Do your products suffer from flow-induced noise? Are you 
facing severe noise problems due to rotating blowers, fans 
or HVAC systems? Would you like to reduce noise at the 
design stage or quickly model the noise radiated by an 
open sunroof, wing mirrors or A-pillars, in order to 
improve your product quality? The aero-acoustics 
simulation tools from LMS help you evaluate the noise from 
unsteady flow phenomena like vortex shedding and turbulent 
boundary layers by coupling Computational Fluid Dynamics 
(CFD) methods with Computational Acoustics. The aero-
acoustics simulation tools from LMS offer a set of 
capabilities and user-friendly interfaces to transform the 
time-domain CFD data into equivalent aero-acoustics 
sources in the frequency domain. State-of-the-art acoustic 
BEM analyses will then return accurate predictions of the 
noise levels generated by these sources. Interfaces to 
leading CFD codes such as FLUENT, STAR-CD and CFX are 
available.
