Applications of computational modeling in ballistics

The development of the technology of ballistics as applied to gun launched Army weapon systems is the main objective of research at the U.S. Army Ballistic Research Laboratory (BRL). The primary research programs at the BRL consist of three major ballistic disciplines: exterior, interior, and terminal. The work done at the BRL in these areas was traditionally highly dependent on experimental testing. A considerable emphasis was placed on the development of computational modeling to augment the experimental testing in the development cycle; however, the impact of the computational modeling to this date is modest. With the availability of supercomputer computational resources recently installed at the BRL, a new emphasis on the application of computational modeling to ballistics technology is taking place. The major application areas are outlined which are receiving considerable attention at the BRL at present and to indicate the modeling approaches involved. An attempt was made to give some information as to the degree of success achieved and indicate the areas of greatest need

Computer Methods in Applied Mechanics and Engineering 190 (2000) 263–277 1 Comments on CFD Code Performance on Scalable Architectures

We comment on the current performance of computational fluid dynamics codes on a variety of scalable computer architectures. The performance figures are derived from both the finite volume and finite element methodologies, and encompass shared, virtual shared, and distributed memory architectures, as exemplified by the SGI Origin series, CM5, and the CRAY T3D/E family, respectively. 1
