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 investigates the National Institute of Standards and Technology (NIST) Gaseous Electronics Conference (GEC) reference cell in two dimensions using the Plasma, Time Periodic interface. A 2D example helps in understanding the physics without excessive CPU time. The cell is ... Per saperne di più
In this model, two fluids are separated by a solid elastic structure. An acoustic pressure wave impacts the structure resulting in a reflected wave and a wave transmitted with a loss through the structure. This model investigates the transmission loss through the structure. The effects ... Per saperne di più
This tutorial series describes in two different ways how to organize a more complex geometry. Per saperne di più
This model studies a part of a shell-and-tube heat exchanger where hot water enters from above. The cooling medium flows through the tubes that, in this model, impose a constant temperature at the walls. Furthermore, the tubes are assumed to be made of stainless steel and the heat flux ...

The models here showcase several use cases of the Circuit Extractor add-in, which is able to generate electric circuits from solved physics. A more detailed description of this tutorial model can be found in the blog post "Extracting Electrical Circuits from Electromagnetics ... Per saperne di più
This example models cathodic protection of a steel reinforcing bar in concrete. Three different electrochemical reactions are considered on the steel surface. Charge and oxygen transport are modeled in the concrete domain, where the electrolyte conductivity and oxygen diffusivity depend ... Per saperne di più
The present example simulates the turbulent flow over a 3D hill geometry using the Large Eddy Simulation (LES) interface with synthetic turbulence at the inlet boundary. Per saperne di più
This example extends the Fuel Cell Cathode tutorial to also include liquid water transport in the oxygen electrode. Liquid water is produced using a user-defined expression for vapor condensation, depending on the relative humidity level in the gas phase. An experimental capillary ... Per saperne di più
The zinc bromine redox flow battery is an electrochemical energy storage technology suitable for stationary applications. Compared to other flow battery chemistries, the Zn-Br cell potentially features lower cost, higher energy densities and better energy efficiencies. In the cell ... Per saperne di più
This model demonstrates the switching capability of a liquid crystal (LC) display cell in In-Plane Switching (IPS) configuration. The Oseen-Frank model is used to solve for the LC director (optical axis) distribution when a static electric field is applied. A Weak Form PDE interface is ... Per saperne di più
