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 app demonstrates the following: Geometry parts and parameterized geometries Using tables for user input parameters Visualization on a 2D cross-section of a 3D geometry Improved visualization and user experience when a geometry object (the air object) is hidden. Induction heating ... Per saperne di più
Microwave filters are used to eliminate unwanted frequency components in the output from microwave transmitters. They are typically inserted between a power amplifier and an antenna. The amplifiers are nonlinear and produce harmonics that must be eliminated with filters that have a ... Per saperne di più
This model investigates the wave propagation in a photonic crystal that consists of GaAs pillars placed equidistant from each other. The distance between the pillars determines a relationship between the wave number and the frequency of the light, which prevents light of certain ... Per saperne di più
The model estimates the AC breakdown voltage between parallel electrodes in air by simulating charge transport dynamics. To keep computations efficient, it is implemented in one dimension, though it can be adapted for different gases and extended to higher-dimensional setups. The ... Per saperne di più
Substrate Integrated Waveguides (SIW) can be used in antenna applications. Leaky waves from a slot array on the top surface of the SIW in this model generate a beam in a certain direction that can be steered by choosing a different operating frequency. Per saperne di più
This example demonstrates the Lithium-Ion Battery, Single-Ion Conductor interface for studying the discharge of a lithium-ion battery with solid electrolyte. The geometry is in one dimension and the model is isothermal. The behavior at various discharge currents and solid electrolyte ... Per saperne di più
Electrochemical supercapacitors feature relatively higher energy densities than conventional capacitors. With several advantages, such as fast charging, long charge–discharge cycles, and broad operating temperature ranges, electrochemical supercapacitors have found wide applications in ...

A fuel cell unit cell is modeled using the full Butler-Volmer expression for the anodic and cathodic charge transfer reactions. The anodic and cathodic overpotentials depend on the local ionic and electronic potentials, which are obtained from the charge balance equations for ionic and ... Per saperne di più
A simple equivalent circuit model approach is presented for Nickel metal hydride batteries. The 0D model consists of resistor, capacitor, current source and state-of-charge based voltage source (SOC). An Arrhenius type dependence is used to account for self-discharge. All model ...

The purpose of the app is to demonstrate and simulate the use of cyclic voltammetry. You can vary the bulk concentration of both species, transport properties, kinetic parameters, as well as the cycling voltage window and scan rate. Cyclic voltammetry is a common analytical technique ... Per saperne di più
