ESI VA One Product from ESI Group intended for design and analysis in the field of vibroacastics
The program allows you to take into account the optimal characteristics of noise and vibrations at the design stage and ensure the implementation of vibroacoustic requirements without additional costs and increase weight.

Innovative integration of analysis by finite elements (FEA) and analysis by the statistical method (SEA) in the same model allows the user to solve problems as successfully as with a separate application of SEA and FEA methods
VA One includes, of course, AUTOSEA2, a standard vibro-acoustic analysis program for medium and high frequencies, and Rayon, solver, which has already proven its effectiveness in vibroacoustic analysis for the low frequency area. In addition, VA One uses a patented technology that guarantees a clear interaction of the finite element method (FEM) with the method of border elements (BEM) and with the method of statistical analysis (SEA) within a single analysis. VA One is the only solution that covers the full range of vibroacoustic analysis in a friendly environment.
