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 model moisture transfer and induced swelling in a paperboard roll subject to varying ambient conditions. The material properties of the paperboard are anisotropic. Per saperne di più
Impedance tubes are used for estimating the surface impedance of various samples, for example, a layer of porous material used for sound insulation. This model shows how the five material parameters of the Johnson-Champoux-Allard model can be estimated from the pressure at two ... Per saperne di più
Several different approaches to optimizing a ten-turn axisymmetric coil are presented. First, the current in each turn is adjusted with the objective of having a uniform magnetic flux density along the centerline. Second, the currents are adjusted to minimize power dissipation with a ... Per saperne di più
In small PEM fuel cell systems (in the sub-100 W range) no active devices for cooling or air transport are normally used. This is due to the desire to minimize parasitic power losses from pumps and fans, and to reduce the system complexity, size, and cost. The reactants at the cathode ... Per saperne di più
The majority of 3D CAD files include only the geometry of the product to be manufactured. For finite element analysis, however, you find yourself often in a situation where additional geometry is needed, for example, to analyze the flow inside or outside a device. This tutorial, ...

A model of a thermal microactuator requires the coupled simulation of electric current conduction with heat generation, heat conduction, and structural stresses and strains due to thermal expansion. The purpose of this model is to demonstrate how to access the cluster computing ... Per saperne di più
This model shows how to model an electrolyte-gated organic field-effect transistor based on a general drift–diffusion model. The model uses the Transport of Charge Carriers interface and the Electrostatics interface. The transistor characteristics are visualized. Formation of the EDLs in ... Per saperne di più
Centrifugal pumps are used in various applications and can be found in many industries. The size of the pump in this model is typical for automotive applications. This model shows how to set up rotating machinery simulations using the frozen rotor approximation for modeling centrifugal ... Per saperne di più
