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.
In a cylindrical or prismatic battery cell, the active layers, current collector metal foils and separators are wound into a “jelly roll”. Additional tabs (metal strips) are welded to the current collector foils in order to conduct the current to the exterior of the cell can. The ... Per saperne di più
This is a benchmark model for a plane stress problem. The accuracy of the computed stress concentration is evaluated, and a mesh convergence study is performed for different element types. Per saperne di più
For transient acoustic problems, there are different sound pressure level metrics that have been defined in the literature and in measurement standards. These metrics are important to know when comparing results from a transient acoustic simulation to measurements from a sound level ... 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
This model demonstrates the Lithium-Ion Battery interface for studying the discharge and charge of a lithium-ion battery for a given set of material properties. The geometry is in one dimension and the model is isothermal. Battery developers can use the model to investigate the influence ... Per saperne di più
Electrochemical supercapacitors feature relatively higher energy densities than conventional capacitors. With several advantages, such as fast charging, long charge–discharge cycles, and broad operating temperature ranges, electrochemical supercapacitors have found wide applications in ...

In this tutorial, the vibrational behavior of a small aluminum plate with four waveguide structures is analyzed. This is an example of a structural component located in a device where elastic waves are propagating, like a smart speaker, an electric motor, or a MEMS device. The plate can ... Per saperne di più
The powder compaction process is becoming common in the manufacturing industry, thanks to its potential to produce components of complex shape and high strength. In this example, the compaction of iron powder to form an axisymmetric rotational flanged component is analyzed with capped ... Per saperne di più
In a diode or a transistor, when a p-n junction is reverse-biased (the p-side is connected to a lower potential than the n-side), ideally, no current should flow. However, due to minority carriers (electrons in the p-side and holes in the n-side), a small current, known as the reverse ... Per saperne di più
Micromirrors are used in certain MEMS devices to control optic elements. This model of a vibrating micromirror surrounded by air uses the Thermoacoustic-Shell Interaction user interface to model the fluid-solid interaction, and it thus includes the correct viscous and thermal damping of ...
