There are products which have requirements that require manufacturers to limit noise levels and meet environmental and government standards. Engineers need productive tools to design, refine, and validate prototypes throughout the development cycle.
Covering the widest range of industry applications and engineering tasks and meeting the latest international standards, our vibroacoustic simulation solutions help analyze noise quality in designs. Simcenter offers indoor and outdoor acoustic simulation in an integrated solution that guides your team to make informed decisions during the early stages of design so you can optimize your product's acoustic performance. A unified and scalable modeling environment, combined with efficient solvers based on NASTRAN technology and easy-to-interpret visualization capabilities, allow you to quickly obtain information about the acoustic performance of your product.

Simcenter offers an extensive library of accurate models for predicting aeroacoustic noise sources, including steady-state models, direct models (DES/LES), propagation models, and acoustic perturbation equation solver (APE).

Create aeroacoustic sources close to noise emitting turbulent flows as calculated from a CFD solution and calculate their acoustic response in the external or internal environment. For example, you can predict cabin noise inside cars and aircraft due to wind loads acting on the windows and structural body of the vehicle. In addition, other apps also allow you to assess noise from heating, ventilation, and air conditioning (HVAC) and environmental control system (ECS) pipelines, train boogies and pantographs, cooling fans, ship and aircraft propellers, and much more. more.

Boundary Element Method

Often used for outdoor acoustics problems, the boundary element method (BEM) is ideal for problems involving very complex geometries that can be challenging to model for the FEM method. The BEM method helps to simplify the external acoustic simulation as only the external surface mesh of the geometry is required. This simplifies the modeling process and reduces degrees of freedom in the simulation model, which will result in easier analysis.

Ray Acoustics

Performing acoustic simulations in high frequency ranges is not always possible with standard finite element method (FEM) and boundary element method (BEM) technologies. In response to this,  Ray Acoustics enables you to competently and accurately perform acoustic analysis for high frequencies and efficiently and accurately perform various acoustic and audio comfort simulations in vehicles, covering the entire auditory frequency range. Parking sensors and near-field ADAS sensors are a good example of a use case where lightning acoustics can cooperate with your project, as it gives you the opportunity to quickly evaluate the performance of these ultrasonic transducers and sensors that operate at frequencies of 40 kHz and beyond.
