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 installation verification application can be used to help verify that your COMSOL Multiphysics® or COMSOL Server™ installation works as expected on your hardware platforms and operating systems. The app automatically loads and runs a suite of test models and compares the results with ... Per saperne di più
This model uses the Semiconductor and RF modules to describe a photoconductive antenna (PCA). A laser pulse is applied on the surface of undoped LT-GaAs to generate electron-hole-pairs, which move under the influence of an external E-field creating a transient electric current pulse. ...

This example demonstrates the usage of the Scattered Field formulation to compute the scattering of light off of a single scatterer on top of a dielectric half-space. It uses the analytic Fresnel equations to design the background field. For a detailed introduction to this model, see ... Per saperne di più
In this model, an eigenfrequency analysis is performed to give a bandgap analysis of a 1D multilayer photonic crystal extending to infinity in +/- y direction. We perform the bandgap analysis for three different cases of material properties, as discussed in Chapter 4 of Ref. 1. Case ... Per saperne di più
This is a benchmark model for the 2D axisymmetric formulation of the Electromagnetic Waves, Frequency Domain interface that is available with the RF Module. The problem is to find the resonant frequencies and fields inside an axisymmetric cavity with rectangular cross-section and ... Per saperne di più
The transmission speed of optical waveguides is superior to microwave waveguides, because optical devices have a much higher operating frequency than microwaves, enabling a far higher bandwidth. This model is an example of a single step-index waveguide made of silica glass. The inner ... Per saperne di più
This verification model uses the Electromagnetic Waves, Boundary Elements interface to simulate the RCS of perfectly conducting sphere. The simulated result is compared to analytical calculation to verify the accuracy. Per saperne di più
The "Smart Radiator Device," a multilayer structure, has the capability to control thermal emissivity at different temperatures. This multilayer structure is lightweight thus finds its application in spacecraft mission. The thermochromic vanadium oxide (VO2) material is the heart of ... Per saperne di più
This shows how a Gaussian beam incident on a periodic structure can be efficiently simulated. This could be applied to structured surfaces like metasurfaces or diffraction gratings. Because of superposition, only a single unit cell needs to be simulated. This can provide extremely ... Per saperne di più
A plane wave is incident on a reflecting hexagonal grating. The grating cell consists of a protruding semisphere. The scattering coefficients for the different diffraction orders are calculated for a few different wavelengths. Per saperne di più
