HEXAHEDRAL MESH GENERATION BY MEDIAL SURFACE SUBDIVISION: PART II. SOLIDS WITH FLAT AND CONCAVE EDGES

A method is presented for the subdivision of a large class of solids into simple subregions suitable for automatic Þnite element meshing with hexahedral elements. The medial surface subdivision technique described previously in the literature is used as the basis for this work and is extended here to cover solids which have ßat and concave edges. Problems where the medial surface is degenerated are also addressed
