Abstract

This paper discusses the development of the MHD stability code PEST which allows computation of tearing and resistive interchange modes in two-dimensional toroidal geometry. This approach provides a numerical solution which proves to be less demanding than solving the full set of resistive equations and has the advantage of allowing for non-MHD theories of non-ideal layers. Good convergence is ensured by the variational Galerkin scheme used to compute the outer matching data. The growth rate calculations of resistive kink modes are presented and are in good agreement with those obtained by the full resistive MHD code MARS.
