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.
A diplexer is a device that combines or splits signals into two different frequency bands, widely used in mobile communication systems. This model simulates splitting properties using a simplified 2D geometry. The computed S-parameters and electric fields at the lower and upper bands ... Per saperne di più
The design of antireflecting coating plays an important role to increase the transmission of the infrared light that propagates through optical structures such as lens and windows. In this model, we showcase how different bulk structures such as Si and CZT that has the bulk ... Per saperne di più
The present model demonstrates diffusion-controlled electrodeposition of copper on microstructured band electrode arrays (MEA). Mass transport by Fickian diffusion of copper ions is solved using the Transport of Diluted Species interface. Dendrite formation as a consequence of diffusion ... Per saperne di più
A Butler matrix is a passive beamforming feed network. It is a cost-effective feed network for phased array antennas because the circuit can be fabricated in the form of microstrip lines and is a viable solution for performing beam scanning without deploying expensive active devices. ...

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 app demonstrates the following: Importing measured data from a text file or use built-in functionality for data generation Automatically change solver options based on the input Dynamically update the equation display The app can be used to estimate parameters in models without ...

Transmission lines are used when the frequency of the electromagnetic signals is so high that the wave nature of the signals must be taken into account. A consequence of the wave nature is that the signals are reflected if there are abrupt changes of the characteristic impedance along ... 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
One way to design a filter is to use the element values of well-known filter prototypes, such as maximally flat or equal-ripple low-pass filters. It is easier to fabricate a distributed element filter on a microwave substrate than a lumped element filter, since it is cumbersome to find ... Per saperne di più
A Touchstone file describes the frequency responses of an n-port network circuit in terms of S-parameters. This can be used to simplify arbitrarily complex circuits. The Touchstone file can be obtained from numerical simulations or network analyzer measurements. The obtained file for a ... Per saperne di più
