Dassault Systèmes Announces New Release of Abaqus Unified Finite Element Analysis from SIMULIA

Abaqus Version 6.7 Extended Functionality Release Delivers Advanced Multiphysics, Productivity and Performance Enhancements

Paris, France, and Providence, R.I., USA, December 12, 2007 – Dassault Systèmes (DS) (Nasdaq: DASTY; Euronext Paris: #13065, DSY.PA), a world leader in 3D and Product Lifecycle Management (PLM) solutions, today announced the availability of Abaqus Version 6.7 Extended Functionality (EF), its technology-leading finite element analysis (FEA) software suite from SIMULIA.

The release builds on SIMULIA’s promise of delivering a broader set of solutions within an open, unified simulation environment. New capabilities in Abaqus Version 6.7-EF include native technology for multiphysics fluid-structure interaction (FSI), an associative geometry interface to SolidWorks, collaborative modeling capabilities, tools for managing material libraries, and visualization capabilities for solid composites, as well as dozens of additional customer-requested enhancements.

“This extended functionality release of Abaqus demonstrates our focus on advanced simulation technology and usability features that enable our customers to accelerate the evaluation of the real-world behavior of their products,” stated Steve Crowley, director of product management, SIMULIA. “The new multiphysics technology within Abaqus streamlines the process of evaluating the performance of structures interacting with fluids, such as tire hydroplaning or container drop, which is critical to improving product safety and quality.”

"The SolidWorks Associative Interface in Abaqus is a direct result of customer demand," stated Rainer Gawlick, vice president of worldwide marketing, SolidWorks. "This capability provides significant gains in efficiency and quality by enabling SolidWorks users to make immediate design performance decisions based on advanced analysis results from Abaqus."

Abaqus Version 6.7-EF New Features and Enhancements:

• Coupled Eulerian Lagrangian (CEL) analysis enables fluid structure interaction within Abaqus/Explicit. CEL also provides the ability to analyze the performance of solid materials undergoing extreme deformation.
• Abaqus/CAE FSI Interface simplifies the process of defining coupled fluid-structure interaction models with third-party computational fluid dynamics software.
• The SolidWorks Associative Interface provides geometry transfer and maintains the relationship between SolidWorks and Abaqus models.
• Collaborative modeling in Abaqus/CAE allows the import of models and objects from other Abaqus databases into the current analysis session, facilitating concurrent modeling between multiple engineers.
• The Material Library in Abaqus/CAE enables the efficient use and management of material properties from a variety of sources including proprietary corporate databases.  Additionally, new third-party plug-ins offered by Granta Design and Matereality provide access to a broad range of materials associated with industrial and military/aerospace databases, such as MMPDS-03.
• Contact enhancements for pre- and post-processing offer automatic contact detection support, geometry- and mesh-based searches, plus contact output.
• Improvements to the Distributed Memory Parallel solver support parallel element operations with steady-state transport, plus improved performance and scalability for analyses with a large number of processors.
• Permanent set with hyperelasticity in Abaqus/Standard and Abaqus/Explicit enables higher fidelity modeling of filled elastomers and thermoplastics such as those used in car door seals, mounts, and sports equipment.
• Composites solid modeling enables the direct assignment of material layers to solid elements and provides results visualization of solid composites.

Abaqus Version 6.7-EF offers a unified finite element solution that increases confidence in design decisions, reduces physical testing, and accelerates time-to-market.
