This model computes an electromagnetic-heated busbar with surface-to-surface radiation and compares the results with the busbar model without radiation. The surface emissivity of copper is varied between 0.1 (blank material), 0.3 (partially oxidized), and 0.7 (heavily oxidized). A more ... En savoir plus
Analyzing resonances is essential when designing loudspeakers. Resonances can come from various sources in a loudspeaker, with the diaphragm being a significant one. There are numerous traditional approaches to address diaphragm resonances, each with its own benefits and drawbacks. A ... En savoir plus
This document explains how to install and run COMSOL Multiphysics® and COMSOL Server™ with Amazon Elastic Compute Cloud™ (EC2™). This requires that you have first acquired a Floating Network License (FNL) or COMSOL Server License (CSL) from COMSOL. The license manager ... En savoir plus
This simple tutorial model shows how to set up a parametric sweep over a number of frequency bands (octaves or 1/3 octaves) and remesh once per band. A frequency sweep is performed within each band, which now has an adequate mesh resolution. This approach saves some computational effort ... En savoir plus
As integrated circuit (IC) technology advances, with circuits becoming more powerful and compact, it is increasingly important to identify and prevent any cause of circuit failure. One particularly critical factor contributing to circuit failure is electromigration within the ... En savoir plus
Switched reluctance motors work on the principle of reluctance torque. The stator and rotor will interact to minimize the reluctance for the flux path. This application simulates the behavior of the motor when the stator winding is excited with a step voltage and when the rotor is at a ... En savoir plus
Model used as demonstration in the APEI/AES session on August 11. https://audioproducteducationinstitute.org/speakers-and-microphones-simulation-and-testing/ The geometry is invented and uses parts from two models: https://www.comsol.com/model/head-and-torso-simulator-acoustics-74381 ...

This application uses the shrinking core model to study the reduction of iron ore pellets. A 1D model of a packed bed containing iron ore pellets is modeled. The bed filling pellets initially consists of solid phase FeO. The pellets are reduced by CO, and the solid core shrinks leaving a ... En savoir plus
A spherical hydrophone consisting of a PZT ceramic, a coating material, and a cable is modeled in 2D axisymmetry. The Receiving Voltage Sensitivity (RVS) is computed for an incident plane wave and compared to an analytical solution from the reference for an ideal spherical hydrophone. ... En savoir plus
The purpose of this model is to introduce the specular reflection in Surface-to-Surface Radiation using the ray-shooting algorithm. Different parameters are available to the user to yield better accuracy in the results when using the ray-shooting algorithm. The model is a standard ... En savoir plus
