cube_init()

subroutine, public cube_oct_m::cube_init	(	type(cube_t), intent(out)	cube,
		integer, dimension(:), intent(in)	nn,
		type(namespace_t), intent(in)	namespace,
		class(space_t), intent(in)	space,
		real(real64), dimension(:), intent(in)	spacing,
		class(coordinate_system_t), intent(in)	coord_system,
		integer, intent(in), optional	fft_type,
		integer, intent(in), optional	fft_library,
		logical, intent(in), optional	dont_optimize,
		integer, dimension(3), intent(out), optional	nn_out,
		type(mpi_grp_t), intent(in), optional	mpi_grp,
		logical, intent(in), optional	need_partition,
		real(real64), dimension(3), intent(in), optional	tp_enlarge,
		integer, intent(in), optional	blocksize
	)

Parameters

[in]	fft_type	Is the cube going to be used to perform FFTs?
[in]	fft_library	What fft library to use
[in]	dont_optimize	if true, do not optimize grid for FFT
[out]	nn_out	What are the FFT dims? If optimized, may be different from input nn.
[in]	mpi_grp	The mpi group to be use for cube parallelization
[in]	need_partition	Should we calculate and store the cube partition?
[in]	tp_enlarge	Two point enlargement factor. Can be used with (p)nfft enlarge the box by moving outward the cube first and last points in each direction. The resulting boundaries are rescaled by tp_enlarge.
[in]	blocksize	just use a fixed block decomposition without caring about FFT library. See description for cube_set_blocksize.
