Résumé

We present the convergence analysis of locally divergence-free discontinuous Galerkin methods for the induction equations which appear in the ideal magnetohydrodynamic system. When we use a second order Runge Kutta time discretization, under the CFL condition $Δ t \sim h^{4 / 3}$ , we obtain error estimates in $L^{2}$ of order $𝒪 (Δ t^{2} + h^{m + 1 / 2})$ where $m$ is the degree of the local polynomials.
