چکیده
Eines der Hauptziele des Applied Research Branch in der Numerical Aerodynamic Simulation (NAS) Systems Division am NASA Ames Research Center ist die beschleunigte Einfiihrung von parallelen Hochleistungsrechnern in ein produktionsorientiertes Rechenzentrum. In dieser Arbeit werden die Zielrichtungen des NAS Projekts in Bezug auf Parallelrechner dargestellt. Weiterhin werden die Erfahrungen mit experimentellen Parallelrechnern im NAS Applied Research Branch zusammengefasst. 1m Einzelnen wird iiber Ergebnisse mit Anwendungen in der Stromungsmechanik auf der Connection Machine CM-2 und dem Intel iPSC/860 berichtet. Ergebnisse von Berechnungen mit unstrukturierten Gittern und mit Teilchensimulationen werden dargestellt. Angesichts der Erfahrungen bei NASA wird die zunkiinftige Entwicklung von Parallelrechnern fiir die Anwendungen in der Stromungsl1lechanik diskutiert.

Experience with Parallel Computers at NASA Ames
Beginning in 1988, the Numerical Aerodynamic Simulation (NAS) organization at NASA Ames Research Center has studied the usability of highly parallel computers on computational uid dynamics and other aerophysics applications. Presently this organization operates a CM-2 with 32,768 nodes and an Intel iPSC/860 with 128 nodes. This note gives an overview of the experience in using these systems, hi...
متن کاملComputational Fluid Dynamics/Computational Structural Dynamics Interaction Methodology for Aircraft Wings
With advanced subsonic transports and military aircraft operating in the transonic regime, it is becoming important to determine the effects of the coupling between aerodynamic loads and elastic forces. Because aeroelastic effects can signi cantly impact the design of these aircraft, there is a strong need in the aerospace industry to predict these interactions computationally.Such an analysis...
