James E. Cashman III, President and Chief Executive Officer of ANSYS, Inc., will join host Bruce Aust, Executive Vice President of NASDAQ, to preside over the Market Open, Thursday, January 13, 2005 at 9:30 a.m. EST. Of the currently listed NASDAQ companies, ANSYS is the only Pittsburgh-based company to participate in this event twice. Additionally, ANSYS rang the Opening Bell in January 2004. The invitation to ring the Opening Bell is further validation of ANSYS' strong performance and signals the growing importance of computer-aided simulation for businesses -- ANSYS' sole focus for over three decades. To continue its mission to broaden the product suite, ANSYS recently acquired Century Dynamics, Inc. a leading provider of sophisticated yet easy-to-use simulation software for solving linear, nonlinear, explicit and multi-body hydro-dynamics problems.
