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.
The model utilizes a dedicated mesh refinement study, Frequency Domain RF Adaptive Mesh, which dynamically refines the mesh in the region of interest. For the Application Library model Microstrip Patch Antenna, it increases the mesh resolution around areas with high field variations. The ... 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
Lamb-wave resonators are useful components for many radio-frequency applications. This example shows how you model an aluminum nitride Lamb wave resonator and perform eigenfrequency and frequency-response analyses to characterize the device. The tutorial uses the Electric Currents in ... Per saperne di più
This tutorial shows an approach to model the acoustic scattering off a submarine including the outer hull. The flooded volumes between the outer hull and the pressure hull are modeled with Pressure Acoustics, Frequency Domain (FEM) and the outside water domains with Pressure Acoustics, ...

This model illustrates the working principle of a passive electrodynamic bearing. An electrically conducting rotor rotating in a magnetic field produced by a permanent magnets induces eddy currents on the conducting rotor. The eddy currents, in turn, produce a magnetic field that opposes ... Per saperne di più
This model demonstrates how the sun causes 1.75 arcseconds of deflection for rays grazing the sun's surface as observed from the earth. Einstein predicted this value after refining his theory of relativity during World War I. Per saperne di più
A classic way of estimating pi is by using the Monte Carlo method. This involves randomly placing points inside a square and counting how many lie within a circle inscribed in the square. The ratio of points inside the circle to the number of points in total can be used to approximate ... Per saperne di più
This example compares moisture transport within two types of anisotropic porous medium. The first component defines a layered structure. The structure alternates between layers with high and low moisture diffusivity. So the moisture spreads more easily along the layers than transversely. ... Per saperne di più
Light collimation or focusing is a basic task often needed when working with lasers in the lab where singlets are used due to their simplicity. If a plano-convex lens is used for the task, there is a correct lens orientation that minimizes aberrations. A useful rule-of-thumb is to ... Per saperne di più
The present example simulates the steady-state flow in a radial pump using the mixing plane methodology. It solves for the averaged flow resulting from different blade positions of the rotor, thus circumventing the need to perform costly time-dependent simulations. Per saperne di più
