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.
In this model, a linear magnetic gear system with a gear ratio of 11:4 is modeled. The liner magnetic gear is assumed to be infinitely long with the modular structure that is repeating on either side. Only a single modular section is modeled by using the customized linear periodic ... Per saperne di più
Photonic crystal devices are periodic structures of alternating layers of materials with different refractive indices. Waveguides that are confined inside of a photonic crystal can have very sharp low-loss bends, which may enable an increase in integration density of several orders of ... Per saperne di più
This model solves the Boltzmann equation in two-term approximation for a mixture of nitrogen and oxygen representing a background gas of dry air. Electron transport coefficients and source terms are computed by suitable integration of the electron energy distribution function over ... Per saperne di più
A classic benchmark example in computational electromagnetics is to find the resonant frequency and Q-factor of a cavity with lossy walls. Here, models of rectangular, cylindrical, and spherical cavities are shown to be in agreement with analytic solutions. Per saperne di più
This tutorial model is kindly provided by Riccardo Vietri, James Ransley and Andrew Spann at Veryst Engineering, LLC. Piezoelectric micropumps are frequently used in medical applications because of their ability to precisely control the metering of very small volumes of fluids or gases. ... Per saperne di più
This example demonstrates a benchmark test showing that Electric Currents in Layered Shells physics interface can be used to obtain the same results as when the model is solved with the Electric Currents interface based on a solid 3D structure. Per saperne di più
This tutorial model solves for a one-dimensional capacitively coupled plasma reactor in a mixture of argon/oxygen. Important aspects and strategies for modeling electronegative discharges are discussed. Per saperne di più
A planar dielectric slab waveguide demonstrates the principles behind any kind of dielectric waveguide such as a ridge waveguide or a step-index fiber. This model solves for the effective index and fields of a dielectric slab waveguide and compares the solution to analytic results. 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
This is a model of an adapter for microwave propagation in the transition between a rectangular and an elliptical waveguide. Such waveguide adapters are designed to keep energy losses due to reflections at a minimum for the operating frequencies. To investigate the characteristics of the ... Per saperne di più
