◆ fourier_construct()

class (fourier_class) function, pointer fourier::fourier_class::fourier_construct	(	integer, intent(in)	mpol,
		integer, intent(in)	ntor,
		integer, intent(in)	ntheta,
		integer, intent(in)	nzeta,
		integer, intent(in)	nfp,
		logical, intent(in)	sym
	)

Construct a fourier_class object..

Allocates memory and initializes a fourier_class object. Computes the othronorm and cosine and sine buffers.

This subroutine computes the cosine-sine factors that will be needed when moving between Fourier and real space. All normalizations are contained in the poloidal quantities used in the Fourier to real space transformation:

sinmui
cosmui

Fourier representations are assumed to have stellarator symmetry: *# cosine (iparity=0): C(u, v) = sum_u sum_v (C_mn COS(mu + n*nfp*v)) *# sine (iparity=1): S(u, v) = sum_u sum_v (S_mn SIN(mu + n*nfp*v))

The number of collocation points have been set initalially equal to the number of modes: theta_j = j*pi/M, j = 0,...,M Where M = mpol - 1 zeta_k = k*2*pi/(2N + 1) k = 0,...,2N Where N = ntor.

Parameters

[in]	mpol	Number of poloidal modes.
[in]	ntor	Number of toroidal modes.
[in]	ntheta	Number of poloidal real grid points.
[in]	nzeta	Number of toroidal real grid points.
[in]	nfp	Number of field periods.
[in]	sym	Symmetry flag.
