Schedule

9:50 a.m.

Please join us 10 minutes before the presentation starts to settle in and make sure that your audio and visual capabilities are working.

10:00 a.m.

To start, we will briefly discuss the format of the day and go over the logistics for using GoToMeeting.

10:15 a.m.

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.

11:00 a.m.
Q&A/Break
11:15 a.m.
Parallel Session
Ultrasound & NDT

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.

Tech Café: Parameter Estimation & Material Properties

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.

Welcome Back: Some Useful Resources
1:00 p.m.

Industry and government organizations will showcase how they are using multiphysics simulation to improve products and solve problems.

Panelists include:

  • Anthony Bonomo, Naval Surface Warfare Center
  • Tim Whitwell, Tectonic Audio Labs
  • Patrick Dennis, Nissan
1:45 p.m.
Q&A/Break
2:00 p.m.
Parallel Session
Microacoustics

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.

Tech Café: Solving Large Acoustics Models

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.

2:45 p.m.
Q&A/Break
3:00 p.m.

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.

3:45 p.m.
Q&A/Break
4:00 p.m.

Anthony Bonomo
Naval Surface Warfare Center
Anthony Bonomo currently serves as the computational and structural acoustics specialist for the Acoustic Signatures Technology Division (Division 72) at the Naval Surface Warfare Center, Carderock Division. He graduated from the University of Maryland, College Park, in 2012 with degrees in mechanical engineering and jazz studies. While at Maryland, Anthony participated in the NREIP program and completed two summer internships working on structural acoustics projects at Carderock. These internship experiences led him to pursue graduate studies in acoustics at The University of Texas at Austin as a participant in the SMART Scholarship program, with Carderock as his sponsoring facility. At UT, Anthony conducted research in computational underwater acoustics at the Applied Research Laboratories, culminating in a master's degree awarded in 2014 and a doctor of philosophy in 2017. Anthony returned to Carderock as a full-time employee in January 2018. For the past two and a half years, he has been working toward improving the numerical methods employed by Division 72 and has worked on projects across the division.
