ESI Group Announces VA One 2016
Breakthrough Enhancement Provides Unparalleled Turbulent Flow Modeling for
Vibro-Acoustic Simulation
Paris, France - September 19, 2016 - ESI Group, a leading innovator in Virtual
Prototyping software and services for manufacturing industries, announces the
release of VA One 2016. VA One is the only 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 seamlessly 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 unique capabilities for flexibly modeling complex loads and is able
to robustly 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
Until now, SEA models excited by turbulent flow, or other partially correlated
sources, were restricted to fitting analytical models; with consequent loss of
important details of the loading. This left users the choice of accepting a
loss of acoustic prediction accuracy or moving to more costly modeling
approaches. The General Surface Pressure (GSP) enhancement in VA One 2016
removes this roadblock by allowing acoustic modelers to directly apply
wavenumber spectra to SEA models. Taking advantage of the pre-processing
capabilities of VA One, users can define the loads directly from CFD data or
from their in house tools. Accurate design solutions can be obtained with
minimal modeling and computational time.

data can be imported into VA One from nearly any commercial CFD code.
Image: New, robust, easy-to-use tools in the VA One AVA module allow data to
be processed and convert the pressures to a wavenumber-frequency spectrum,
which can be applied as a load to the vibroacoustic model to predict interior
wind noise.
Enhanced Acoustic Predictive Capabilities for FE Models with Complex Flow
Addressing another important noise source, VA One 2016 provides enhanced non-
uniform acoustic FE mean flow predictive capabilities to accurately model the
effect of flow on muffler Transmission Loss (TL) via automated OpenFOAM®
analysis for reactive mufflers or when porous, sound absorbing muffler materials
such as fiberglass are present. The greater the muffler Transmission Loss is,
the quieter the muffler and exhaust. The challenge is to model the complex,
three-dimensional airflow in mufflers. This is addressed by VA One 2016 by
providing a high-level, automated solution for taking into account the flow
effect on muffler acoustics when complex geometries, perforated elements or
porous materials are present.
Performance and Productivity Enhancements
VA One 2016 delivers a wide 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. This
enhancement in calculation speed has also been particularly welcomed by the
aerospace industry where users seek ongoing performance improvements to BEM
modeling and support for calculation-intense stress failure predictions.
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.
"Customers have asked us for support in solving larger models, especially
Boundary Element Models, which require a long time to compute, particularly for
higher frequencies. These new enhancements to VA One take advantage of multi-
core processing on individual machines as well as distributed machines
(clusters) and provide significant improvements in overall model run time," said
Chad Musser, Director of Vibro-Acoustics Solution at ESI Group. "With the 2016
release of VA One, ESI delivers important enhancements that give our customers a
competitive cost and time advantage in bringing innovative products to market.
Our ability to consistently translate customer needs into software enhancements
underscores ESI's position as the industry leader in vibro-acoustic simulation,"
he added.
