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.
This model shows how to define a frequency-domain analysis of heat transfer. The 3-omega method uses the Cahill's equation to approximate the thermal conductivity of a sample from the measured temperature of a metal strip placed on top of it and subject to oscillating heating. The 2D ... Per saperne di più
This tutorial shows how to simulate coupled heat and moisture transport in an insulated roof structure, made of a load bearing and an insulation layer. The thermal insulation is facing the interior and there is a moisture barrier facing the exterior. The load bearing is capillary active ... Per saperne di più
In this example, wrinkling is studied in a cylindrical membrane of nonuniform thickness under axial and pressure loading. The membrane is modeled as an incompressible Mooney–Rivlin material. During axial stretching, certain portions of the membrane undergo wrinkling; however, the ... Per saperne di più
Some positive electrode materials are known to deteriorate in overcharged lithium-ion battery cells. Predominantly, manganese containing electrode materials such as LMO and NMC can loose capacity due to manganese dissolving from the materials at overcharge. This decomposition is a ...

In complex mechanical systems, it can be challenging to find an optimal (or even good enough) solution only through engineering insight or trial-and-error procedures. Using mathematical optimization methods can then be an efficient path to a better design. In this example, a link ... Per saperne di più
This tutorial model shows how to model car cabin acoustics using a hybrid FEM-ray approach. The particular example is that of a tweeter located in the dashboard of the car near the windscreen. A FEM based sub-model of the speaker and its immediate surroundings is used to compute a ... Per saperne di più
Chain drives are used for transmitting power from one shaft to another, located at some distance. This example simulates the dynamics of a chain sprocket assembly in 2D. The geometry consists of a roller chain wrapped around two sprockets. Both chain links and sprockets are assumed to be ... Per saperne di più
This model demonstrates how to use the built-in shape optimization functionality to improve the performance of a plate heat exchanger. The optimization reduces the path immediately in front of the inlets and outlets to increase the length of typical streamlines. This leads to a improved ... Per saperne di più
Usually limited to a specific region, corona discharges appear as a consistent luminosity. The attributes of steady glow corona discharges change depending on their polarity. Positive glow corona, also referred to as Hermstein's glow or ultra corona, presents a direct current (DC) aspect ... Per saperne di più
The Helmholtz filter is a popular technique for imposing a minimum length scale in structural topology optimization, but certain applications also call for a maximum length scale. This model demonstrates how to achieve this using an extra PDE filter. Per saperne di più
