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 its simplest form, an optical ring resonator consists of a straight waveguide and a ring waveguide. The waveguides are placed close to each other, making the light affect each between the two structures. If the propagation length around the ring is an integral number of wavelengths, ...

This is an example of a model of an induction motor in which eddy currents are induced in the rotor by time-harmonic currents in the stator windings and the rotor's rotation. Induced currents in the rotor interact with the magnetic field that is produced by the coils to generate the ... Per saperne di più
An evanescent-mode cavity filter is resonant at a frequency lower than its original fundamental mode frequency. Evanescent mode resonance can be realized by creating a discontinuity or reactance inside the cavity. The basic model was modified by the addition of a metal box at either end ... Per saperne di più
See how to perform a vibration analysis of the crankshaft of a 3-cylinder reciprocating engine in this tutorial model. Due to the eccentricity of the crank-pin and balance masses on the crankshaft, it undergoes self-excited vibration under rotation. The crankshaft is modeled using solid ... Per saperne di più
In this example, wear of the friction material in a disc brake is studied. Quasistatic friction forces are prescribed from simple kinematic considerations. The geometry of the brake pad is continuously updated to account for the material removal due to wear following the well-known ... Per saperne di più
This example models an oil reservoir with two horizontal wells. The reservoir contains two phases, water and oil. Oil is recovered by injecting water through the bottom well, so the oil production rate and the water-oil production ratio over time are computed. Per saperne di più
A charge exchange cell consists of a region of gas at an elevated pressure within a vacuum chamber. When an ion beam interacts with the higher-density gas, the ions undergo charge exchange reactions with the gas which then create energetic neutral particles. It is likely that only a ...

Gas cells have several applications in the design of scientific instruments. A gas cell is used to define a high-pressure region within the instrument's main vacuum system. For example, in this application, note we are designing a high-pressure region 100 mm long, with an operating ... Per saperne di più
This model shows how to implement an anisotropic, incompressible, hyperelastic material for modeling soft collagenous tissue in arterial walls. The hyperelastic material model implemented is based on the articles: Holzapfel, G. A., Gasser, T. C., & Ogden, R. W. (2000), A new ... Per saperne di più
The electron energy distribution function (EEDF) plays an important role in the overall behavior of discharges. In this example, the formation period of an Argon plasma is studied with special attention paid to the EEDF. The plasma is created within a 4 cm gap by a DC source voltage of 1 ...
