ESI Group Releases VA One 2007

By DE Editors

ESI Group (Paris, France) released VA One 2007 in September, and the news is just reaching the states now. VA One, analysis software for simulating the response of vibro-acoustic (VA) systems across the entire frequency range, enables optimal noise and vibration performance to be accounted for at the design stage, and ensures that noise and vibration specifications can be met without adding extra cost and weight.

VA One seamlessly integrates AutoSEA2, an industry-standard software for mid- and high-frequency noise and vibration analysis, and Rayon, a proven solver for low frequency vibro-acoustic analysis. In addition, VA One contains patented technology for rigorously coupling the finite element method (FEM), the boundary element method (BEM), and a statistical energy analysis (SEA) into one. VA One covers the complete spectrum of vibro-acoustic analysis in one easy-to-use environment,  states the press release.

The VA One 2007 release contains 35 enhancements including faster solution times for SEA and BEM models, support for the Windows Vista and Linux operating systems, and new functionality for creating fast and accurate models of grommets, leaks,  apertures, and grillages.
