The three-dimensional Variational Moments Equilibrium Code (VMEC) minimizes the energy functional

over the toroidal domain ωp. The solution is obtained in flux coordinates (s, θ, ζ), related to the cylindrical coordinates (R, φ, Z) by

The code assumes nested flux surfaces. [1] [2]

Implementations of the code

The code is being used at:

  • ORNL, Oak Ridge, TN, USA (code origin)
  • IPP, Garching, Germany
  • CRPP, Lausanne, Switzerland
  • NIFS, Japan
  • LNF, Spain

Enhancements / extensions of the code

  • DIAGNO, [3] to calculate the response of magnetic diagnostics
  • MFBE [4]
  • STELLOPT [5]
