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.
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
This model shows one approach for obtaining a broadband impulse response by combining ray-tracing and finite element methods. The combination is done all within COMSOL® and uses idealized filters. In this example, the simulation results are further compared to an analytical solution ... Per saperne di più
Various boundary conditions are employed in the computation of homogenized properties for heterogeneous materials. The choice between periodic or homogeneous boundary conditions depends on whether the infinitesimal volume is modeled as a repeating unit cell (RUC) or a representative ... Per saperne di più
Light rail transit (LRT) systems often utilize DC power for train propulsion. In these systems the potential gradients in the rails may induce stray currents, which corrode adjacent metallic structures. In this example, the Cathodic Protection interface, using Edge Electrode nodes, is ... Per saperne di più
Whenever dimensions in waveguides become small compared to the viscous and thermal boundary layers it is necessary to model acoustics using thermoacoustics. In the present model the thermoacoustic wave field in a shallow uniform waveguide is modeled and compared to an analytical solution. Per saperne di più
This app demonstrates the following: Navigation system using toggle buttons in the ribbon and Back/Forward buttons in the settings window Selecting predefined or user-defined materials Using a table for input of geometry objects The app simulates a rotor bearing system consisting of ...

Cross-coupled forces present in a hydrodynamic bearing often act as a negative damping in a rotor. Near the critical speed, this may lead to uncontrolled vibration of the turbocharger causing a risk of bearing failure. In this example, the influence of the cross-coupling forces on the ...

Chemical vapor deposition (CVD) is an important step in the process of manufacturing microchips. One common application is the deposition of silicon on wafers in low pressure reactors to obtain uniform deposition thicknesses. This example models the coupled reaction kinetics, fluid ...

Atmospheric corrosion occurs when metallic structures are exposed to humid air forming a thin electrolyte film in the range of up to a few hundred micrometers. The model presented here accounts for charge transport as well mass transport involving 10 species and 6 homogeneous ... Per saperne di più
A bipolar membrane consists of one anion-selective, and one cation-selective membrane, in contact with each other. The combined cation and anion selectivity makes the bipolar membrane highly impermeable to all ions, with the exception of H+ and OH- which are formed by water splitting ... Per saperne di più
