The following paper examines the key aspects of technology that deliver an advanced hybrid meshing capability that is operational today, and is ideally suited to complex, realworld geometries. The paper shows how particular benefits are derived from detailed algorithmic features at octree level, from the overall meshing procedure and from the software's client-server architecture and its distributed-memory parallel implementation. Two two complex geometry examples are used to demonstrate the benefits in terms of complex geometry capability, of ability to modify geometry and of and ease-of-use. Nomenclature ϕ = distance field derived around the surfaces defining the geometry 1
