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 example demonstrates the usage of the Scattered Field formulation to compute the scattering of light off of a single scatterer on top of a dielectric half-space. It uses the analytic Fresnel equations to design the background field. For a detailed introduction to this model, see ... Per saperne di più
This model describes the corrosion of magnesium (Mg) alloys in physiological environments using a phase-field formulation. The approach couples Mg dissolution kinetics with ionic transport, enabling the transition from activation-controlled to diffusion-controlled regimes to be captured. ... Per saperne di più
Manual design optimization typically requires numerous sweeps over a parameterized geometry, but it does not guarantee optimal performance under given conditions. Shape optimization removes the need for explicit parameterization and can achieve comparable or even better performance in a ... Per saperne di più
A small building block of integrated photonics, i.e., a Silicon-on-Insulator taper, is considered. For a larger system design, it might be useful to determine the phase delay such a device introduces. Here, we showcase the layout needed to do it in COMSOL, including a proper Port ...

In this extension of the model Optical Scattering off a Gold Nanosphere, the transmission spectra due to spherical nanoparticles of gold with varying radii dispersed in glass are computed and mapped onto the CIE 1931 and sRGB colorspaces. For a description of this model, see the ... Per saperne di più
This example model demonstrates four different approaches for computing the integrals of fields over arbitrarily placed geometries that can be re-positioned without having to re-solve the model. This approach is also useful if you want to integrate the results of a model over different ... Per saperne di più
This model simulates a holographic page data storage system. The studies include the recording and retrieval processes. The object beam encrypting 8-bit data is focused into a holographic material by a Fourier lens (Fourier transformation). In the recording process, the object beam ... Per saperne di più
This tutorial demonstrates how to model a Silicon-on-Insulator (SoI) Modulator – a well-known optics device configuration that takes advantage of the free-carrier plasma dispersion effect and allows for the electrical control of the optical waveguide properties. The simulation couples ... Per saperne di più
This example of a plasmonic waveguide filter shows that the waveguide rejects the electromagnetic radiation of the wavelength between 1.4 um and 1.6 um, but allows the rest of the wavelength. The silver material can be modeled using the Drude-Lorentz approximation, with ε∞ = 3.7, ωp = 13 ... Per saperne di più
This model showcases a nail penetration experiment into a layered battery. It couples the Solid Mechanics, Lithium-Ion Battery, and Heat Transfer interfaces. A nail is punched into a sandwiched battery consisting of two electrodes and a separator. As soon as the nail connects both ... Per saperne di più
