A new highly efficient two-step algorithm for the stationary incompressible magnetohydrodynamic equations is studied in this paper. The algorithm uses a lower order finite element pair (ie, P 1 b− P 1− P 1) to compute an initial approximation, that is using the Mini-element (ie, P 1 b− P 1) to approximate the velocity and pressure and P 1 element to approximate the magnetic field, then applies a higher order finite element pair (ie, P 2− P 1− P 2) to solve a linear system on the same mesh. Furthermore, the convergence analyses of standard Galerkin finite element method and the two-step algorithm are addressed. Lastly, numerical experiments are presented to verify both the theory and the efficiency of the algorithm.
