# A computer model for resistive MHD analysis

## Description

Abstract This paper describes the formulation of a linear MHD stability code in toroidal geometry. The only assumption involved is that the perturbations are incompressible. The emphasis is to construct a code capable of calculating the effects of finite plasma resistivity. Thus, a magnetic flux coordinate system is employed since resistivity is known to be important in narrow regions in the vicinity of resonant magnetic surfaces. The code is constructed as an initial value problem, using fully implic...
