ANSYS Earns Desktop Engineering Readers' Choice Award

SOUTHPOINTE, Pa., Jan. 26, 2005 -- ANSYS, Inc. , a global innovator of simulation software and technologies designed to optimize product development processes, today announced that its ANSYS(R) CFX-5.7 product received the Desktop Engineering's Readers' Choice Award for October 2004.

Desktop Engineering selected the winner by determining the number of reader service inquires received in response to the product announcements published in the July 2004 issue of Desktop Engineering. The ANSYS CFX-5.7 announcement received the most inquiries.

As the latest release in the powerful CFX-5 series, ANSYS CFX-5.7 offers further integration into the ANSYS family of analysis technologies, providing better performance, enhanced interoperability with other ANSYS tools and more accessible complex physics and multiphase simulations. In addition, CFX-5.7 introduces true fluid-structure interaction (FSI) capability. A simple, one- way transfer of data from a CFX(R) solution to ANSYS enables CFX-5.7 to pass information between a fluid and structural simulation. This capability, as part of ANSYS 9.0, will evolve to full bi-directional dynamic coupling within the ANSYS Workbench environment.

"It is encouraging to know that Desktop Engineering readers, many of whom are ANSYS customers, find value in our product announcements," said Jim Cashman, president and CEO at ANSYS, Inc. "This recognition is a validation that we have communicated the ANSYS CFX-5.7 message -- a robust CFD tool with tighter integration with ANSYS tools -- to the right audience."
