World-leading Powerful Acoustics Simulation Tool
Optimizing the acoustic performance of designs is now easier with Actran, a unique and reliable acoustic simulation software from MSC. Backed by finite or infinite element methods (FE/IFE) and the Discontinuous Galerkin Method (DGM), Actran helps solve acoustic, vibro-acoustic, and aero-acoustic challenges.
The availability of a rich library of materials, elements, boundary conditions, solution schemes, and solvers sets Actran apart from other acoustic simulation solutions. It comes with an intuitive and user-friendly GUI that can be tweaked based on user preferences. Actran’s modular structure allows for easy deployment.
Actran is extensively used in the design of audio devices such as musical instruments, telephones, and other medical instruments like hearing aids given the ability to help understand sound propagation in complex media. It also finds its applications in the design of complex mufflers and silencers, and to understand sound absorption inside the passenger compartment of cars, trains and aircrafts.

Actran VibroAcoustics
Actran VibroAcoustics helps users to study the behaviour of structural vibration associated with an acoustic model. It has an extensive in-built library that comprises of visco-elastic media, porous or incompressible media, composite materials, or active components such as piezo-electric ceramics. Additionally, one can build a complex model by merging AeroAcoustics that will solve aero-vibro-acoustic problems.
VibroAcoustics is widely used in various industries such as Consumer Devices, FMCG, and Defense to name a few. It helps in solving noise-related problems for powertrains, intakes, exhausts, passenger compartment, audio, and HVAC in the automotive space, sound transmission through the cockpit, noise propagation in air distribution systems.
Actran AeroAcoustics
Actran AeroAcoustics helps in solving problems pertaining to sound generation and propagation mechanisms. It aids skilled engineers and designers across the world to simulate acoustic noise level of car interior, aircraft interiors, electronic devices, among others.
This simulation tool possesses the ability to predict the noise generation of turbulent flows and analyze the structure of a vibrating object, absorbent materials or resonators. Its high performing solvers and parallel processing features allows users to integrate Actran pre- and post-processing environments.
SNGR
Actran SNGR can accurately analyze and predict the noise induced by turbulent flows with the help of CFD solutions such as StarCCM+™, Powerflow™, SC/Tetra™, Fluent™, Star-CD™, or OpenFOAM™. The noise sources are synthesized using CFD analysis and then run as an acoustic computation.
Actran SNGR is relatively faster and more efficient than its counterpart aero-acoustic in terms of noise generation-related challenges. Equipped with high-performance solvers, Actran SNGR offers easy integration with Actran VI, and Actran VibroAcoustics.
