SUMMARYA description is given of a method capable of automatically forming e cient, high-quality hybrid meshes for viscous ow calculations over complete aircraft, given engineers' requirements on mesh density and ÿrst cell-height. Mixed quadrilateral=triangular surface grids are constructed using the moving-front approach, with point placement and connection optimized to ensure high-quality, anisotropic panels are generated. The volume mesh is built in two stages. A near ÿeld mesh is formed using the advancinglayer approach, signiÿcantly enhanced through the use of mesh enriching=collapsing techniques and layer-intersection detection=front-termination algorithms. The remainder of the domain is then covered by a cut-cell Cartesian mesh of varying density that conforms to the outer-surface of the near ÿeld mesh. Examples of meshes generated using the described methods are presented and the user-input discussed.

Computational fluid dynamics (CFD) tools are an integral part of the processes within design and performance assessment offices in the aerospace industry. As timescales from initial concept to design-freeze become shorter, there is an increasing need for the CFD process to be timely and cost effective and for confidence in the predictive capability of the CFD tool to be high. Only in this way will the impact of CFD be maximised. The CFD software development and support team plays a key role in achieving this goal. This paper describes how the team at ARA has met the challenge of delivering to industry what it requires in terms of both the CFD tools and the people who supply them. The qualities needed to do this extend beyond the ability to achieve technical advancement, although prime emphasis is still placed on this aspect. In particular, the importance of developing a close relationship between CFD team and end user — an integrated team approach — is stressed. This leads to a precise and unambiguous understanding of customer needs and the delivery of the required product and its maintenance. The demonstration of recent technical achievements and the discussion of supporting team attributes exemplify these points.
