Designing Tidal Turbines That Are Safe for Marine Life
A guest blogger from Xi Engineering discusses how his organization is using acoustics simulation to study the impacts of tidal turbines on marine species.
Modeling Speaker Drivers: Which Coupling Feature to Use
Explore how to model 4 different speaker drivers, including moving-coil transducers, balanced armature receivers, piezoelectric drivers, and electrostatic drivers.
Modeling Piezoelectricity Using the Discontinuous Galerkin Method
COMSOL Multiphysics® version 6.0 introduced a feature for modeling piezoelectric devices that is more convenient than alternative methods. Here’s how to use it in your models.
Axisymmetric Solid Mechanics with a Twist
As of version 6.0, you can easily include circumferential displacements in 2D axisymmetric models using the Solid Mechanics interface. Check out one example here.
Validating an Acoustic Ray Tracing Simulation of a Chamber Music Hall
The well-known Konzerthaus Berlin theater boasts 3 separate halls: The Grand Hall, the Small Hall, and the modern Werner Otto Hall. Here, we explore the acoustics of the Small Hall with simulation.
Characterizing Piezoelectric Sensors for Nondestructive Testing
Piezoelectric sensors must be carefully designed and calibrated. Simulation can help make this process more efficient…

Acoustics Module, MEMS Module, Structural Mechanics Module: Which one should you use for your piezoelectric device modeling? Get a comprehensive overview of your options here.
Designing the Sound Absorption of Microlattice Structures
Using numerical simulation, you can design microlattice structures with sound-absorbing properties, and then print them via additive manufacturing without traditional manufacturing constraints.
Micromagnetic Simulation with COMSOL Multiphysics®
A guest blogger from Fudan University in China used the Physics Builder in COMSOL Multiphysics to create a “Micromagnetics Module” for performing micromagnetic simulations.
3 Examples of Optimizing Loudspeaker Components
Whether in a home theater system, gym, or massive concert venue, loudspeakers need to perform optimally. 1 way to do so is by performing a shape or topology optimization study of its components.
Simulating Wind Load on a Sports Car’s Side Door and Mirror
Vroom vroom: In this blog post, we use large eddy simulation (LES) and structural analysis to analyze wind loads and airflow on the door and side mirror of a sports car driving at high speeds.
Building a Solid Foundation for Understanding Seismic Waves
In 1906, there was the California earthquake. In 1908, there was the Lawson Report. In 1910, Harry Fielding Reid proposed the elastic rebound theory. Continue on a deep dive into seismology…
