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.
This model studies the natural frequencies of a pre-tensioned string using the 2D Wire interface. This is an example of “stress stiffening”; in fact the transverse stiffness of wire elements is directly proportional to the tensile force. Strings made of piano wire have an extremely high ...

This example illustrates how to combine different Creep material models. Here a Norton–Bailey model (primary creep) is combined with a Norton model (secondary creep). This example is a continuation of the model thermally induced creep. Per saperne di più
The triaxial test is one of the most common tests used in laboratory soil testing. The soil sample is normally placed inside a rubber membrane and then compressed maintaining a radial pressure. In this model, a vertical displacement and a confinement pressure are applied on the sample ... Per saperne di più
In this example, wrinkling is studied in a cylindrical membrane of nonuniform thickness under axial and pressure loading. The membrane is modeled as an incompressible Mooney–Rivlin material. During axial stretching, certain portions of the membrane undergo wrinkling; however, the ... Per saperne di più
Active magnetic bearings are often used for controlling the vibration level in mechanical systems. In this example, a motor driven rotor system in which the speed of the system is gradually increased is considered. The system vibrates due to existing imbalances. As the rotor speed ...

Laminated shells made of carbon fiber reinforced polymer (CRFP) are common in a large variety of applications due to their high strength-to-weight ratio. The widespread attention to laminated shells is due to their diverse applications in aerospace, marine, automotive, and various ... Per saperne di più
In this example, the importance of including elastic deformations when analyzing heavily loaded fluid-film bearings is investigated. The structural parts are modeled using the Solid Mechanics interface, while the pressure in the lubricant is determined by the means of the Hydrodynamic ... Per saperne di più
A benchmark model of the Rainflow counting algorithm compares results between ASTM and COMSOL fatigue module using a flat tensile test specimen. An extension is made for the cumulative damage calculation following the Palmgren-Miner model and results are compared with analytical ... Per saperne di più
In this tutorial model, the acoustics of the human ear canal are investigated. The output includes the input impedance and the transfer impedance, as well as the level transformation from the entrance to the ear drum. The geometry of the ear canal used is based on measurements from test ... Per saperne di più
This model shows how to combine different types of material nonlinearity, such as creep and elastoplasticity. In this specific example you will perform a stress and nonlinear strain analysis on a thick cylinder under a nonproportional loading: an initial temperature increase followed by ...
