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.
Microstrip filters can be fabricated directly on a printed circuit board (PCB) with a microstrip line going from the input to the output. Along the microstrip line there are a number of stubs of certain lengths and widths. The design of the filter involves choosing the impedance of the ... Per saperne di più
Mixed-mode S-parameters describe the responses of a circuit with balanced ports excited and terminated by two types of modes: common and differential modes. They are calculated using a full S-parameter matrix of a four-port network that is composed of four single ended lines. This ... Per saperne di più
This model analyzes the electromagnetic, mechanical, and acoustical characteristics of the OWS-1943T-8CP (discontinued) speaker. Beside certain details, the geometry, material properties, and measurements are copyright by Ole Wolff. Starting from the geometry of the speaker, an ... Per saperne di più
This tutorial simulates the turn-on transient (forward recovery) of a simple PIN diode, based on the book "Fundamentals of Power Semiconductor Devices" by B. J. Baliga (p. 242, 2008 edition). The diode is current driven with a constant ramp rate of 1e9, 2e9 and 1e10 A/cm^2/sec and a ... 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. ...

This study simulates the thermal behavior of a computer Power Supply Unit (PSU). Most of such electronic enclosures include cooling devices to avoid electronic components to be damaged by excessively high temperatures. In this model, an extracting fan and a perforated grille cause an air ... 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

When simulations are involved in the development of mobile devices, consumer electronics, hearing aids, or headsets, it is necessary to consider how the transducers interact with the rest of the system. Here, we show an analysis of the interaction between a vibration isolation mounting ... 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
