The generation of 3D, stretched, viscous unstructured meshes for arbitrary domains

Abstract

This paper presents a procedure which can generate highly stretched, unstructured, viscous meshes for essentially arbitrary three dimensional configurations. The procedure is based on a combination of the ideas behind Delaunay and moving front methodologies. Examples are presented for a variety of turbomachinery types of flow to demonstrate the potency of the new approach. Recent enhancements to the author's flow solver are also briefly described.
