poisson_fmm_t), intent(out)	this,
		class(space_t), intent(in)	space,
		type(derivatives_t), intent(in), target	der,
		type(mpi_comm), intent(in)	all_nodes_comm
	)

Initialises the FMM parameters and vectors. Also it calls to the library initialisation.

◆ poisson_fmm_end()

subroutine, public poisson_fmm_oct_m::poisson_fmm_end ( type(poisson_fmm_t), intent(inout) this )

Release memory and call to end the library.

◆ poisson_fmm_solve()

subroutine, public poisson_fmm_oct_m::poisson_fmm_solve	(	type(poisson_fmm_t), intent(in)	this,
		type(derivatives_t), intent(in), target	der,
		real(real64), dimension(:), intent(inout)	pot,
		real(real64), dimension(:), intent(in)	rho
	)

Both direct solvers and FMM calculate the Hartree potential via direct additions, without solving the Poisson equation itself. Direct solvers in any dimension does not require any initialization. However, fmm requires initialization because, in contrast to Octopus` direct solvers, FMM reads some parameters from the inp file.
