PREFACE ParCFD 2001, the thirteenth international conference on Parallel Computational Fluid Dynamics took place in Egmond aan Zee, the Netherlands, from May 21-23, 2001. The specialized, high-level ParCFD conferences are organized yearly on traveling locations all over the world. A strong back-up is given by the central organization located in the USA (www.parcfd.org). These proceedings of ParCFD 2001 represent 70% of the oral lectures presented at the meeting. All published papers were subjected to a refereeing process, which resulted in a uniformly high quality. The papers cover not only the traditional areas of the ParCFD conferences, e.g. numerical schemes and algorithms, tools and environments, interdisciplinary topics, industrial applications, but, following local interests, also environmental and medical issues. These proceedings present an up-to-date overview of the state of the art in parallel computational fluid dynamics. We believe that on basis of these proceedings we may draw the conclusion that parallel CFD is on its way to become a basic engineering tool in design, engineering analysis and prediction. As such, we are facing a next step in the development of parallel CFD and we hope that the papers in this book will contribute to the inspiration needed for enabling this development. P. Wilders This Page Intentionally Left Blank vii ACKNOWLEDGEMENTS The local organizing committee of ParCFD 2001 received a lot of support, both financial and organizational. In particular, we want to thank the international scientific committee for its help in the refereeing process and for proposing excellent invited speakers. This enabled us to organize a high-level conference. Financial support to ParCFD 2001 was obtained from: (cid:12)9 Delft University of Technology (cid:12)9 J.M. Burgers Centre (cid:12)9 Royal Dutch Academy of Sciences (cid:12)9 AMIF/ESF (cid:12)9 Eccomas (cid:12)9 Delft Hydraulics (cid:12)9 National Aerospace Laboratory NLR (cid:12)9 Platform computing (cid:12)9 Compaq (cid:12)9 Cray Netherlands The financial support enabled us not only to organize an excellent scientific and social program, but also to set up an attractive junior researchers program and to grant some researchers from Russia. The working group on "Affordable Computing" of the network of excellence MACSINET helped us to organize a very successful industrial day. Finally, the main organizer, P. Wilders, wants to thank staff and colleagues of Delft University for their strong support from the early beginnings. The local organizing committee, A.W. Heemink (Delft University of Technology) M.S.
