Dassault Systèmes Announces New Capability for Analyzing Fluid-Structure Interaction with ABAQUS and STAR-CD

SIMULIA Collaborates with CD-adapco to Deliver State-of-the-Art Multiphysics Technology

Paris, France, and Providence, R.I. USA, February 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 availability of a powerful coupled-analysis capability for fluid-structure interaction (FSI) utilizing ABAQUS, the technology-leading finite element analysis (FEA) software from their SIMULIA brand, and STAR-CD, a market-leading computational fluid dynamics (CFD) software from CD-adapco.

The new FSI solution builds on the SIMULIA strategy of delivering an open platform for multiphysics simulation. The bi-directional coupling leverages a strong partnership with CD-adapco and the independent, open solution for the coupling—MpCCI software from Fraunhofer SCAI—to enable ABAQUS and STAR-CD to work together to solve a wide range of important FSI problems.

"This coupled solution provides the most powerful FSI technology available on the market,” states Dennis Nagy, VP of marketing and business development at CD-adapco. “Companies using our coupled solution will dramatically improve collaboration between fluid dynamics engineers and structural engineers. This will enable them to gain a greater understanding of system behavior and a competitive edge in delivering innovative inventions and products to market.”

"Multiphysics simulation such as FSI is increasingly important," says Ken Short, VP of strategy and marketing at SIMULIA. "It allows engineers to replicate and predict realistic physical behavior of complex systems where the interactions of fluid and structural responses are significant. Our customers will benefit tremendously from our open platform approach which enables them to easily integrate, fully supported best-in-class technology."

The new offering allows manufacturers and researchers in automotive, aerospace, off-shore, biomedical, consumer, and process industries to study the influence of fluid flow-induced forces and heat transfer on structural integrity as well as the impact of nonlinear material response on fluid flow behavior. This allows them to evaluate a broad range of conditions, such as flow-induced vibrations in structures, in-vivo vascular flows, valve dynamics. and fluid-structure applications in consumer goods and packaging.
