Paris, France-- ESI Group, which develops digital simulation software for prototyping and manufacturing processes, has released VA One 2009. The company says the VA One software " is a complete solution for simulating noise and vibration across the full frequency range." It combines Finite Elements, Boundary Elements, and Statistical Energy Analysis (SEA) in a single model.
This new release is claimed to significantly enhance the software's functionality for modelling foams and fibres.
Poroelastic materials such as foams and fibres are an important part of the design of quiet products with superior noise and vibration performance, and French group ESI says VA One is the "only code on the market that includes methods for optimising 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 fibres. 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 Professor Noureddine Atalla, Acoustic Department at the University of Sherbrooke, in ESI's statement. "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".
