Description

ESI VA ONE 2019

ESI Group is pleased to announce VA One 2019 that offers a range of enhancements that will enable users to address common modelling applications in the automotive, aerospace, marine and industry sectors even more easily.

VA One 2019 highlights include:

- Ray Tracing Improvements as High-Order diffraction model and a tool to help user define best Ray Tracing parameters to optimize performance
FE Solver Improvements:
- Use of internal ESI FE solver based on VPS (Virtual Performance Solution) replacing COSMIC NASTRAN.
- FE Structural and FE Acoustic modal solves can now use VPS solver.
- Periodic Module now uses this solver and supports orthotropic/isotropic materials and uniform and composite cross-sections.

- Compact Acoustic Source (CAS) previously available as a Ray Tracing source can now also be used as a BEM source.
- DFAT Module now includes Optimization options to define best-fit sources from target levels and correlation at control microphones.
- Improved SEA line junction formulation and merge nodes improvement for SEA model building ease of use.

VA One is the only environment you need for vibro-acoustic simulation and design. Whether you’re simulating the acoustic transmission loss of an automotive firewall or creating a system level model of the vibro-acoustic response of a complete aircraft, VA One has all the methods you need to simulate vibro-acoustics across the entire frequency spectrum. Based on the industry standard software for mid and high frequency noise and vibration design AutoSEA2, and extended to encompass mid and low frequency methods (making use of the RAYON solver), VA One is the only simulation code on the market that contains the complete spectrum of vibro-acoustic analysis methods in a common environment. VA One also sets new standards in ease of use; VA One is a standalone Windows desktop application with a modern user interface that is quick, intuitive and very easy to use. With VA One you get results faster. Spend your time solving noise and vibration problems rather than trying to learn how to use complex CAD/CAE systems or relearning the user interfaces of a large number of disparate analysis codes. With VA One you get all the functionality you need for vibro-acoustics in onecommon environment.

The core functionality of VA One is split into five main modules: the SEA Module, Structural FE Module, Acoustic FE Module, Acoustic BEM Module and Hybrid Module. Adding a new module is simple and straightforward and gives you access to the methods you need to model the response of a vibro-acoustic system in a given frequency range. In addition, a large number of extension modules and scripts are available to help you customize VA One to meet specific requirements. These extension modules provide everything from customized model templates for specific applications to complete developer kits for writing custom scripts and GUIs within the VA One environment. VA One has the flexibility to meet your analysis needs.
