Grid-based mesh generation methods have been available for many
years and can provide a reliable method for meshing arbitrary geometries with
hexahedral elements. The principal use for these methods has mostly been limited
to biological-type models where topology that may incorporate sharp edges and
curve definitions are not critical. While these applications have been effective, robust
generation of hexahedral meshes on mechanical models, where the topology is
typically of prime importance, impose difficulties that existing grid-based methods
have not yet effectively addressed. This work introduces a set of procedures that
can be used in resolving the features of a geometric model for grid-based hexahedral
mesh generation for mechanical or topology-rich models.
