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.
Tutorial example of a Erlang SEIR model for the epidemic of COVID-19. The model is validated against data from China, Sweden, and the US. Parametric estimation is done using the reported deaths over time. The tutorial investigates the impact of social distancing on the progress of the ... Per saperne di più
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
Unwanted arcing can have serious adverse effects on electrical and electronic equipment and systems. To improve the understanding and prediction of arc dynamics, it is crucial to conduct multiphysics simulations of transient arc processes. This model features a 3D simulation of transient ...

This model simulates an electrodeless lamp with argon/mercury chemistry. The low excitation threshold for mercury atoms means that even though the mercury is present in small concentrations, its behavior dominates. There is strong UV emission from the plasma at 185 nm and 253 nm. The UV ... Per saperne di più
In this tutorial model, a six step thrust bearing is analyzed. A step thrust bearing consists of a stepped bearing surface on which the end of the shaft rotates. The entire assembly is submerged in a lubricant. The shaft collar is assumed to be spinning without any axial motion in the ... Per saperne di più
Underground train grids span large areas under London, Paris, New York, and other cities. The building regulations require strict noise standards, and failure to comply could result in significant losses in the market prices of developments. Therefore, train-induced noise has to be ...

In this example, a simplified micromechanical model of a unit cell with periodic boundary conditions is analyzed. The homogenized elastic and thermal properties of a composite material are computed based on individual properties of fiber and matrix. A comparison of numerical values are ... Per saperne di più
This example illustrates how to model the transport of different contaminants through a ceramic water filter candle with an activated carbon core. These types of water filters can be found in table top gravity filters, as well as attached to the faucet or as part of a larger reverse ... Per saperne di più
In COMSOL Multiphysics, you can import mesh and interpolation data created by other software for use in your simulations. You can also export data created in COMSOL Multiphysics to use in other COMSOL models and applications as well as other software. This document and accompanying ... Per saperne di più
The goal with this app is to explain experimental electrochemical impedance spectroscopy (EIS) measurements and to show how you can use a simulation app, along with measurements, to estimate the properties of lithium-ion batteries. The app takes measurements from an EIS experiment and ... Per saperne di più
