Benefits of Engineering Simulation to the Oil and Gas and Renewable Industries to be Highlighted

Canonsburg, PA. – October 13, 2008 – ANSYS, Inc. (NASDAQ: ANSS), a global innovator of simulation software and technologies designed to optimize product development processes, today announced the preliminary agenda for its Engineering Simulation Energy Conference (ESEC). Keynote and technical presentations will offer leading-edge applications focused on solving complex, real-world problems. Providing a unique forum for the application of engineering simulation technology specific to the energy industry, ESEC is scheduled for November 11 and 12, 2008, in Houston, Texas, U.S.A. The event is the successor to the International Oil and Gas CFD conference (IOCC) held in London in 2006. Due to the IOCC’s success, ESEC is planned to be far broader, covering the whole of the energy industry — oil and gas, production and processing, and renewable energy including wind, wave and solar — and to include a far wider technical focus, with applications and technologies representing the entire multiphysics spectrum of engineering simulation.

Today, the challenges faced in extracting oil and gas are growing, since conventional reserves have been tapped and the industry is increasingly seeking petroleum and natural gas sources from more extreme locations, such as ultra-deep water or tar sands. In exploring challenges related to the scale-up of renewables, such as solar, wind and tidal power, the issues include increasing development costs or project planning. And above all else, the need to protect the environment, to minimize emissions and to lower the carbon footprint of any and all energy sources is paramount. Collectively, these trends signify that the benefits of applying engineering simulation to meet the diverse challenges in the energy sector have never been greater.

The ESEC program for day one features speakers and thought-leaders from pioneering organizations in the global energy industry. Among the keynote presenters are Mark Peters of Gulf Publishing, which sponsors events and publishes information dedicated to the energy sector (including Hydrocarbon Processing), on the state of the industry, trends and opportunities; Washington Geraldelli of major Brazilian oil producer PETROBRAS (CENPES) highlighting refining and processing; Roberto Ruiz of the process burners group at leading industrial combustion technology company John Zink speaking on pollution control and combustion systems; Grant Bromhal from NETL in the U.S. Department of Energy speaking on carbon sequestration; Scott Parent at GE Gasification, one of the world's leading providers of both gasification and power generation technologies, discussing renewable energy; Roger Basu from marine standards developer American Bureau of Shipping on engineering challenges in sea keeping; and Jim Cashman, president and CEO of ANSYS, Inc. presenting on innovation in energy and the role of engineering simulation.

Day two features users of ANSYS software presenting leading-edge applications from real-world case studies that showcase ways to apply engineering simulation to maximum effect. There are three technical tracks: upstream and production, refining and processing, and renewables and environment. Multiple discussion forums will provide attendees with the opportunity to drill further into each of six pivotal subject areas (multiphysics, LNG – gasification, high-performance computing, flow assurance, equipment and reactor design, and offshore structures), share and debate ideas, and learn how to maximize the use of engineering simulation in this rapidly developing industry sector.

A technology pavilion at ESEC will feature a wide range of complementary hardware and software suppliers. There is also an exciting social program planned for delegates and partners.

ESEC will uniquely bring together leading technology solutions providers, industry experts and thought-leaders in the energy industry under one roof to hear how computational technology and engineering simulation software can accurately and efficiently test and predict operational efficacy and environmental impact to reduce design and development times, minimize costs, and ensure regulatory compliance.
