Did you know SIMULIA XFlow is Acoustic Analysis Software?
In the traditional mesh-based approach to solving Computational Fluid Dynamics (CFD) problems, reliability is highly dependent on the quality of the mesh. Engineers spend most of their time working on the discretization of the mesh. Additionally, there are difficulties in dealing with the changes in the topology of the domain for problems involving the presence of moving parts or fluid-structure interaction. With its automatic lattice generation and adaptive refinement, SIMULIA XFlow Acoustic Analysis software minimizes user inputs while reducing time and effort in the meshing and pre-processing phase of a typical CFD workflow.
What is Acoustic Analysis Software?
XFlow is a particle-based Lattice Boltzmann technology solver for high fidelity Computational Fluid Dynamics (CFD) applications, and it is a part of SIMULIA’s Fluids Simulation offering.
Users of XFlow can manage complex CFD operations by utilising free-surface flows, intricate multiphase flows, fluid-structure interactions, and high-frequency transient simulations with actual moving geometries.
Engineers may focus more of their energy on iterating and optimising designs by using XFlow’s automatic lattice generation and adaptive refinement technologies, which decrease inputs and let users spend less time and effort during the meshing and pre-processing phase.
No matter the complexity, kind of gear, or lubrication method, users can gain substantial insights into system performance. By offering quantitative results forecasts, this can help reduce the number of physical tests needed.

XFlow Acoustic Analysis Software in practical use
- Aircraft design: XFlow can be used to predict the noise generated by aircraft engines and airframes. This information can be used to improve the design of aircraft to reduce noise emissions.
- Automotive design: XFlow can be used to predict the noise generated by automotive engines and exhaust systems. This information can be used to improve the design of vehicles to reduce or fine-tune noise emissions.
- Industrial noise control: XFlow can be used to predict the noise generated by industrial machinery. This information can be used to design noise control measures to reduce noise levels in the workplace.
XFlow for Acoustic Analysis
With its extensive post-processing features for acoustics, XFlow enables comprehensive acoustic analysis. Instead of simulating the radiation propagation of acoustic pressure waves, XFlow computes the propagation of these waves, allowing you to reduce the aerodynamic noise levels in and around vehicles.
The following acoustic post-processing features are enabled within XFlow:
- FFT: Fast Fourier transform, which can be used to decompose a signal into its frequency components.
- PSD: Power spectral density, which can be used to quantify the noise power at different frequencies.
- SPL: Sound pressure level, which is a measure of the loudness of a sound.
Windowing: A technique used to reduce the effects of noise and interference in a signal. - Signal filtering: A technique used to remove unwanted components from a signal.
- Band-pass filter: A type of filter that allows only frequencies within a specified range to pass through.These features allow a full acoustic analysis to be performed inside XFlow making post-processing a breeze.
Key benefits of using XFlow
- Effective and Economical: Reduce physical testing to save money and time on prototypes.
- Expeditious Development: Each stage of development can be used to analyse lubrication performance.
- Gain New Perspectives: Obtain precise forecasts of outcomes that cannot be measured experimentally.
- Comparing and improving: To maximise performance and optimise trade-offs, compare numerous design iterations.
