How to Use Solver Suggestions in Acoustics Modeling
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®.
Using the Port Boundary Condition in Acoustic Waveguide Models
By combining several Port boundary conditions, you can easily compute the transmission and insertion loss in exhaust and muffler systems. See more benefits of this feature for acoustics modeling.
Fine-Tuning the Design of Piezoelectric Transducers with Simulation
A variety of use cases and a variety of physics: Piezoelectric transducer designs need to account for electric currents, pressure acoustics, stress-strain, and acoustic-structure interaction.
How to Use the Boundary Element Method in Acoustics Modeling
Learn advantages and strategies for using the boundary element method (BEM) for acoustics modeling. Plus, we go over a hybrid approach that combines BEM with the finite element method (FEM).
Modeling Aeroacoustics with the Linearized Navier-Stokes Equations
Get a comprehensive introduction to aeroacoustics modeling, as well as the linearized Navier–Stokes equations and how to implement them in COMSOL Multiphysics®.
Using the Discontinuous Galerkin Method to Model Linear Ultrasound
You can easily model acoustically large problems, like linear ultrasound, with a predefined physics interface that uses a memory-efficient approach called the discontinuous Galerkin method.
New Octave Band Plot for Acoustics Simulation in COMSOL 5.2
COMSOL Multiphysics version 5.2 introduced a number of new features and functionality, including an acoustics-specific plot type called the Octave Band plot. This plot type provides you with an easy and flexible way to represent any frequency response, transfer function, sensitivity curve, transmission loss, or insertion loss — all of which are essential plots in many acoustics applications. Let’s learn a bit more about the Octave Band plot, while highlighting its various options and settings.
A Thermoviscous Analysis of Acoustic Radiation Forces
This past July, I had the pleasure of attending the 22nd International Congress on Sound and Vibration. In addition to running the COMSOL vendor booth with my Italian colleague Gabriele, I was also a presenter at the event. My presentation was based on a paper I wrote with Henrik Bruus and Jonas Karlsen that focuses on how to determine acoustic radiation forces including thermoviscous effects. Let’s explore acoustophoretic effects in greater detail and the research findings highlighted in my presentation.
