Current Research Work
Computational Aerodynamics
Dr. Ollivier-Gooch’s research group specializes in developing techniques for numerical solution of problems in aerodynamic. In particular, we are working to take advantage of both the geometric flexibility of unstructured mesh methods and the accuracy benefits of high-order methods. Recent work has exploited Newton-GMRES techniques to develop extremely efficient, high-order accurate methods for inviscid compressible aerodynamics problems, including showing that high-order methods can achieve solutions of engineering accuracy more quickly than second-order methods. Current work is focused on extending these results to viscous flows and on developing high-order accurate optimization techniques.
Unstructured Mesh Generation
Hand-in-hand with research in unstructured mesh flow solvers, Dr. Ollivier-Gooch’s group also studies unstructured mesh generation, which is the process of decomposing a domain into triangular or tetrahedral cells. Past work has included development of highly successful techniques for unstructured mesh improvement; and extension of meshing techniques with known mesh quality guarantees to allow better control of cell size in both two and three dimensions and to work with curved boundary data in two dimensions. Ongoing work includes generation of anisotropic meshes (especially for high Reynolds number viscous flows) and mesh generation from clean CAD data in three dimensions. Dr. Ollivier-Gooch and his group have written and maintain a software library for unstructured mesh generation. This software has been freely available for non-profit use on the WWW since January 1998, and is now in its tenth version. The software has been downloaded by over 6000 users in 62 countries. Applications vary from fluid and solid mechanics to cancer research and microbiology to simulation of star and planet formation.
