Dassault Systèmes and Fluent Establish CAA V5 Software Partnership

Fluent to provide fluid flow simulation within CATIA V5 environment

Seattle, USA and Paris, France – September 30, 2003 – Dassault Systèmes (NASDAQ: DASTY; Euronext Paris: #13065, DSY.PA) announced today a strategic partnership with Fluent, a world leader in Computational Fluid Dynamics (CFD) software. Fluent has joined Dassault Systèmes’ Software Community Program as a CAA V5 Software Partner and will develop, market, and sell CFD solutions based on the Dassault Systèmes Component Application Architecture (CAA V5). Through this partnership, Fluent will complement the existing V5 suite of Analysis solutions and provide V5 users with fluid flow simulation within the standard CATIA®V5 environment.

Dassault Systèmes V5 Product Lifecycle Management (PLM) Simulation solutions deliver a unique set of knowledge-based analysis tools, embedded within an intuitive and user-friendly collaborative environment that supports fast design-to-analysis iterations. Thanks to this partnership, key Fluent CFD technologies will be tightly integrated with the modeling power of CATIA V5 and will leverage the V5 PLM simulation backbone. Fluent extends Dassault Systèmes PLM Solutions capabilities to fluid dynamics and addresses the challenges facing Electrical & Electronics (E&E), aerospace and automotive customers. Initial product plans include Fluent/FloWizard for CATIA V5, a CAA V5 Based fluid flow simulation solution.

Users will then be able to fully prepare their CFD analysis model within the CATIA V5 environment. By maintaining associativity between the design and analysis models, Fluent’s CAA V5 Based products will reduce the time required for analysis of design iterations and allow CFD to be applied more readily to product optimization. The new Fluent/FloWizard for CATIA V5 software will use the industry standard FLUENT 6.x CFD solver thus providing unlimited access to the complete spectrum of Fluent technologies. It will allow designers to perform in process Thermal Flow simulation earlier in the product lifecycle and therefore support « Flow Critical » processes. The insight and efficiency that users will gain will result in higher quality designs and reduced time-to-market, ultimately lowering product development costs. The integration within CATIA Version 5 also ensures ease-of-use and therefore a fast learning curve for designers.

“Fluent is the recognized leader in CFD, with a strong commitment to successfully integrate CFD in the design process,” said Séverin Lanfranchi, director Research & Development, CATIA Simulation, Dassault Systèmes. “Users of Dassault Systèmes PLM solutions and of the Fluent/FloWizard for CATIA V5 product will benefit from combining the best-available PLM solution with the best-available technology for flow simulation. This will allow customers to streamline the analysis process and deploy CFD simulation more widely.”

“The integration of Fluent technology with the CATIA V5 environment is part of Fluent’s mission to help our customers successfully deploy CFD in their design process,” said Dr. Ferit Boysan, president of Fluent. “We are very pleased to work jointly with Dassault Systèmes in the CFD technology area and we look forward to providing enhanced value to our common customers.”
