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.
In this example, a heterogeneous NMC (Nickel-Manganese-Cobalt) electrode structure is generated from tomography data using a Model Method. Time-dependent discharge and electrochemical impedance spectroscopy (EIS) simulations are then made on the full 3D geometry. A solid mechanics ... Per saperne di più
This model showcases how to solve for the scattered field when knowing the incident field for three different types of scatterer, i.e. an infinitely rigid one, a cavity and an elastic inclusion. This formulation can be useful when the scatterer is in the far-field of the source, such ... Per saperne di più
Prismatic lithium cells are widely used in electric vehicles and battery energy storage systems. This example demonstrates the use of the Lithium-Ion Battery interface for a full 3D prismatic battery equipped with two jelly rolls. The model defines a full so-called Newman model but ...

Coriolis flowmeters, also known as mass flowmeters or inertial flowmeters, measure the mass flow rate of a fluid traveling through it. It makes use of the fact that the fluid's inertia through an oscillating tube causes the tube to twist in proportion to the mass flow rate. Typically, ... Per saperne di più
This small tutorial model shows how to set up a model with a solid mechanics and a pressure acoustics domain including a common perfectly matched layer (PML). The PML is used to model an open or infinite domain for both the elastic waves and the pressure waves. Three configurations of ... Per saperne di più
A thin-walled frame with a central cutout is subjected to a random load. Although the stresses are far below the yield level of the material, damage accumulates over the load history. The Rainflow counting algorithm is used to define the load scenario and Palmgren-Miner linear damage ... Per saperne di più
These models demonstrate the usage of the user defined lumped port and lumped elements to introduce excitations and lumped circuit elements between volumetric conductors. Additional models show how to use impedance and transition boundary conditions to model the conductors, instead of ... Per saperne di più
Active magnetic bearings are often used for controlling the vibration level in mechanical systems. In this example, a motor driven rotor system in which the speed of the system is gradually increased is considered. The system vibrates due to existing imbalances. As the rotor speed ...

This model simulates atmospheric galvanic corrosion of a busbar, which includes a copper flange, an aluminum alloy flange in contact with a zinc nut and bolt. The Secondary Current Distribution interface is used to solve for the electric potential in electrode domain and Current ... Per saperne di più
This app simulates a micromixer based on an imported CAD geometry. The app shows how you can use the Application Builder to build an app that can handle CAD import and let the user interactively select boundary conditions. The app shows how this can be done without any programming using ... Per saperne di più
