Toward peta-scale computing era, a next-generation MHD solver that is accurate and robust enough for any parameter regimes from almost incompressible turbulences to hypersonic flows should be developed. One of the key techniques for the next-generation solver must be a divergence cleaning method for the magnetic filed, which primarily affects the robustness of the multidimensional MHD solver particularly in high-resolution simulations. In this paper, several divergence cleaning methods including new methods are comparatively studied based on the HLLD Riemann solver.
