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 example demonstrates how to import a bitmap which can be used to simulate an image using ray tracing. The example is based on the Double Gauss Lens tutorial from the Ray Optics Module Application Library. The first study has been modified so that the Spot Diagram "auto-focus" tool ...

This tutorial models a DC glow discharge by solving fluid-type plasma equations fully coupled with the homogeneous and time-independent electron Boltzmann equation in the classical two-term approximation. The approximated Boltzmann equation is solved for each position of space and is ... Per saperne di più
Lithium-sulfur (Li-S) batteries are used in niche applications with high demands for specific energy densities, which may be as high as 500-600 Wh/kg. The chemistry is fairly complex, since multiple polysulfide species participate in the various charge transfer reactions. The chemistry ... Per saperne di più
This tutorial model solves for an inductively coupled plasma reactor in a mixture of SF6/argon. The model computes the fluid flow and gas heating. Important aspects and strategies for modeling electronegative discharges are discussed. Per saperne di più
This example shows how to perform parameter optimization on a lens system. The optimization is motivated by the replacement of one of the glasses in a prior optical prescription with a new glass having slightly different optical dispersion coefficients. The control parameters are the ... Per saperne di più
A square airbag made of a hyperelastic, compressible neo-Hookean material is inflated using pressurized air. Compressive stresses trigger wrinkling in some regions of the thin airbag. In this example, the wrinkling behavior is modeled using tension field theory, which gives a correct ... Per saperne di più
This example uses the Shallow Water equations to model the impact of a water wave on a column. A body of water with a height of 0.3 meters is initially contained behind a gate. At the start of the simulation, the gate is suddenly released and the body of water forms a wave moving toward ... Per saperne di più
In this example of a peristaltic pump, rollers squeeze a flexible tube and the compression drives a fluid through the tube. The model demonstrates how to use the Fluid-Structure Interaction interface. The main advantage of the peristaltic pump is that no seals, valves or other internal ... Per saperne di più
A battery’s possible energy and power outputs are crucial to consider when deciding in which type of device it can be used. A cell with high rate capability is able to generate a considerable amount of power, that is, it suffers from little polarization (voltage loss) even at high ... Per saperne di più
This tutorial performs steady-state and transient analysis of the response of a PIN diode to constant and pulsed radiation, respectively. The effect of radiation is modeled as spatially uniform generation of electron-hole pairs within the device. At high dose rates the separation of the ... Per saperne di più
