IBM and Dassault Systèmes Announce Availability of 64-bit Applications for AIX

New functionality supports large assembly mock-up and analysis

Paris, France – October 13, 2004 – Dassault Systèmes (Nasdaq: DASTY; Euronext Paris: #13065, DSY.PA) and IBM today announced the first release of its 64-bit enabled Product Lifecycle Management (PLM) applications for the IBM AIX 5L operating system.

The applications are designed to provide 64-bit architecture capabilities for AIX Version 5 Release 14 (V5R14), which enables customers using ENOVIA DMU applications to perform digital mock-ups of full product configurations with a high level of detail and enables customers using CATIA V5 Structural Analysis to perform rapid finite element analysis on large assemblies.

Powered by IBM eServer pSeries systems, the 64-bit capability brings significant performance enhancement to users of CATIA Structural Analysis, ENOVIA DMU Navigator, ENOVIA Real Time Rendering and ENOVIA DMU Space Analysis for AIX 5.1 MIL 4.

Initial benchmarks indicate that for memory-intensive operations such as structural analysis of large models, overall performance is up to three times faster than the 32-bit version of the same application. In addition, the 64-bit capability enables users to analyse models three to four times larger.

“This achievement is a great illustration of how IBM advanced technology combined with leading-edge software developed by Dassault Systèmes contributes to protecting PLM customers’ investments,” said Per Larsen, vice president of IBM eServer pSeries Marketing, Systems and Technology Group.

"Customers already on IBM pSeries platforms will immediately benefit from this new version of CATIA and ENOVIA V5 with no additional investment,” said Florence Hu-Aubigny, director, research and development, open architecture, Dassault Systèmes. "For those who need to perform finite element analysis or design reviews on large assemblies, the availability of a 64-bit version of CATIA and ENOVIA V5 will streamline this process, improving their engineering efficiency."
