ESI Group announces the release of VA One 2016. VA One is full-frequency, single-environment simulation software available for solving a wide range of noise and vibration design challenges in automotive, aerospace, marine and industrial applications. VA One combines Finite Elements, Boundary Elements and Statistical Energy Analysis into one flexible modeling environment.
ESI VA One 2016 optimizes ongoing improvements in multi-core processing to provide significant improvements in overall model run time and overall performance speed, particularly in read, write, and solve steps. It also introduces capabilities for flexibly modeling complex loads and is able to address the growing challenge faced by the automotive and aerospace industries to accurately predict wind and other noises due to turbulent flow effects. Excessive wind noise, which is generated by vehicles moving at high speed, is more than simply an acoustic annoyance to end users: excessive wind noise negatively impacts phone calls and applications using voice recognition inside the vehicle. Reducing wind noise as much as possible is thus crucial to allow optimal performance of various in-car communications.
Key highlights of VA One 2016:
- Unique Enhancement Provides the Ability to Accurately Apply Complex Aero-Vibro-Acoustic (AVA) Loads to SEA (Statistical Energy Analysis) Models
- Enhanced Acoustic Predictive Capabilities for FE Models with Complex Flow
- Performance and Productivity Enhancements
VA One 2016 delivers an array of overall performance and speed improvements that specifically address the aerospace, automotive, marine and industrial markets. Improvements specifically address multi-core BEM (Boundary Element Method) calculations and customers in automotive and related industrial markets will benefit from the new BEM improvements in Radiated Noise Calculations for modeling exterior noise generated, for example, by vehicle powertrains, consumer electronics, and industrial generators. Speed increases up to a factor of fifty have been achieved in certain complex BEM multi-core calculations.
Aerospace and marine customers will benefit from improved SEA modelling of ribbed panels, such as used in lower hull sections for marine applications in the fuselages of aircraft.
