Modeling of NDT Methods Using COMSOL Multiphysics®

December 17, 2019

Active thermography, active ultrasonic, guided waves, acoustic emissions, and eddy current testing: 5 examples of how nondestructive testing (NDT) methods can benefit from multiphysics modeling.

Analyzing the Acoustics of a Head and Torso Simulator

September 6, 2019

Acoustics engineers designing hearing aids, cellphones, and headphones can perform standardized measurements faster and cheaper with simulation, as shown in this example.

How to Use Solver Suggestions in Acoustics Modeling

August 30, 2019

When you model large, industry-scale acoustics, ever find it challenging to efficiently solve the problem with the hardware at hand? Enter the solver suggestions in COMSOL Multiphysics®.

Samsung Amps Up Loudspeaker Designs with Simulation

July 29, 2019

Some organizations reach success and then shift the goal post. Take Samsung, for instance: Although they lead the market for televisions and smartphones, they set their eyes on another goal…

How to Automate Meshing in Frequency Bands for Acoustic Simulations

June 26, 2019

There is a large frequency range involved in acoustics phenomena, which means that modeling acoustics problems requires meshing a large wavelength range. COMSOL® offers an efficient way to do so.

Introduction to Modeling Acoustic-Structure Interactions in COMSOL®

June 12, 2019

To model an ASI problem, you need to account for the behavior of elastic waves in solids, pressure waves in fluids, and their interaction. The COMSOL® software includes interfaces for doing so.

Frequency Response of Mechanical Systems

June 5, 2019

Read this blog post for a detailed look at damped mechanical systems, a guide to setting up frequency-response analyses in COMSOL®, and a discussion of how to interpret your results.

Analyzing Topology Optimization of a Photoacoustic Spectroscopy Cell

May 24, 2019

Signals generated via photoacoustic spectroscopy are often weak and difficult to detect. Acoustic cells can be used to amplify the signal, but they need to be designed with sensitivity in mind.
