A Quiet Revolution: Analyzing Electric Motor Noise via Simulation
The sound we hear from electric-powered machines is a multiphysics phenomenon: A motor’s electromagnetic activity sends vibrations through both the machine and the surrounding air.
Analyzing HIFU Propagation Through a Tissue Phantom
High-intensity focused ultrasound (HIFU) is used for surgery, cancer therapy, shock wave lithotripsy, and more. Learn about how simulation can be used to analyze this noninvasive technique.
Modeling Thermomechanical Fatigue in COMSOL Multiphysics®
You can analyze thermomechanical fatigue in COMSOL Multiphysics® using experimental data from fatigue testing and material parameters from literature. A guest blogger demonstrates…
How to Simulate a Piezoelectric Micropump
Learn how to combine piezoelectric materials with fluid-structure interaction effects, use a velocity-dependent formula, and set up disconnected mesh between the solid and fluid domains.
Modeling Acoustical Properties of Porous Media in COMSOL®
A guest blogger from the University of Sheffield introduces the Johnson–Champoux–Allard–Lafarge (JCAL) model for analyzing acoustical properties of porous media.
Modeling Parts Without Constraints in Your Structural Analyses
When building a solid mechanics model, there may be parts with prescribed loads but no constraints that can be reasonably applied. Learn different approaches and considerations for this scenario.
The North Pole Models Product Distribution Challenges for the Holidays
Today, a guest blogger from the North Pole discusses using simulation to find out if his boss will be able to fit down all of the chimneys this holiday season.
Keynote Video: Rapid Prototyping for Sonar Systems
Engineers at Northrop Grumman follow a 4-part rapid prototyping design phase: Design, manufacturing a prototype, testing and design verification, and manufacturing of the final design.
