Ma. Price et Cg. Armstrong, HEXAHEDRAL MESH GENERATION BY MEDIAL SURFACE SUBDIVISION .2. SOLIDS WITH FLAT AND CONCAVE EDGES, International journal for numerical methods in engineering, 40(1), 1997, pp. 111-136
A method is presented for the subdivision of a large class of solids i
nto simple subregions suitable for automatic finite element meshing wi
th hexahedral elements. The medial surface subdivision technique descr
ibed previously in the literature is used as the basis for this work a
nd is extended here to cover solids which have flat and concave edges.
Problems where the medial surface is degenerated are also addressed.
