Several three dimensional primitives are presented that automatically subdivide any region bounded by six surfaces into polyhedrons. Each polyhedron is then meshed using the mapped mesh technique to generate hexahedron elements. The only input is the boundary edge definition and number of elements on each boundary edge- line. Linearly-blended Coons interpolation formulas are used to represent the six boundary surfaces. The final mesh is smoothed to provide an optimum grid. Several examples are presented.
