Direct FSI Approach to Computing the Acoustic Radiation Force
In a follow-up to a previous blog post, we demonstrate a direct fluid–structure interaction approach for computing the acoustic radiation force in COMSOL Multiphysics®.
Modeling a Stacked Piezoelectric Actuator in a Valve
Piezoelectric valves are energy efficient, durable, and fast. You can model a key component of this device responsible for opening and closing the valve: a stacked piezoelectric actuator.
Part 2: Obtaining Material Data for Structural Mechanics from Measurements
Learn how to use nonlinear elastic and elastoplastic materials, as well as a method for using your measured data directly in COMSOL Multiphysics®. Part 2 of a series on hyperelastic materials.
Phase Decomposition Analysis of Loudspeaker Vibrations
A guest blogger from Dynaudio A/S discusses using COMSOL Multiphysics® to perform a phase decomposition analysis of the vibrations in a loudspeaker.
How Can I Build an Efficient Stirling Heat Pump?
Did you know that heat pumps are also called Stirling engines? These systems can operate on incredibly low temperature differences — some only need human body heat to work!
Using the Boussinesq Approximation for Natural Convection
Today, we compare the Boussinesq approximation to the full Navier-Stokes equations for a natural convection problem. We also show you how to implement the Boussinesq approximation in COMSOL Multiphysics software and discuss potential benefits of doing so.
Can We Hear the Shape of a Drum?
Over half a century ago, Mark Kac gave an interesting lecture on a question that he had heard from Professor Bochner ten years earlier: “Can one hear the shape of a drum?”
Simulating the Insertion of a Snap Hook
Snap hooks, a type of fastener that involves the insertion of a hook into a slot, are found in the automotive industry. Simulation can be used to analyze their insertion and removal.
