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 calculates the DC breakdown voltage between parallel electrodes in air using a detailed charge transport approach. It is currently one-dimensional for simplicity but can be extended to other gases and dimensions. The results closely match experimental data found in the ... Per saperne di più
The purpose of this model is to visualize the electric potential in an electrochemical cell, for example a battery. This is done at OCV and during operation. In a battery, this would correspond to OCV, discharge, and recharge. The potential profile is explained both for cells with planar ... Per saperne di più
This model is used on "Heat Transfer with Radiation in Participating Media and the Discrete Ordinates Method" to compare quadrature sets used in the method of discrete ordinates. The reference analytical solution of incident irradiation is obtained with 256 discrete directions. Errors in ... Per saperne di più
Finding acoustic eigenmodes in problems solved with linearized convected acoustic interfaces can be a challenging task. The solution will most often return several non-acoustic vorticity and entropy modes. These are highly damped waves that do not propagate at the speed of sound but with ... Per saperne di più
When evaluating the efficacy of treatments for ocular diseases, modeling and simulation can be used for pharmacokinetic analysis by visualizing drug concentration and how it spreads through the eye over time. In this simplified pharmacokinetic model of a human eye, a small patch is ... Per saperne di più
Because the atmosphere is nearly transparent to wavelengths in the range 8 to 13 µm (atmospheric window) for a clear sky, it is possible to cool down a surface even during a sunny day. This model compares the temperature distribution on a concrete block exposed to ambient and solar ... Per saperne di più
A gray body with a spherical cavity with various opening areas is simulated using the Heat Transfer, Surface-to-Surface Radiation interface. The emissivity for each case is computed and compared with the classical gray body theory. The COMSOL Multiphysics® result agrees very ... Per saperne di più
These models are featured in the blog post Analyze Violin Tone and Volume with Multiphysics Modeling. One applies acoustic-structure interaction to study how the air mode resonance is affected by the coupled vibrations in the violin body. The other uses a potential flow approximation to ...

In this model, an axial field magnetic gear with a gear ratio of 5:2 is modeled. Both the high-speed and low-speed rotors consist of permanent magnets and back iron. The low-speed rotor consists of five pole pairs, while the high-speed rotor consists of two pole pairs and the stationary ... Per saperne di più
This example shows how to model tissue ablation through applying RF radiation. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Study Radio Frequency Tissue Ablation Using Simulation". Per saperne di più
