Dassault Systèmes Announces
Abaqus for CATIA V5 Version 2.5 from SIMULIA

Productivity and Ease-of-Use Enhancements Improve Realistic Product Behavior Simulation During the Design Phase

Paris, France, and Providence, R.I., USA, September 13, 2007 - Dassault Systèmes (DS) (Nasdaq: DASTY; Euronext Paris: #13065, DSY.PA), a world leader in 3D and Product Lifecycle Management (PLM) solutions, today announced that its SIMULIA brand for realistic simulation, has released Abaqus for CATIA Version 2.5, the technology-leading software for advanced finite element analysis (FEA) in the CATIA environment.
 
"Abaqus for CATIA allows our design engineers to immediately evaluate how new concepts and design changes affect product performance," states Michael Thienel, MANN+HUMMEL GMBH, Filter Elements Business Unit. "This approach not only accelerates our development time, but also improves knowledge of our design's physical behavior, giving us greater confidence in our product quality during the development stage."

“Abaqus for CATIA helps us to minimize the number of software interfaces that we use during the development of our exhaust turbocharger,” states Markus Staedeli, ABB Turbo Systems Ltd. “With Abaqus for CATIA we can work seamlessly with the same geometry model throughout our virtual development process. This integrated simulation workflow provides significant efficiency gains for our company.”

The latest release, available on the latest 64-bit computing architecture as well as 32-bit systems, provides tighter integration with CATIA through support of CATIA Knowledgeware, publications, and sensors, as well as ease-of-use enhancements such as automatic contact detection.

 “Abaqus for CATIA Version 2.5 addresses our customers’ requirements for tighter integration with CATIA and improved usability of advanced Abaqus features, such as contact and nonlinear analysis workflows,” states Steve Crowley, director of SIMULIA product management for Dassault Systèmes.  “This release is a key component of our strategy to deliver solutions that enable design engineers and expert analysts to collaborate efficiently throughout the product lifecycle by using approved methods, common FEA models, and synchronized data.”

The new product leverages CATIA’s Knowledgeware, which allows users to capture design knowledge and reuse it as best practices to ensure compliance with established standards. The new automatic contact detection feature simplifies the modeling process and reduces potential errors by providing a wizard-based interface that guides users through setup options and automatically detects all likely contact pairs.
