Dynasim Delivers Next Generation Modelica-based Multi-Engineering Modeling and Simulation Solution

Bielefeld, Germany, March 3, 2008 - Dassault Systèmes (DS) (Nasdaq: DASTY; Euronext Paris: #13065, DSY.PA), a world leader in 3D and Product Lifecycle Management (PLM) solutions, today announced that Dynasim, the leader in Modelica-based multi-domain systems modeling and simulation solutions, released Dymola 7.0, the latest version of its comprehensive product suite. Highlights of this new version include the support of Modelica 3.0, the latest version of the powerful object-oriented modeling language for complex physical systems, as well as support of the new Modelica Standard Library 3.0.

“I am delighted that Dynasim is already supporting Modelica 3.0 with its new Dymola 7.0 products”, said Prof. Dr.-Ing. Martin Otter, German Aerospace Center (DLR), Institute of Robotics and Mechatronics, and chairman of the Modelica Association. “Modelica 3.0 was released in September 2007, introducing significant evolutions in the language specifications to better address industrial needs for the development and maintenance of larger and detailed, highly realistic models while enabling high-performing error diagnostics. The Modelica community is expanding and investing heavily to develop new Modelica libraries. During the three-year ITEA2 EUROSYSLIB project, initiated by DS and DLR, and involving 20 partners, more than 100 man-years will be spent on developing model libraries in Modelica.”

The Dymola 7.0 release features key enhancements that take large multi-domain modeling and simulation to a new level of performance and accuracy:

• Improved model lifecycle management capabilities with the support of the Modelica 3.0 language. Modeling through component reuse is drastically enhanced and simplified thanks to new local balancing between variables and equations. In addition, the requirement for plug compatibility enables customers to experiment with different model variants and levels of details reliably.

• New and extended model libraries with support of the new Modelica Standard Library 3.0 including electrical, mechanical, thermal and control components and model libraries from partners for automotive powertrain, flexible bodies, vehicle dynamics, electric drives and air-conditioning systems.

“Dymola 7.0 is a significant step in providing a scalable modeling and simulation solution for complex products involving many engineering disciplines,” said Dr Hilding Elmqvist, founder and CEO, Dynasim AB. “The combination of extensive, multi-discipline libraries based on the open Modelica language and the numerous improvements brought by Dymola 7.0 make Dymola a unique and unmatched solution. It meets new and increasing demands for model-based integrated product development, which will give users a competitive advantage by shortening time to market.”

As a cornerstone of DS’s systems strategy, Dymola technology will be at the heart of CATIA Systems V6 solutions.

The new Dymola 7.0 product suite is being presented at the Modelica Conference 2008 in Bielefeld, Germany, starting today. For more information, go to http://www.modelica.org/events/modelica2008
