A Fully Two-Dimensional Equilibrium and Transport Model of the Poloidal Divertor.

Abstract

We have developed a fully two-dimensional Eulerian-Lagrangian nonideal MHD simulation model of tokamak discharges. The code is designed to simultaneously follow the resistive diffusion transport and gross dynamics of a magnetically confined plasma of arbitrary shape. It uses as a finite-difference mesh a general connectivity triangular grid. the triangular grid is the natural choice for a finite-difference mesh for modeling complicated geometries with interfaces, multiple magnetic axes and separatrices. We present here the methods we have developed to calculate equilibria and transport in a fully two-dimensional geometry. The model is sufficiently general that is capable of calculating equilibria and transport given rather general plasma geometries and coil structures. Here we apply the model to the poloidal divertor system and describe the results.
