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.
Numerical modeling of Lamb waves, which belong to guided waves, is essential for the analysis and design of the structural health monitoring (SHM) systems for long range ultrasonic testing. The design of an SHM system based on guided waves consists of two main parts. In the first place, ... Per saperne di più
An electron gun must be able to draw a sufficient current and accelerate the electrons to the desired speed. The first part of an electron gun geometry presents unique design challenges because the emitted electron speeds are usually lowest there, and therefore the space charge density ...

The heat exchanger in this tutorial model contains a dynamic wall with an oscillating wave shape. The deformation induces mixing in the fluid and reduces the formation of thermal boundary layers. Hence, it increases heat transfer between the walls and the fluid. In addition, the wave ... Per saperne di più
This model shows how to analyze a simple, cantilever based, piezoelectric energy harvester. A sinusoidal acceleration is applied to the energy harvester and the output power is evaluated as a function of frequency, load impedance and acceleration magnitude. Per saperne di più
This example describes an array of heating tubes submerged in a vessel with fluid flow entering at the bottom. This is a multiphysics model because it involves fluid dynamics coupled with heat transfer. The pressure and the velocity field are the solution of the Navier-Stokes equations, ... Per saperne di più
Small heating circuits find use in many applications. For example, in manufacturing processes, they heat up reactive fluids. The device in this tutorial example consists of an electrically resistive layer deposited on a glass plate. The layer results in Joule heating when a voltage is ... Per saperne di più
Dielectrophoresis (DEP) occurs when a force is exerted on a dielectric particle as it is subjected to a nonuniform electric field. DEP has many applications in the field of biomedical devices used for biosensors, diagnostics, particle manipulation and filtration (sorting), particle ... Per saperne di più
A Gaussian electromagnetic wave is incident on a dense array of very thin wires (or rods). The distance between the rods and, thus, the rod diameter is much smaller than the wavelength. Under these circumstances, the rod array does not function as a diffraction grating (see the Plasmonic ... Per saperne di più
A tweeter is a high frequency driver used in loudspeaker systems. An ideal tweeter will produce a constant sound pressure level at a given distance in front of the driver independently of frequency, that is, a flat response. Ideally the tweeter will also, to a certain degree, maintain ... Per saperne di più
At the resonance frequency, the capacitive coupling between the turns causes the impedance of a coil to transition from inductive to capacitive. This application analyzes the resonance of a 5 turn spiral coil of copper equipped with a thin epoxy varnish insulation layer. The capacitive ... Per saperne di più
