ANSYS’ ICEM CFD Cart3D Software Available for Commercial Distribution

Canonsburg, PA – August 12, 2002 - ANSYS Inc. (NASDAQ: ANSS), a global innovator of simulation software and technologies designed to optimize product development processes, today announced that it has integrated NASA AMES’ Cart3D product, recently recognized as NASA’s “Best Software of the Year,” into its ICEM CFD product suite for commercial distribution. Cart3D is a high-fidelity, inviscid analysis package for external and internal flow simulations developed by NASA Ames Research Center and New York University for conceptual and preliminary aerodynamic design.

ANSYS has integrated Cart3D v1.1 as an addition to its ICEM CFD product suite, enabling the package to be licensed commercially as ICEM CFD Cart3D in five industries. In addition to its exclusive distributor status for NASA Ames’ Cart3D solution to the aerospace, automotive and turbo machinery industries, ANSYS also has distribution rights for the electronics/ electromagnetics and process industries. Moving forward, for non-government users, the Cart3D product only can be licensed through ANSYS or its authorized channel partners.

"Cart3D's novel algorithms and its state-of-the-art computational efficiency combine to provide designers with a new level of automation that reduces simulation time requirements by a factor of at least 250," said NASA Ames’ Michael Aftosmis, one of the co-developers of Cart3D. "This level of automation encourages designers to test more vehicle variations over a wider range of flight conditions than previously possible."

"We are honored to be selected as a NASA Ames partner," said Dr. Armin Wulf, ANSYS Vice President and General Manager. “NASA’s ‘Best Software of the Year’ award clearly validates the Cart3D technology as the most advanced design tool available to designers and engineers. We are encouraged to offer ICEM CFD Cart3D as a part of our product suite and deliver this technology to a broader user base.”

With the commercialization of Cart3D through ANSYS, users are able to receive dedicated support and training, as well as additional functionalities of the ICEM CFD product suite, such as a GUI for problem setup and post-processing, enhanced import of legacy geometry, direct import of CAD geometry, and the ability to automatically setup and run suites of simulations based on parametric changes to models.
