The authors present a computational code for solving two-dimensional, time-dependent magnetohydrodynamic (MHD) equations by the method of characteristics. The physical system under consideration is axisymmetric, with vφ = 0 and Bφ = 0. The numerical scheme is described in detail, and the results of calculations are compared with two analytic solutions of the MHD equations: (1) linearized, standing MHD wave motions in a magnetized cylindrical plasma; (2) nonlinear self-similar expansion of a magnetized plasma ball. In addition, the authors have studied the nonlinear development of standing MHD wave solutions in a cylindrical plasma.
