modeling methods
Paris, France - December 2, 2013 - ESI Group, pioneer and world-leading solution
provider in Virtual Prototyping for manufacturing industries, announces the
latest release of VA One. VA One is used by manufacturers across the globe to
predict and resolve potential noise and vibration problems up front in their
development process, so they can deliver more competitive products and comply
with tougher noise regulations. VA One is the only software solution on the
market that enables the simulation of noise and vibration across the full
frequency range by seamlessly combining key vibro-acoustic modeling methods:
Finite Elements (FEM), Boundary Elements (BEM), and Statistical Energy Analysis
(SEA) in a single model.
"VA One was launched in 2005, with the ambition to provide VA simulation
engineers with an all-in-one software solution that could couple statistical and
deterministic modeling methods in a hybrid way, to allow the simulation of noise
and vibration across the full frequency range," says Sebastien Chaigne, recently
appointed Vibro-Acoustic Solution Director at ESI Group. "Today, ESI teams have
achieved the goal set in 2005. The latest version of VA One covers the full
spectrum of frequencies with great flexibility, delivering precise vibro-
acoustic simulation results. This unique capability is reinforced by an improved
workflow integration, to enable faster turnaround times."
VA One allows engineers to get a precise idea of a product's future vibro-
acoustic performance by setting up interior or exterior acoustic models, coupled
if necessary with a vibrating structure having various types of excitations.
The latest version of VA One now takes into account Hybrid Area junctions
between FE cavities and SEA panels: enabling engineers to improve the
characterization of small cavities, as required to develop home appliances,
cabins, or small vehicles, for example.
Furthermore, VA One now enables engineers to couple BEM and FE cavities. This
allows, for example, the simulation of a duct radiating noise externally; a
situation relevant to investigating the noise from HVAC (heating, ventilation,
and air conditioning) systems or automotive exhausts.
Joan Sapena, Acoustics R&D manager at Alstom Transport France, comments "VA
One's new functionality, connecting BEM to FE cavities, allows us to simulate
the vibroacoustic performances of complex HVAC ducts. This unique feature is
essential to ensure the right allocation and dimensioning of air ducts of on
board HVAC systems, from which radiation could not be effectively modeled
without using hybrid methods."
VA One provides the perfect environment to support all types of VA simulation
needs - from checking early design concepts through the detailed component
design phase, to troubleshooting in the virtual qualification test phase. It can
also be used for product cost and weight optimization by simulating various
sound package scenarios, while preserving product specifications.

Transmission Loss (TL) can now be calculated and plotted for all sources and
receivers, including BEM, Semi-Infinite Fluid and Diffuse Acoustic Field (DAF).
This is useful to users who need to model acoustic transmission loss through
walls and panels, at any stage of the design or development project.
New functionalities that provide improved customer experience and workflow
integration include GUI customization. Users can now customize their toolbars in
order to map their design process and thereby ease handovers between different
teams. VA One's Developer's Kit has been updated to support Python 3, allowing
for the creation of dialogs within VA One's environment.
