Global resistive MHD calculations for high-beta DIII-D divertor tokamak

Abstract

In the dielectric-in-cell code, a grid is laid over the cloud, the dc dielectric constant b estimated on this grid from the positions of the dielectric elements, and then the polarization charge density and the polarisation electric field are obtained on the grid by iteratively solving Poisson's equation. The positions of the dielectric elements are then advanced in time by having them $ x d drift in the gidded
