Numerical solution of linearized resistive MHD equations in a cylindrical geometry

Linearized resistive MHD eigenequations in a cylindrical geometry are derived and numerical methods are presented. The eigenequations are solved in a global manner such that there is no need to distinguish inner resistive layer and outer ideal region analytically. Resistive layer is numerically treated by using non-uniform mesh grid technique and high accuracy discretization scheme. Lundquist number S up to 109 can be easily achieved. Numerical results are benchmarked by known analytical solutions and other numerical methods. 6 refs, 5 figs
