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 tutorial is a benchmark model that reproduces the Testing Electromagnetic Analysis Method (TEAM) Problem 32, which evaluates numerical methods for the simulation of anisotropic magnetic hysteresis. A hysteretic three-limbed laminated iron core is subject to a time-varying magnetic ... Per saperne di più
This example investigates the electrical performance of a cascaded cavity filter operating in the millimeter-wave 5G band with temperature changes. The thermal variations result in structural deformations of the structure. Thus, the resonant frequencies of the filter elements (cavities) ... Per saperne di più
The principle component of a quadrupole mass spectrometer is the mass filter which is used to filter ions with different charge to mass ratios. The quadrupole mass filter has been well studied over the years, Ref. 1 and the physics and optimal design are well understood. In a real ... Per saperne di più
This model demonstrates the analysis of lightning surges on high voltage transmission line towers. Lightning carrying a current of 10 kA struck one of the tower's shielded wires. The induced voltage at the three-phase conductors are computed. Some highlights of this model: Perform ... Per saperne di più
The coaxial cable (coax) is one of the most ubiquitous transmission line structures. It is composed of a central circular conductor, surrounded by an annular dielectric, and shielded by an outer conductor. This model computes the electric and magnetic field distribution inside of the ... Per saperne di più
Microlithography lenses are used to project the image of an integrated circuit onto a silicon substrate. This tutorial demonstrates how to create a 21-element fused silica lens which has a NA of 0.56 which is designed to be used at a wavelength of 248nm. The lens, which has a total ...
