MSC Actran is an engineering simulation application designed for analyzing acoustics, vibro-acoustics, and aeroacoustics in complex systems. It enables engineers to investigate sound propagation, structural vibration, acoustic radiation, and noise generated by fluid flow, helping them evaluate acoustic behavior during product development.
The software combines specialized finite element capabilities, a comprehensive library of material models, acoustic elements, including infinite elements, and high-performance solvers for large-scale simulation problems. Its graphical interface supports model preparation, analysis configuration, and result evaluation, with customizable options suited to different engineering workflows.
MSC Actran is used by automotive manufacturers, aerospace and defense organizations, and consumer product developers. Its modular architecture allows engineers to select capabilities according to their applications, from high-frequency acoustic analysis to vibration-related noise investigations and turbomachinery duct acoustics

Software Overview

Actran provides simulation tools for understanding how sound interacts with structures, materials, and moving fluids. Engineers can use it to study acoustic transmission and absorption, assess vibration-driven sound radiation, and investigate aeroacoustic effects in systems such as ducts and rotating machinery.
The application supports workflows that combine numerical simulation with experimental measurements. Measurement data can be incorporated into acoustic boundary conditions, source definitions, and pass-by noise studies, allowing engineers to compare simulated behavior with measured responses. Its radiosity solver is designed for high-frequency acoustics across large domains, while specialized duct-mode capabilities address acoustic propagation under non-uniform flow conditions.

Why Choose MSC Actran

MSC Actran is suited to engineering teams that need to evaluate noise and vibration behavior before physical prototypes are finalized. Its combination of acoustic simulation, structural vibration analysis, and aeroacoustic modeling helps users investigate sound transmission, radiation, and propagation within a unified engineering environment.
The ability to incorporate experimental measurements alongside simulation results is particularly useful when validating acoustic models against real-world data. Specialized capabilities for high-frequency radiosity and non-uniform duct flows also support demanding applications in automotive engineering, aerospace, shipbuilding, and turbomachinery development.

What's New

The 2026.1 release introduces improvements to radiosity modeling, experimental data integration, pass-by noise analysis, and acoustic propagation in ducts with non-uniform flows.
Radiosity: Simplified Model Preparation
Actran can automatically generate element sets for radiosity calculations, reducing the need to create them manually in ActranVI. Element-set size and angular thresholds can be optimized automatically to support convergence or specified manually when required. A single analysis can also include multiple meshes with different topologies, without grid or element-numbering conflicts.
Radiosity: Transmission Effects
The radiosity solver can account for acoustic energy transmitted through surfaces as well as energy absorbed by them. Users can assign transmission-loss (TL) data to surfaces through the PANEL component, supporting simplified transmission modeling for internal and external acoustic propagation. This capability is relevant to acoustic design in automotive, aerospace, and shipbuilding applications.
Radiosity: Sources Based on Structural Vibration
Vibrational or acoustic intensity data obtained from measurements or simulations can be used to define radiosity excitation. External data supports the calculation of spatially dependent injected power, while radiation-efficiency data can be supplied to improve acoustic radiation calculations.
Experimental Data Conversion Tool
The ActranVI experimental data conversion tool converts measurement data from CSV files into Actran-compatible formats. It supports generating NFF files for measurement-based boundary-condition meshes and PLT files for equivalent boundary-condition analysis, reducing the need for manual scripting when preparing time-domain and frequency-domain experimental inputs.
Unified Search Bar
An integrated ribbon search helps users locate commands and features by entering keywords. Suggestions appear as text is entered, and frequently used tools can be bookmarked for quicker access during subsequent sessions.
Workflow Manager: Accelerometer-Based Pass-By Noise Sources
The pass-by noise workflow includes a source type based on accelerometer measurements. Transfer functions are assigned to patches defined on vibrating components, and measured accelerometer data is applied to calculate acoustic contributions. Supported data formats include RPM-dependent, speed-dependent, and time-dependent inputs. Patch-wise contribution post-processing is also available.
Aeroacoustics and Turbomachinery: Duct Modes with Non-Uniform Flow
Modal extraction and injection support non-uniform mean flows, including axial shear and swirl. The capability covers Actran TM using the potential formulation, Actran DGM, and iTM modal matching with the Linearized Euler Equation and potential formulation. Supported geometries include 2D axisymmetric ducts in Actran TM and 3D annular and circular ducts. Flow profiles can be user-defined, fitted analytically from CFD data, or fully interpolated.
Other Improvements

Automatic coupling: An interface preview toggle allows users to inspect interfaces before confirming coupling.
Mesh editor: Additional meshing tools extend the framework introduced in Actran 2026.1.
ePowertrain noise workflow: Graphical refinements and improved selection of acoustic cover treatments strengthen workflow handling.
SEA Manager: Transmission-loss and absorption-coefficient curves from the acoustic Indicators tool can be reused directly in the SEA Manager.
Direct solver: Enhanced multithreading balances the factorization workload across threads.
