Internal Variables

Collaboration diagram for Internal Variables:

Modules
	Fourier representation
	Interface geometry: iRbc, iZbs etc.
	The Fourier harmonics of the interfaces are contained in iRbc(1:mn,0:Mvol) and iZbs(1:mn,0:Mvol), where iRbc(l,j), iZbs(l,j) contains the Fourier harmonics, \(R_j\), \(Z_j\), of the \(l\)-th interface.
	Fourier Transforms
	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.
	Volume-integrated Chebyshev-metrics
	These are allocated in dforce(), defined in ma00aa(), and are used in matrix() to construct the matrices.
	Vector potential and the Beltrami linear system
	Field matrices: dMA, dMB, dMC, dMD, dME, dMF
	Construction of "force"
	The force vector is comprised of Bomn and Iomn.
	Covariant field on interfaces: Btemn, Bzemn, Btomn, Bzomn
	The covariant field.
	covariant field for Hessian computation: Bloweremn, Bloweromn
	Geometrical degrees-of-freedom: LGdof, NGdof
	The geometrical degrees-of-freedom.
	Parallel construction of derivative matrix
	Derivatives of multiplier and poloidal flux with respect to geometry: dmupfdx
	Trigonometric factors
	Volume integrals: lBBintegral, lABintegral
	Internal global variables
	internal global variables; internal logical variables; default values are provided here; these may be changed according to input values
	Miscellaneous
	The following are miscellaneous flags required for the virtual casing field, external (vacuum) field integration, ...
