Abstract

The quest to determine accurately the stability of tearing and resistive interchange modes in 2-dimensional toroidal geometry led to the development of the PEST-3 code, which is based on solving the singular, zero-frequency ideal magnetohydrodynamic (MHD) equation in the plasma bulk and determining the outer data Delta', Gamma' and Alpha' needed to match the outer region solutions to those arising in the inner layers. No assumptions regarding the aspect ratio, the number of rational surfaces or the pressure are made a priori. This approach is numerically less demanding than solving the full set of resistive equations and has the major advantage of allowing for non-MHD theories of the non-ideal layers.
