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 2D example of a vanadium flow battery demonstrates how to couple a secondary current distribution model for an ion-exchange membrane to tertiary current distribution models for two different free electrolyte compartments of a flow battery. The Ion-Exchange Membrane boundary node ... Per saperne di più
This model example investigates the transport of reactants and water in a high temperature PEMFC. The model includes mass and momentum transport phenomena in the flow channels, gas diffusion layers (GDLs), and porous electrodes, as well as electrochemical currents in the GDLs, the porous ...

A 180° Ring Hybrid (Rat-Race Coupler) is a four-port network with 180° phase difference between two ports. It is cheaper to manufacture this type of microstrip line component compared to a wave guide 180° hybrid junction, so called magic-T. The objective of this model is to compute the S ...

This tutorial illustrates how to use a reduced order model to compute the response of a structure subjected to three simultaneous loads having independent time histories. Reduced order models provide an efficient way to analyze problems within linear structural dynamics. Per saperne di più
The engine block of a car includes a cooling jacket to remove excess heat from combustion. The cooling jacket consists of open spaces in the cylinder block and the cylinder head. When the engine is running, a coolant fluid is pumped through the jacket to keep the engine from overheating. ... Per saperne di più
This example analyzes the deformation of a feeder clamp under stress. The clamp secures a feeder that carries high-frequency electromagnetic fields, and it’s important that it remains as straight as possible. Forces on the clamp include both those from the feeder as well as those on the ... Per saperne di più
A deceptively simple system of two species and two reactions, describing the autocatalytic conversion of a substance, is shown to display a surprisingly exotic behavior. Starting from a 0D CSTR description, a 2D reaction-diffusion problem is formulated showing rich patterns stemming from ... Per saperne di più
This is a model of acoustic absorption by a porous acoustic open cell foam. In porous materials the sound propagates in a network of small interconnected pores. Because the dimensions of the pores are small, losses occur due to thermal conduction and viscous friction. Acoustic foams are ... Per saperne di più
This example demonstrate two-phase flow in a porous medium which contains a low permeable lens. The heavier phase infiltrates the porous medium, so the low permeable lens is infiltrated only when a critical saturation at the outside is reached. Per saperne di più
Linear motors are used in many applications in need of translational motion. Typical characteristics of linear motor designs are high precision or quick acceleration. This model investigates a synchronous motor with three-phase winding on the stationary part and permanent magnets on the ... Per saperne di più
