ANSYS, INC. AND MATEREALITY, L.L.C. ANNOUNCE INTEROPERABILITY

Collaboration Exports Material Data from Matereality^® into ANSYS^® Workbench™

Southpointe, PA: January 17, 2006

ANSYS, Inc. (NASDAQ: ANSS), a global innovator of simulation software and technologies designed to optimize product development processes, today announced a collaboration with Matereality, L.L.C. that has produced an interface to smoothly export material data inputs from Matereality^® into ANSYS^® WorkbenchTM. As a result, ANSYS Workbench users can access a wealth of databases that contain material property data, furthering engineers’ ability to analyze designs directly on the desktop.

Matereality is a Web-based data management technology that contains thousands of datasets including stress-strain data; rate-dependent properties; hyperelastic properties; thermal properties; and creep, viscoelastic, and fatigue data on plastics, metals, rubber, foam and composites - data that is particularly relevant to the ANSYS user community and often not available publicly. The most extensive source of such data, Matereality also provides access to plastics material supplier databases, the MIL5 Handbook Database (used extensively by the aerospace and defense industries) and the NIST Lead-Free Solder Database (pertinent to the electronics industry).

Using Matereality’s MIRO CAE Wizard, ANSYS Workbench users can quickly search their personal databases, as well as important industry public and private data collections, for ANSYS-relevant data. They can evaluate the data for pertinence and export it digitally into ANSYS Workbench. Matereality is globally deployed and available to registered users anywhere, anytime.

"This technology interface will greatly expand the accuracy of simulations that ANSYS users can perform by giving them access to relevant material property data. The high-end capabilities of ANSYS in multi-physics, crash, fatigue, long-term behavior (creep), viscoelastic behavior and computational fluid dynamics can be more fully utilized with the easy availability of nonlinear material properties. ANSYS and Matereality will continue to build closer integration to extract wider varieties of ANSYS-relevant material data for future ANSYS material models," said Mike Wheeler, vice president and general manager at ANSYS.

Matereality does not have to be populated from scratch. It is scaleable to enterprise-level and has been designed to fit into and contribute to the collaborative world of product design, without each group having to redesign their own material data management systems. Providing a single source of data access ensures that all involved in a collaborative project use the same data fits and views for a specific material, rather than apply their own data fit calculations from input data from different databases, text books, testing services, etc.

"While serving an important role as a materials data resource, Matereality also allows ANSYS users to maintain their own personal material databases and have global, secure access and control over their data. In this system, users can hide, publish or selectively share data in keeping with their business needs, building collections that form an enduring part of the knowledge base of the enterprise", said Renu Gandhi, VP Business Development at Matereality. "As future ANSYS material models are developed, clients' material data within Matereality would always be ready for deployment using the relevant updates developed through the collaboration."
