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.
Diesel particulate filters (DPFs) are designed to remove and filter soot (diesel particles) from the exhaust of diesel engine vehicles. The filters in such systems are typically structured with long, air-filled channels surrounded by a porous medium that retains the soot. Although the ... Per saperne di più
It is more difficult to generate laser emissions in the short-wavelength part of the visible and near visible part of the electromagnetic spectrum than in the long-wavelength part. Nonlinear frequency mixing makes it easier to generate new short wavelengths from existing laser ... Per saperne di più
This model simulates a simple three-dimensional axisymmetric Helmholtz resonator, a classic acoustics model of a resonating circuit with a known theoretical solution. The idealized version considered here consists of a tube and a closed volume in series which are exposed to a pulsatile ... Per saperne di più
This tutorial model shows how to model a microspeaker located in a smart phone including the radiation through and interaction with the acoustic port that connects to the exterior. The model demonstrates a linear frequency domain analysis as well as a nonlinear time domain analysis. A ... Per saperne di più
A differential line is composed of two transmission lines excited by two out-of-phase signals. This configuration is known to be useful to enhance signal-to-noise ratio. This example shows how to set up the differential microstrip lines using TEM type ports. Per saperne di più
This is a small 2D demonstration model that couples the Linearized Navier-Stokes, Frequency Domain, Solid Mechanics, and Turbulent Flow (k-epsilon) physics interfaces to model the vibrations of a plate located in a 2D viscous parallel plate flow. This type of model is used to model fluid ... Per saperne di più
A large reflector can be modeled easily with the 2D axisymmetric formulation. In this model, the radius of the reflector is greater than 20 wavelengths and the reflector is illuminated by an axial feed circular horn antenna. The simulated far-field shows a high-gain sharp beam pattern Per saperne di più
This is a 2D model of an anisotropic porous absorbing material. The absorption coefficient alpha are determined as functions of frequency for three different incidence angles. The example uses Periodic Floquet boundary conditions. The model uses two different methods for modeling the ... Per saperne di più
This three-phase induction motor model is used to compare with Testing Electromagnetic Analysis Method (TEAM) workshop problem 30. The Magnetic Fields physics interface is used to model the motor in the frequency domain at 60 Hz. The Velocity (Lorentz Term) feature is used to model the ... Per saperne di più
A plane electromagnetic wave propagating through free space is incident at an angle upon an infinite dielectric medium. This model computes the reflection and transmission coefficients and compares to the Fresnel equations. Per saperne di più
