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.
The "Smart Radiator Device," a multilayer structure, has the capability to control thermal emissivity at different temperatures. This multilayer structure is lightweight thus finds its application in spacecraft mission. The thermochromic vanadium oxide (VO2) material is the heart of ... Per saperne di più
Rayleigh-Bénard's convection cells is a classic in fluid dynamics. We present here two different approaches for computing the critical Rayleigh number above which the cells form. Per saperne di più
In this model, an axial field magnetic gear with a gear ratio of 5:2 is modeled. Both the high-speed and low-speed rotors consist of permanent magnets and back iron. The low-speed rotor consists of five pole pairs, while the high-speed rotor consists of two pole pairs and the stationary ... Per saperne di più
You can use the Moving Mesh or the Deformed Geometry interface to implement wrapping of a CAD part around one axis. This model demonstrates both how to implement this wrapping, as well as how to subsequently mesh the surrounding volume around the deformed part. A more detailed ... Per saperne di più
This model computes the specific acoustic radiation impedance of a very small circular vent in a flanged configuration. The model includes thermoviscous losses. The radiation impedance is fitted using a simple RL circuit which gives a simple lumped representation. The results are used ... Per saperne di più
This tutorial uses an equivalent circuit approach for modeling the performance of a lithium-ion battery, requiring no knowledge about the internal chemistry or structure of the battery. A 0D equivalent circuit battery model is defined based on a resistor connected in series with a ... Per saperne di più
A trimmer capacitor has a variable capacitance. One way of obtaining this is to use parallel facing electrodes with a variable overlap area. In this example, the capacitance can be changed by turning one electrode using a screwdriver. Typically a linear angular response is desired. ... Per saperne di più
In applications where pressure waves and elastic waves propagate in porous materials filled with air both thermal and viscous losses are important. This is typically the case in insulation materials for room acoustics or lining materials in car cabins. Another example is porous materials ... Per saperne di più
Stimulated Brillouin Scattering (SBS) describes a nonlinear interaction between light and sound. In optical fibers, SBS can be detrimental for power or communication purposes, but can be leveraged for sensing applications. The SBS gain spectrum quantifies the optic-acoustic mode ...

This tutorial model demonstrates the use of the features for heat transfer in layered shells, to account for the curvature of the layers when applying heat fluxes and heat sources. The results obtained with the Heat Transfer in Shells interface applied to a boundary (with extra ... Per saperne di più
