Edge Equilibrium Code (EEC) For Tokamaks
Authors: Xujing Li, Leonid E. Zakharov, and Vladimir V. Drozdov
Abstract: The edge equilibrium code (EEC) described in this paper is developed for simulations of the near
edge plasma using the finite element method. It solves the Grad-Shafranov equation in toroidal
coordinate and uses adaptive grids aligned with magnetic field lines. Hermite finite elements are
chosen for the numerical scheme. A fast Newton scheme which is the same as implemented in the
equilibrium and stability code (ESC) is applied here to adjust the grids.
