Abstract : Delaunay-Voronoi mesh systems provide a generalization of the classical rectangular staggered meshes to unstructured meshes. In this work it is shown how such covolume discretizations may be applied to div-curl systems in three dimensions. Error estimates are proved and confirmed by a numerical illustration. (AN)
