    Hexahedral mesh generation for three-dimensional solid objects is often done in stages. Usually an object is first subdivided into simple-shaped subregions, which then are filled with hexahedral finite elements. This article presents an automatic subdividing method of polyhedron with planar faces. The subdivision is based on medial surface, axes and nodes of a solid. The main emphasis is put on creating a topology of subregions. Obtaining such a topology involves defining a graph structure OMG which contains necessary information about medial surface topology and object topology, followed by simple symbolic processing on it.
