- ESI Group launches MARI Consortium for VA One Modelling Guidelines
London - 01/03/07,
Paris (France), 1st March 2007 – ESI Group has announced the launch of the European Marine, Aero, Rail and Industrial structures (MARI) Consortium, which will establish VA One Modelling Guidelines. Participants of the MARI Consortium include established industry leaders such as Alstom, BAE Systems, Bombardier Transportation, QinetiQ, Volvo Group and VTT.
The MARI Consortium was officially launched with a meeting held in Paris (France) in September 2006, and will continue convening until June 2008. The inaugural meeting provided a forum where each of the members shared details of target applications and objectives. Several intermediate sessions will follow, allowing participants to share knowledge and experience gained from executing the modelling tasks and report the progress made towards the mutually agreed objectives.
As a consortium member, each participant is provided with comprehensive training on an individual basis. ESI Group supervises and supports the project to ensure that efforts are focused on the primary objectives of creating effective modelling guidelines and defining productivity enhancements that will facilitate cost- and time-effective coupled FEA/SEA model creation for mid-frequency applications.
“The MARI Consortium is a great opportunity for each member to share experience in using VA One to model complex industrial structures for structure-borne noise prediction. The expertise gained from such activity and the interaction between members will help define commonly accepted modelling guidelines and provide ESI Group with valuable information to improve VA One´s model-building capabilities and automation. The MARI Consortium is another example of ESI Group´s commitment to providing Vibro-Acoustic industrial solutions across the full frequency range,” declares Denis Blanchet, in charge of ESI Group VA Product.
VA One is the world’s first – and still the only – fully integrated environment for vibro-acoustic simulation across the entire frequency spectrum. Based on AutoSEA2, the industry-standard software for mid- and high-frequency noise and vibration design, and extended to encompass mid- and low-frequency methods, VA One is the only simulation code on the market that contains a complete set of coupled vibro-acoustic analysis methods covering full-frequency spectrum.
What makes VA One unique is its ability to integrate rigorously within one single environment the Finite Element Method (FEM), the Boundary Element Method (BEM), and the Statistical Energy Analysis (SEA) method. The underlying coupling theory contained in VA One allows the user to deploy these different methodologies transparently, making VA One a powerful innovative solution for structure-borne noise analysis. This opens up brand-new application domains to the vibro-acoustic simulation world. It is now possible to build a single model with different modelling methods, couple them together and directly compute the vibro-acoustic response of a system.
A first successful Structure Borne Noise Consortium, which looked at how to implement the unique technology breakthrough that rigorously couples FEM and SEA into an easy-to-use software suite, gave birth to VA One. The consortium members evaluated for themselves the ease of use and the quality of the results by applying this new technology to their own industrial applications.
A follow-on consortium focusing on methodology has just been initiated. The objectives of the MARI Consortium are to define modelling guidelines and investigate aspects related to the automation of the model-building process for the creation of coupled Finite Element Analysis / Statistical Energy Analysis (FEA /SEA) models within the VA One environment. These objectives are set in the context of a technology transfer between ESI Group and the participants.
ESI Group’s vibro-acoustics solutions include: VA One, the first integrated software offering full-frequency spectrum analysis capabilities; AutoSEA2, the industry standard for real-time broadband noise and vibration prediction analysis and design software; RAYON, the low-frequency solution for characterisation of complex noise sources and prediction of vibro-acoustic performance including trimmed structures; RAYON-VTM (Vehicle Trim Modeler), an automation module used for low-frequency full-vehicle sound-package design; NOVA, a software package dedicated to the design of multi-layered acoustic components; and FOAM-X, a data acquisition and post-processing software program for identifying the acoustic properties of poro-elastic materials from impedance tube measurements.
About ESI Group
ESI Group is a pioneer and world-leading supplier of digital simulation software for prototyping and manufacturing processes that take into account the physics of materials. ESI Group has developed an entire suite of coherent, industry-oriented applications to simulate a product’s behaviour realistically during testing, to fine-tune the manufacturing processes in accordance with the desired product performance, and to evaluate the environment’s impact on product usage.
ESI Group’s products, which have a proven track record in manufacturing and have been combined in multi-trade value chains, represent a unique collaborative, virtual engineering solution, known as the Virtual Try-Out Space (VTOS), enabling virtual prototypes to be improved in a continuous manner. By drastically reducing costs and development lead times, VTOS solutions offer major competitive advantages and make it possible to eliminate gradually the need for physical prototypes. This integrated protocol allows all the company’s solutions to work with each other and with applications developed by independent software vendors. By significantly reducing costs and development lead times and enabling product/process synergies, VTOS solutions progressively eliminate the need for physical prototypes during product development, thus offering major competitive advantages.
ESI Group is listed on the Eurolist compartment C of Euronext Paris, and generated sales of €62.2m in 2005. The company employs over 500 high-level specialists worldwide, and covers more than 30 countries.
