Actran AeroAcoustics
Whether noise comes from an air conditioning system, a rotating fan, or any other device that creates noise through turbulent flows, the sound generation and propagation mechanisms must be addressed to satisfy the ever increasing customer quality expectations. These systems are often required to operate for extended periods of time. Even low noise levels can significantly degrade the comfort for the user. With Actran, engineers from all industries have tools to predict and understand how to design quiet workplaces, quiet car and aircraft interiors, or silent electronic devices.
Actran AeroAcoustics is a module that features advanced capabilities to predict accurate and efficient noise generation of turbulent flows. Results from an unsteady flow simulation performed with CFD codes such as MSC's SC/Tetra™, Fluent™, Star-CD™, StarCCM+™, Powerflow™, OpenFOAM™ and others are used by Actran AeroAcoustics to compute aerodynamic noise sources. The acoustic propagation from these aerodynamic sources are then computed to provide users with acoustic results such as noise levels and directivity.
Using Actran AeroAcoustics, the noise generated by any turbulent flow can be thoroughly predicted. Users can benefit from all features of the Actran software suite to study the interaction between the aeroacoustic noise sources and a vibrating structure, absorbent materials, or acoustic traps such as resonators.

Statistical Energy Analysis approach offers an efficient solution to study noise and vibration propagation inside large systems at mid- and high-frequencies. The global system is reduced to a set of coupled subsystems and energy balance between them is computed.From FEA to SEABuilding a SEA model with classical approaches usually requires an access to experimental data or analytical expressions limiting the range of geometrical objects that could be handled. With Actran SEA module and its Virtual SEA approach, CAE engineers can use their existing Finite Elements vibro-acoustic models (mode shape and eigen values) to create a SEA model. Based on automatic or user-defined subsystems definition, SEA parameters are efficiently extracted from the Finite Elements model to perform sound and vibration analysis at mid- and high frequencies together with transfer path analysis regardless the availability of SEA expertise or experimental-based information. Combined with a unique frequency extrapolation method, the Actran SEA module offers the possibility to extend the frequency range validity of existing vibro-acoustic finite elements models to high frequency analysis.Complete system vibro-acoustic performances can be predicted,

CAEfatigue
CAEfatigue is a random response and vibration fatigue solver for the frequency domain plus a fatigue solver for the time domain. It works with mixed random and deterministic loadings or standard time domain-based loadings to provide fatigue life and damage predictions, as well as several forms of response statistics. It is exceptionally fast, easy-to-use and capable of handling very large models.
The software also offers tools for loads management including digital signal processing, as well as a Robust Design feature that allow users to analyze the robustness of their FEA models to variations in FEA solution parameters.
CAE fatigue – Premium Package
For many automotive and aerospace systems it is required to calculate both durability and to rule out the possibility of collision of individual components during severe base shake vibration conditions. Advanced frequency domain methods now exist to enable the durability assessment and response to be assessed in the same analysis. With the advanced random analysis output, it is possible to output displacement and/or velocity and/or acceleration and/or force RMS levels and Power Spectral Density (PSD) plots for both absolute and
relative responses.The specification of loads for durability is a very important topic. Ideally, any loads used in an analysis or in a laboratory-based test procedure, should be as close as possible to the Customers use of the product. In practice, the nearest scenario that can be achieved is to measure multi events and multi-input loads (with correlation) from prototype vehicles (test tracks) and then replay these in the laboratory or analysis environment. For analysis, this is feasible and is a commonly adopted method although it does not easily deal with the topic of test acceleration. For laboratory-based simulation, especially of parts or subsystems, there is a need (usually because of available test equipment) to simplify the loads down to single input load applied one at a time (e.g. X, then Y, then Z), which poses significant challenges. Two common approaches are currently used. First, an enveloping procedure can be applied to the loads where the multiple loads are combined into a single smoothed profile.CAEfatigue has created an industry first! We now provide the ability to conduct a full Spot Weld, Seam Weld and User Defined weld analysis in the Frequency Domain along with the more traditional methods used in the Time Domain. This capability will allow a full automotive vehicle analysis, that includes spot and seam welds, to be conducted with CF in either the Frequency domain or Time domain.
CAE fatigue – Frequency Package
CAEfatigue is designed to provide the user with both the random response results and the fatigue results from a structure undergoing loading input from a single random PSD with or without additional loading from deterministic inputs and mean offsets. Response outputs includes mean stress, RMS stress or strain, mean stress plus RMS stress or strain, moments, zero crossings, peaks per second and irregularity factor. Fatigue results including damage, life and margin of safety from a single random input.CAEfatigue offers all the input / output options mentioned for Base Shake loading plus the ability to use multiple random input PSDs (and cross PSDs) with mean offsets; i.e., data from a test rig with multiple events and multiple channels per
event plus a mean offset. This module offers random response and S-N and/or E-N fatigue results generated from the multiple simultaneous correlated load inputs, with any number of DOF’s, inputs, events and frequencies. Coupled with advanced random analysis, CF becomes a powerful tool for understanding output results for displacement, velocity, acceleration, force, stress, strain and fatigue (damage / life)For those who only have multi-channel, multi-event time histories, CAEfatigue offers a separate toolset called TIME2PSD. Historical loads conditioning procedures involve a series of user options that are hard for a typical engineer or designer to implement. Some of these have now been automated in the CF TIME2PSD approach. Window length (FFT buffer size), window overlap, and initial deletion of non-relevant parts of the signal can all be done automatically. The toolset provides a way to correctly eliminate sections of the time history that do not contribute to the damage. Conditioning is vital to ensure the damage from the time history is correctly transferred to the Power Spectral Density (PSD). The toolset also converts multi-input time histories to a PSD matrix that organizes, labels and tracks the PSDs to correctly account for cross correlation effects..

