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.
An operational amplifier (op-amp) is a differential voltage amplifier with a wide range of applications in analog electronics. This tutorial models an op-amp connected to a feedback loop and a capacitive load. The op-amp is modeled as an equivalent linear subcircuit in the Electrical ... Per saperne di più
This tutorial model simulates a pair of straight conical bevel gears. The gears are modeled as rigid, but one of the gears is fixed while the other is hinged on a rigid bar. The rigid bar is also hinged at a point lying on the axis of the fixed gear. A transient analysis is performed to ... Per saperne di più
A cooling flange in a chemical process is used to cool the process fluid, which flows through the flange. The surrounding air cools the flange via natural convection. In the stationary model, the forced convection to the process fluid is modeled using a constant heat transfer ... Per saperne di più
This model demonstrates how to perform a hearing aid acoustic feedback response analysis, including both the in-ear hearing aid and the hearing aid cassette. The hearing aid modeled is a ReSound OMNIA™ device from GN Hearing A/S. The hearing aid is tested on a combined pinna and ear ... Per saperne di più
Due to the large differences in length scales in a lithium-ion battery, with the thickness of the different layers typically being several orders of magnitude smaller than the extension in the sheet direction, a lithium-ion battery is often well represented by a one-dimensional model. ...

This model computes the transmission probability through an RF coupler using both the angular coefficient method available in the Free Molecular Flow interface and a Monte Carlo method using the Mathematical Particle Tracing interface. The computed transmission probability determined by ... Per saperne di più
Many engineering structures consist of thin and slender components, where a full solid model will result in extremely many small elements. For such structures, it is much more efficient to use shell or beam elements. In this tutorial and verification model, it is shown how to connect ... Per saperne di più
This example exemplifies how to model thermal curing using the base package of COMSOL Multiphysics. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Modeling the Thermal Curing Process". Per saperne di più
The process of filling a water balloon is a vivid example for the interaction of fluid pressure and a nonlinear structural material. This model demonstrates how straightforward a FSI simulation model is set up in COMSOL. Per saperne di più
This is a model of the secondary current distribution in a zinc electrowinning cell. The model investigates the impact on the current distribution when changing the electrode alignment in a parametric study. The geometry is in 2D. Per saperne di più
