Divergence-free MHD on unstructured meshes using high order finite volume schemes based on multidimensional Riemann solvers

The resulting divergence-free ADER-WENO schemes with MuSIC Riemann solvers give us an efficient and easily-implemented strategy for divergence-free MHD on unstructured meshes. Several stringent two- and three-dimensional problems are shown to work well with the methods presented here.
