This book contains the main results of the German project POPINDA. It surveys the state of the art of industrial aerodynamic design simulations on parallel systems. POPINDA is an acronym for Portable Parallelization of Industrial Aerodynamic Applications. This project started in late 1993. The research and development work invested in POPINDA corresponds to about 12 scientists working full-time for the three and a half years of the project. POPINDA was funded by the German Federal Ministry for Education, Science, Research and Technology (BMBF). The central goals of POPINDA were to unify and parallelize the block-structured aerodynamic flow codes of the German aircraft industry and to develop new algorithmic approaches to improve the efficiency and robustness of these programs. The philosophy behind these goals is that challenging and important numerical appli cations such as the prediction of the 3D viscous flow around full aircraft in aerodynamic design can only be carried out successfully if the benefits of modern fast numerical solvers and parallel high performance computers are combined. This combination is a "conditio sine qua non" if more complex applications such as aerodynamic design optimization or fluid structure interaction problems have to be solved. When being solved in a standard industrial aerodynamic design process, such more complex applications even require a substantial further reduction of computing times. Parallel and vector computers on the one side and innovative numerical algorithms such as multigrid on the other have enabled impressive improvements in scientific computing in the last 15 years.

This volume contains the summarizing of the most important developments and results obtained in the project "Portable Parallelization of Industrial Aerodynamic Applications (POPINDA)" which was supported by the German Bundesministerium f?r Bildung, Wissenschaft, Forschung und Technologie (Federal Ministry of Education, Science, Research and Technology, BMBF) and carried out between summer 1993 and 1997. In this project four block-structured industrial aerodynamic application codes have been unified, standardized and parallelized in a portable way by the development of a high-level communications library. Large scale benchmarks demonstrate the obtained benefits. In addition to these topics this volume describes algorithmic adaptations to the needs of parallel computing and new algorithmic developments in order to accelerate the multigrid algorithms employed. A special focus is laid upon the development of appropriate methods for the support of adaptive grid structures on parallel computers.
