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.
Interfacial failure by delamination or debonding can be simulated with a Cohesive Zone Model (CZM). This example shows the implementation of a CZM with a bilinear traction-separation law. It is used to predict the mixed-mode softening onset and delamination propagation in a composite ... Per saperne di più
A stationary 3D model of a generic fuel cell cathode describing the mass fraction distribution of oxygen, water, and nitrogen, as well as the current distribution. The model uses Darcy's Law to describe convection, and couples this to Maxwell-Stefan diffusivities to also describe mass ... Per saperne di più
The elastic cantilever beam is one of the elementary structures used in MEMS designs. This model shows the bending of a cantilever beam under an applied electrostatic load. The model solves the deformation of the beam under an applied voltage. Per saperne di più
This model shows how to perform a submodeling analysis in order to evaluate structural stress. Using a submodel helps to compute the results in a refined geometry detail while applying loads and constraints in the global model. Per saperne di più
Small heating circuits find use in many applications. For example, in manufacturing processes, they heat up reactive fluids. The device in this tutorial consists of an electrically resistive layer deposited on a glass plate. The layer results in Joule heating when a voltage is applied to ... Per saperne di più
In this example, a dynamic analysis of a three-cylinder reciprocating engine is performed to investigate stresses generated during operation, thereby permitting identification of the critical components. Demand for high power output relative to the weight of the engine requires careful ... Per saperne di più
This example investigates the electrical performance of a cascaded cavity filter operating in the millimeter-wave 5G band with temperature changes. The thermal variations result in structural deformations of the structure. Thus, the resonant frequencies of the filter elements (cavities) ... Per saperne di più
As integrated circuit (IC) technology advances, with circuits becoming more powerful and compact, it is increasingly important to identify and prevent any cause of circuit failure. One particularly critical factor contributing to circuit failure is electromigration within the ... Per saperne di più
In this example, the Bergstrom–Bischoff material model is used to model the temperature and strain dependent behavior of High Density Polyethylene (HDPE) used, for example, to make liners for damaged pipes in oil and gas applications, or to make type IV hydrogen storage vessels for fuel ...

The primary defense of a submarine lies in its capacity to remain hidden during operation. As radio waves are strongly absorbed by sea water, sound navigation ranging, or SONAR, is one of the main methods used for the detection of submarines. SONAR systems are also used for underwater ...
