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 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
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 is a verification case to attest the behavior of turbulence models and wall functions in the boundary layer of a turbulent flow. The velocity and the temperature are compared to the theoretical curves in a wall-resolved and a wall-modeled approach using the Algebraic y+ ... Per saperne di più
This example studies heat transfer in a composite two-dimensional structure. Four materials with distinct thermal conductivities k compose the structure. The top and bottom boundaries are facing environments respectively at 0°C and 20°C. The temperature distribution and the heat flux ... Per saperne di più
This tutorial model illustrates the use of the nucleate boiling heat flux features to compute the transient cooling of a cylindrical rod plated with nickel, and immersed in a pool of boiling water. The temperature and heat flux results obtained with a 3D time-dependent computation, with ... Per saperne di più
This example uses the thermal expansion of a laminated composite shell model to demonstrate the use of the feature Thermal Contact, Interface, applied on interfaces between layers in a laminated composite shell. The first study is computed neglecting this additional thermal resistance in ... Per saperne di più
This tutorial model demonstrates the use of the multiphysics coupling feature Thermal Connection, Layered Shell, Surfaces. In this model, three layered shells are connected to heat domains by interior and exterior boundaries. The results obtained with the Heat Transfer in Shells ... Per saperne di più
This model shows how to define a frequency-domain analysis of heat transfer. The 3-omega method uses the Cahill's equation to approximate the thermal conductivity of a sample from the measured temperature of a metal strip placed on top of it and subject to oscillating heating. The 2D ... Per saperne di più
This tutorial model compares the results between a domain approach and the Thin Moisture Barrier feature to simulate the moisture transport in a wall with a vapor barrier. The Thin Moisture Barrier feature neglects diffusion, two studies are proposed, a first one where diffusion is ... Per saperne di più
These tutorial models show how to use the tools to assist with defining surface-to-surface radiation models. In the first model, radiation direction symbols are used to find an unexpected configuration where the opacity is not correctly defined. In the other, the topology check ... Per saperne di più
