Dassault Systèmes Announces New Release for Unified Finite Element Analysis from SIMULIA

Version 6.7 of Abaqus FEA Software Delivers Enhanced Performance, Innovative Functionality, and Expanded Application Coverage

Paris, France, and Providence, R.I., USA, May 15, 2007 - Dassault Systèmes (DS) (Nasdaq: DASTY; Euronext Paris: #13065, DSY.PA), a world leader in 3D and Product Lifecycle Management (PLM) solutions, announces the release of Abaqus Version 6.7, its technology-leading finite element analysis (FEA) software suite.

Abaqus Version 6.7 introduces a new architecture for high-performance linear dynamics, advanced capabilities for composites simulation and nonlinear materials modeling, a new intuitive and highly customizable user interface for accelerated model building and results visualization, and two new interfaces for bi-directional CAD associativity.

“SIMULIA is delivering several important enhancements to their Abaqus FEA software that we expect will greatly improve overall productivity at Scania," stated Martin Edberg, head of chassis simulations, Scania CV AB. "We are particularly impressed with the new high-performance linear dynamics functionality in Abaqus Version 6.7.”

The new linear dynamics architecture in Abaqus is fully integrated with existing nonlinear capabilities, enabling engineers to share model data and results seamlessly across workgroups. With this release, SIMULIA is providing the industry’s only unified simulation environment for general purpose structural integrity, powertrain durability, noise and vibration behavior, crashworthiness, occupant safety, and tire-roadway interaction. In addition, the software’s distributed memory parallel direct solver technology leverages the latest advances in high-performance computing to deliver significant performance improvements in clustered environments.

“We have developed a unique collaborative relationship with our customers that provides us with a clear view on which technical developments are most valuable to their businesses,” said Bruce Engelmann, CTO for SIMULIA. “The new materials capabilities in Abaqus Version 6.7 were created in response to environmentally driven industry issues and are helping electronics manufacturers adopt lead-free solder and enabling aerospace manufactures to drive fuel efficiency through application of complex composite materials.”

“The new CAD Associative Interface for Abaqus/CAE allows engineers to be more productive while iterating from CAD to FEA,” said Jerome Montgomery of Siemens Power Generation. “Loads and boundary conditions are retained between design changes, and the updates are handled efficiently through an intelligent mechanism that is a real time-saver.”

“Abaqus usage and adoption continues to grow rapidly as companies evolve their methods to be more sophisticated with the goal of improved fidelity to physical behavior,” stated Steve Crowley, director of product management at SIMULIA. “Abaqus 6.7 is the most scalable and powerful finite element analysis solution available on the market today.  We expect these enhancements to dramatically improve our customers’ business processes.”

With more than 100 major improvements, Abaqus Version 6.7 from SIMULIA continues to set the industry standard for realistic simulation through its technical excellence and product quality.
