The coordinate geometry and fields are mapped to/from Fourier space and real space using FFTW3. The resolution of the real space grid is given by Nt=Ndiscrete*4*Mpol and Nz=Ndiscrete*4*Ntor.
Various workspace arrays are allocated. These include Rij(1:Ntz,0:3,0:3) and Zij(1:Ntz,0:3,0:3), which contain the coordinates in real space and their derivatives; sg(0:3,Ntz), which contains the Jacobian and its derivatives; and guv(0:6,0:3,1:Ntz), which contains the metric elements and their derivatives.
