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.
Because the atmosphere is nearly transparent to wavelengths in the range 8 to 13 µm (atmospheric window) for a clear sky, it is possible to cool down a surface even during a sunny day. This model compares the temperature distribution on a concrete block exposed to ambient and solar ... Per saperne di più
This model studies the heat conduction in a building structure separating two floors from the external environment. Four materials with distinct thermal conductivities k compose the structure. The exterior and interior boundaries are facing environments respectively at 0°C and 20°C. The ... Per saperne di più
This model illustrates the greenhouse effect in a box covered by a plate and exposed to sun radiation over a day. The temperature variation is monitored in two cases: with a plate made of glass, transparent in the solar spectral band and opaque for the ambient solar band with a fully ... Per saperne di più
1D model of a thermal energy storage (TES) system consisting of a packed bed of pellets. Three approaches for heat transfer in porous media are compared: A one-equation local thermal equilibrium (LTE) model A two-equations local thermal nonequilibrium (LTNE) model A multiscale ...

This model studies the heat conduction in a thermal bridge made up of an iron bar and an insulation layer that separates a hot internal side from a cold external side. The heat flux between internal and external side and the maximum temperature on the external wall are compared them with ... Per saperne di più
This example is about the modeling of the fiber drawing process. Thermal fiber drawing is a process in which a comparatively thicker structure is heated and drawn into extended lengths of microstructured fiber. This process is done by passing them through the furnace and pulling them ... Per saperne di più
The Highly Accelerated Stress Test (HAST) is a testing technique to precipitate failure of electronic devices under elevated temperature and high humidity environment. This model demonstrates the structural analysis of a plastic encapsulated IGBT module under the HAST testing condition. ... Per saperne di più
Droplet evaporation is ubiquitous in everyday life and is essential in many industrial processes, such as inkjet printing, cleaning/coating of surfaces, and phase change heat transfer. This model demonstrates how to model phase transition by a moving exterior boundary condition using ... 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
This model evaluates the temperature distribution in 3 buried cables in a situation where the soil surface temperature is known. The temperature profile obtained with a thermal circuit approach for the cables is compared with a FEM approach. The thermal circuit properties are established ... Per saperne di più
