La Galleria delle Applicazioni raccoglie un'ampia varietà di tutorial e di app dimostrative realizzati con COMSOL Multiphysics in diversi ambiti applicativi, inclusi quelli elettrico, meccanico, fluidico e chimico. E' possibile scaricare i file dei modelli e delle app demo pronti all'uso e le istruzioni step-by-step per costruirli, e utilizzarli come punto di partenza per le proprie simulazioni.
Lo strumento di Ricerca Rapida permette di trovare i modelli che si riferiscono alla propria area di interesse.
Si noti che molti degli esempi qui presentati sono accessibili anche tramite le Librerie delle Applicazioni incorporate nel software COMSOL Multiphysics® e disponibili dal menu File.
In this model, two fluids are separated by a multilayer solid elastic structure. An acoustic pressure wave impacts the structure resulting in a reflected wave and a transmitted wave with a loss through the structure. This model investigates the transmission loss through the structure. ... Per saperne di più
This model analyzes Joule heating and thermal expansion in a bond wire in an LED. Its purpose is to estimate the temperature increase and the resulting mechanical stresses in the bond wire due to thermal expansion. The magnitude of these stresses can be used to assess the risk of fatigue ... Per saperne di più
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 ... Per saperne di più
This app demonstrates the following: Reading and importing data from an Excel®-file Exporting data to an Excel®-file Light theme The app computes the beam section properties and true stress distribution in a designated steel beam section. A broad range of American and European beam ... Per saperne di più
This is a benchmark model for flexible multibody dynamics. This model simulates the dynamic behavior of a planar four-bar mechanism when one of the joints has a defect. The out-of-plane motion in the mechanism, caused by the defect in the joint, is compared with the results from the ... Per saperne di più
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 ...

The katana is a legendary Japanese sword used by the samurai in olden days. Here, we present a simple model where we simulate a differential hardening process to explore some of the features of the katana.

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 ... Per saperne di più
Anechoic coatings are used on submarines to reduce sonar reflections. This model calculates the reflection, absorption, and transmission properties of an anechoic coating on a steel plate. The calculated results from this sub-model can be used in larger system scale models, for example, ... Per saperne di più
A magnetic diaphragm is a flexible, thin structure that interacts with magnetic fields to perform mechanical or sensing functions. When subjected to an external magnetic field, the diaphragm deforms due to magnetomechanical interactions, converting magnetic energy into mechanical ... Per saperne di più