Arc Welding
With the Arc Welding module common arc welding processes are simulated. Residual Stress, strain and distortion as caused by the welding process are predicted. This enables an improved quality and dimensional control.
Simufact Welding allows to evaluate the impact of
vaious parameters, like: weld sequence, arc welding process parameters and fixturing strategy. Multiple weld robots can be configured. Weld fillets are modelled very easily using the internal fillet generator. Simufact Weldiing makes use of a comprehensive material database that can be extended by the user.

Metal powder bed fusion
Metal Powder Bed Fusion (PBF) is an advanced additive manufacturing technique that creates complex metal parts by selectively fusing layers of metal powder using a high-energy laser.
The process involves depositing a thin layer of metal powder and then using the energy source to melt and solidify the powder. As each layer fuses, a three-dimensional object is built up step by step with precise geometry and intricate internal structures. Simufact Additive can simulate the entire process and prevent costly issues during manufacturing.
Metal binder jetting
Metal Binder Jetting is an innovative additive manufacturing process where repeatedly a liquid binding agent is selectively deposited onto a layer of metal powder. Step by step they then form a 3D part but within a fragile and unfinished state, the 'green part’. After the printing process, the green part undergoes a secondary step to sinter the metal particles, resulting in a dense, functional metal component. Simufact Additive offers the first dedicated multi-physics Metal Binder Jetting sintering simulation solution focusing on distortion due to the post build sintering process and its automated distortion compensation.

Simufact Forming
Specialised forming simulation software for virtual testing and process design for component optimisation. Advanced simulation software orchestrates metal forming, unlocking the art of successful cold forming, hot forging, rolling, and stamping.
Cold Forming
Forming processes conducted significantly below the recrystallisation temperature of the material. These processes include typical upsetting and extrusion processes (e. g. for the production of bolts, nuts and rivets), but can also include coining, cold hobbing, thread rolling and last but not least drawing processes (e. g. wire drawing, tube drawing and profile drawing).
Hot Forging
Forming processes conducted above the recrystallisation temperature of the material. A typical process is hot forging, including closed die hot forging, auxiliary processes such as heating and cooling, cutting processes and preform operations (e. g. upsetting, bending, forge rolling and cross wedge rolling) as well as extrusion processes.
Heat Treatment
Methods in which, metallic workpieces (mainly steel pieces) are temporarily heated for the targeted improvement of the material’s properties.
Quench Temper
Quench temper enables the simulation of complex heat treatment processes with all necessary stages. In each of them the respective temperatures and heat transfer coefficients of resp. to dies and (furnace) environment can be specified in many ways as constant or changing.
Case HardeningCase hardening enables the simulation of direct hardening processes with all necessary stages. In each of them the respective temperatures and heat transfer coefficients of resp. to dies and (furnace) environment can be specified in many ways as constant or changing.Induction HeatingThis process type allows the modelling of an inductive heating process and therefore a more precise estimation of the resulting temperature distibution.
