Abstract
In this paper we propose an iterative scheme for a nonlinear spherical geodynamo model and carry out convergence analysis of this scheme. Our model is a coupled system of fluid velocity u , total kinematic pressure P and magnetic field B . They are governed by the Navier–Stokes equations and the dynamo equations. Using the mathematical induction method and energy estimates, it is concluded that our iterative scheme converges in the L ∞(0, T; H 1) sense and in the L 2(0, T; H 2) sense.
