New Release of FLUENT for Catia v5 Enhances Productivity Through Integration and Automation CATIA-Integrated Computational Fluid Dynamics Analysis Offers Robust Tools and Minimizes Learning Curve for Use in All Phases of Design Process

SOUTHPOINTE, PA – April 11, 2007 – ANSYS, Inc. (NASDAQ: ANSS), a global innovator of simulation software and technologies designed to optimize product development processes, today announced the release of version 3.0 of FLUENT® for Dassault Systèmes’ CATIA® V5 software. This release provides workflow enhancements and new features that further improve the integration of Fluent’s computational fluid dynamics (CFD) technology in the CATIA V5 product lifecycle management (PLM) environment. FLUENT technologies are now part of the ANSYS CFD suite, from the company’s recent acquisition of Fluent Inc.

This new release was developed by Fluent as a member of Dassault Systèmes’ CAA V5 software community program. FLUENT for CATIA V5 delivers the ANSYS vision of Simulation Driven Product Development to customers working within the V5 PLM environment pioneered by Dassault Systèmes. Operating completely within the native CATIA V5 data structures, FLUENT for CATIA V5 provides a fully generative relationship between engineering organizations’ manufacturing-ready geometry models and the flow and heat transfer analysis model.

“FLUENT for CATIA V5 is a key component in bringing CFD analysis capabilities to the entire CAA V5 user community, from dedicated CFD analysts to product designers,” said Paul Bemis, vice president of product strategy at ANSYS, Inc. “The version 3.0 release closely follows December’s version 2, illustrating the ANSYS ongoing commitment to this technology with significant product enhancements and short release cycles. As a result, we continue to add new features to the software, and users can take advantage of the benefits almost immediately.”

Version 3.0 builds upon the functionality of previous releases, especially in the areas of workflow and automation. These improvements in the integration with CATIA V5 result in both a reduced learning curve and model setup time for the user. Version 3.0 builds in full support of CATIA V5 VB scripting and macros, enabling the customization of repetitive tasks that can lead to improved efficiency. Other enhancements include more streamlined update scenarios for large geometrical modifications, easier management of parallel processing, extended post-processing options, and additional user guidance and information during the case set-up process. These new or improved features further increase the tool’s productivity and extend the CATIA V5 PLM benefits to all FLUENT for CATIA V5 users.

Version 3.0 of FLUENT for CATIA V5 is available for immediate shipment. Product configuration and pricing information are available from ANSYS. Additional product details and demonstrations are available at www.fluentforcatia.com.
