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
The microstrip patch antenna is used in a wide range of applications since it is easy to design and fabricate. The antenna is attractive due to its low-profile conformal design, relatively low cost and very narrow bandwidth. It is known that the antenna impedance will be higher than an ... Per saperne di più
Coriolis flowmeters, also known as mass flowmeters or inertial flowmeters, measure the mass flow rate of a fluid traveling through it. It makes use of the fact that the fluid's inertia through an oscillating tube causes the tube to twist in proportion to the mass flow rate. Typically, ... Per saperne di più
Angle beam ultrasonic units are used for nondestructive testing (NDT) of solid objects, such as metal pipes. They are especially useful for detecting flaws in and around welding areas, such as pores, small cracks, lack of fusion, etc. Angle beam NDT is often used where the straight beam ...

Micromirrors are used in certain MEMS devices to control optic elements. This example model illustrates a mirror that is initially actuated for a short time and then exhibits damped vibrations. It simulates a vibrating micromirror surrounded by air and uses the Thermoviscous Acoustics, ... Per saperne di più
Numerical modeling of Lamb waves, which belong to guided waves, is essential for the analysis and design of the structural health monitoring (SHM) systems for long range ultrasonic testing. The design of an SHM system based on guided waves consists of two main parts. In the first place, ... Per saperne di più
This tutorial model shows how to model car cabin acoustics using a hybrid FEM-ray approach. The particular example is that of a tweeter located in the dashboard of the car near the windscreen. A FEM based sub-model of the speaker and its immediate surroundings is used to compute a ... 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
An automotive midwoofer is modeled using the lumped parameter approach. The electrical and mechanical components are modeled using a lumped electric circuit, which is coupled to a finite element model for the acoustics using the Lumped Speaker Boundary feature. The large signal ... Per saperne di più
This tutorial shows how to include local nonlinear effects when simulating the acoustics of an exponential horn. Nonlinear effects become important when an acoustic horn is used for high amplitude signaling. The Nonlinear Acoustics (Westervelt) Contributions feature available for the ... Per saperne di più
