Dassault Systèmes Announces New

SIMULIA Multiphysics Platform

Direct Coupling Interface and New Fluid-Structure Interaction

Technology Expands Realistic Simulation Offerings

Paris, France, and Providence, R.I., USA, May 21, 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 new SIMULIA direct coupling interface that allows third-party physics codes developed by partners or customers to communicate directly with its Abaqus FEA software for high-performance multiphysics simulation.

 

The new interface is a key step in the delivery of the SIMULIA multiphysics platform to support the integration of diverse applications, data, and users from multiple domains for product development and scientific research. Industry partners and customers are leveraging the new interface to directly couple their software with the Abaqus FEA suite to achieve simulation results that are closer to real-world behavior.

 

“We have worked very closely with the SIMULIA team in the development and testing of their new interface,” said Dr. Farzin Shakib, CEO of ACUSIM, a developer of commercial CFD software. “I am confident that our mutual customers will benefit greatly from the combination of best-in-class FEA and CFD tools working together to deliver a directly coupled multiphysics solution.”

 

The new SIMULIA direct coupling interface will complement existing Abaqus multiphysics capabilities such as coupled structural-acoustic, piezoelectric-mechanical, and electrical-thermal simulation. The SIMULIA multiphysics platform also supports third-party protocols including the Mesh-based parallel Code Coupling Interface (MpCCI) from Fraunhofer SCAI.

 

"Providing an open platform and complete multiphysics solutions are critical aspects of the overall SIMULIA strategy and represents a collaborative effort that has been under development for more than a year," stated Ken Short, vice president of strategy and marketing at SIMULIA. “With the SIMULIA platform and our extensive partner ecosystem we will provide our customers with the most comprehensive multiphysics solutions available."

 

In addition to the new direct coupling interface, SIMULIA is expanding its Abaqus Unified FEA multiphysics capabilities to include Fluid-Structure Interaction (FSI). This Abaqus FSI capability, which will be demonstrated at the 2007 Worldwide Abaqus User meeting May 22–24, will enable engineers and scientists to simultaneously calculate the behavior of fluids and structures in a single model.

 

“Applications such as airbag inflation, tire hydroplaning, wave loading on offshore structures, or cosmetics dispensing are ideally suited to this innovative approach,” said Bruce Engelmann, CTO at SIMULIA. “We’ve targeted some of the most important industrial applications where the dynamic behavior of fluids and structures strongly influence design decisions. Our new capability will be a significant extension of our fully scalable Abaqus Unified FEA suite, providing customers with the right solution for the problem at hand.”

“We support SIMULIA and their vision for offering comprehensive multiphysics solutions,” commented Steve MacDonald, president & CEO CD-adapco, a leading provider of CFD solutions. “Combined with our own expert system and the existing MpCCI-enabled fluid structure interaction coupling solution of our STAR-CD product with Abaqus, this new direct coupling will offer mutual customers the utmost flexibility in performing multiphysics analyses.’’
