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.
Every electrical device has some resistance. That is, when a voltage difference is applied across any two terminals of the device, there will be a directly proportional current flow. This model demonstrates how to compute the resistance of a short section of copper wire. The convergence ... Per saperne di più
In a reciprocating piston engine the connecting rods transfer rotating motion into reciprocating motion. The connecting rods are constantly under high stresses and the load increases with the engine speed. A failure of one part in the engine usually results in a replacement of the whole ...

This model and presentation show how to model anisotropic properties of fibers in a heat transfer simulation. Because the fibers' orientation is not easy to define explicitly, the curvilinear coordinate interface is used to define the fiber orientation. The fibers have high thermal ... Per saperne di più
It is possible to generate harmonics that are multiples of the frequency of laser light by using nonlinear optical materials. This model demonstrates second harmonic generation using transient wave simulation and nonlinear material properties. A YAG (lambda=1.06 micron) laser beam is ... Per saperne di più
Laser systems are an important application area in modern electronics. With nonlinear materials it is possible to generate harmonics that are a multiple of the frequency of the laser light. This model shows how a second harmonic generation can be set up as a transient wave simulation, ... Per saperne di più
Topology optimization of the Navier-Stokes equations is encountered in different branches and applications, such as in the design of ventilation systems for cars. A common technique applicable to such problems is to let the distribution of porous material vary continuously. In this ... Per saperne di più
This example illustrates the modeling of vibration and noise in a 5-speed synchromesh gearbox of a manual transmission vehicle. A transient multibody analysis is performed to compute the gearbox vibration for the specified engine speed and external load. The normal acceleration of the ... Per saperne di più
An electrostatically actuated MEMS resonator is simulated in the time and frequency domains. The device is driven by an AC + DC bias voltage applied across a parallel plate capacitor. The dependence of the resonant frequency on DC bias is assessed, and frequency domain and transient ... Per saperne di più
When simulating surface-to-surface radiation, we rely on the view factors between elements of diffuse surfaces that emit and receive radiation. To compute surface-to-surface radiation in a given geometry, operators are created by the heat interface and can be used to evaluate view ... Per saperne di più
This example shows how to use the Parameter Estimation and Experiment features in the Reaction Engineering interface for optimization with multiple experimental data input files. The application finds the Arrhenius parameters of a first order reaction where Benzene diazonium chloride ... Per saperne di più
