Join us and fellow engineers online for COMSOL Day: Acoustics. Listen to experts in the field of simulation, engage in product demonstrations, and ask questions to COMSOL technical staff. There will be interactive Tech Cafés run in parallel with the main sessions, covering parameter estimation & material properties and solving large acoustics models.

Please join us 10 minutes before the presentation starts to settle in and make sure that your audio and visual capabilities are working.
To start, we will briefly discuss the format of the day and go over the logistics for using GoToMeeting.
During this session, you will get an introduction to the latest news and trends in acoustics simulation. We will also briefly discuss some of the future developments and ideas for the Acoustics Module, as well as how to customize simulation apps for employees, coworkers, and customers to use with ease.
Get an overview of the capabilities for modeling the propagation of acoustic waves in coupled fluid and solid media in the COMSOL® software. The applications include nondestructive testing (NDT) units, flowmeters, and piezoelectric transducers.
High-fidelity numerical simulations are only achieved if material properties are well described. In acoustics, knowing the damping properties of fluids and structures can be challenging. For porous materials, the challenge may be even higher, as data provided by manufacturers is often sparse. Using COMSOL Multiphysics®, it is possible to estimate your material parameters from experimental measurements through optimization. Moreover, the properties of any gas mixture, like moist air, can be computed from first principles with thermodynamics.
Industry and government organizations will showcase how they are using multiphysics simulation to improve products and solve problems.

Acoustic propagation in structures with submillimeter features is the norm in consumer products like mobile devices, protective grills of loudspeakers, hearing aids, and perforates used in muffler systems. Common to all is that the inclusion of thermoviscous losses is essential to correctly predict the response. You will be introduced to the modeling techniques used to capture these effects in simulations.
When solving large acoustics models, it can be beneficial to tune the solvers for performance, stability, or memory consumption. This can, in many cases, be achieved using one of the predefined solver suggestions. The mesh and other options are also important. During this Tech Café, you can discuss how best to set up the solver configuration for your application with COMSOL engineers, who will also be answering your specific questions.
The virtual multiphysics development, design, and optimization of loudspeakers has reached a very mature state within the last five years. You will learn about the capabilities and latest modeling approaches available in COMSOL Multiphysics®, which will allow you to have a full virtual testing environment.
