ESI Announces VA One V2009.0Latest release of noise and vibration software includes advanced models of foam and fibers

Paris, France - February 16, 2010 - ESI Group (ISIN FR0004110310), pioneer and world-leading supplier of digital simulation software for prototyping and manufacturing processes, announced today the release of VA One 2009. VA One is a complete solution for simulating noise and vibration across the full frequency range and seamlessly combines Finite Elements, Boundary Elements, and Statistical Energy Analysis (SEA) in a single model. This new release significantly enhances the functionality for modeling foams and fibers in VA One.

Poroelastic MaterialsPoroelastic materials such as foams and fibers are an important part of the design of quiet products with superior noise and vibration performance. VA One is the only code on the market that includes methods for optimizing poroelastic materials across the full frequency spectrum. The VA One 2009 release includes an advanced ''foam finite element'' solver that is ideal for modeling the low frequency response of foams and fibers. Originally developed as part of a long term research project between ESI Group and several leading universities, this solver is now fully integrated within the VA One environment.

''Modeling the vibro-acoustic response of poroelastic materials is one of our core areas of research'', said Pr. Noureddine Atalla, Acoustic Department at the University of Sherbrooke. ''Our ongoing collaboration with ESI Group on the research, development and implementation of these methods has proven to be fruitful as shown in VA One latest release''.

Productivity enhancementsThe VA One 2009 release also includes a number of unique enhancements for speeding up the creation of poroelastic models, including automatic creation of meshes from extrusion of CAD surfaces and the calculation of equivalent mid and high frequency noise control treatments from CAD.

''We are pleased to announce the release of VA One 2009'' said Dr. Phil Shorter, Director of Vibro-Acoustic Product Operations, ESI Group. ''This release is the result of a long term collaboration with our research partners and provides our customers with state-of-the-art methods for modeling poroelastic materials ''.
