ESI VA One product from ESI GROUP designed for the design and analysis of vibro-acoustics.

Lighter, faster and quieter
Government legislation, competitive pressure and tight development schedules mean you can't afford to wait until your product is built to find unexpected noise and vibration problems. With ESI's vibroacoustic simulation software you no longer have to. Account for noise and vibration harshness right at the design stage - no more costly delays or panic driven test-based solutions. With the acoustic modeling software, You can diagnose potential noise and vibration problems up front in your development process. Manage risk by identifying possible problem areas that may need more detailed modeling or test based development, while you still have time to make an impact on the product!

The full spectrum of solutions ...
Whether you are creating SEA models of initial concept designs or fully detailed Finite Element and Boundary Element models of final prototypes, ESI has all the simulation methods you need. Design for noise and vibration performance across the full frequency spectrum, leveraging decades of company research.

Design evaluation
With our unique way of coupling statistical and deterministic modeling methods in a hybrid way, you have the flexibility to make models as detailed or as simple as you need. Create system level noise and vibration models in a matter of hours and get solutions in seconds, even on a laptop. Our VA software helps you rank sources and identify dominant transmission paths quickly. Get answers to key design questions in real-time, not tomorrow or next week.
