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 describes the behavior of a lithium-ion battery unit cell modeled using an idealized three-dimensional geometry. The geometry mimics the structural details in the porous electrodes. Such models are referred to as heterogeneous models. The modeling approach for heterogeneous ... Per saperne di più
This model shows how to set up a simulation of flow through a fractured reservoir. The reservoir includes a discrete fracture network (DFN), where the fractures have a randomized distribution of position, size, orientation and aperture. The model uses the Discrete Fracture Network Add ... Per saperne di più
An iron sphere in a magnetic field is an excellent textbook example to demonstrate the effects of a magnetic field interacting with a permeable material. This tutorial series is designed as an introduction to numerically modeling electromagnetic effects with COMSOL. This series ... Per saperne di più
This example treats the modeling of sub-surface flow where free convection in porous media is analyzed. The results are compared with published literature in the field. The model couples the momentum balance to an energy balance through an equation, dependent on temperature, being ... Per saperne di più
The level set method is well suited for problems with moving boundaries in which the geometry’s topology changes with time. A bubble of oil that travels up through water and finally merges with oil at the top causes this kind of topology change. For problems where the topology is ... Per saperne di più
In fuel cell power generators, a steam reformer unit typically produces the hydrogen needed for the cell stack. This example illustrates the modeling of a steam reformer. The reformation chemistry occurs in a porous catalytic bed where energy is supplied through heating tubes to drive ... Per saperne di più
This tutorial shows how to model tissue heating induced by focused ultrasound. First, the stationary acoustic field in the water and the tissue are modeled to obtain the acoustic intensity distribution in the tissue. The absorbed acoustic energy is then calculated and used as the heat ... Per saperne di più
This model solves the Testing Electromagnetic Analysis Methods (TEAM) problem 7, “Asymmetrical Conductor with a Hole”—a benchmark problem concerning the calculation of eddy currents and magnetic fields produced when an aluminum conductor is placed asymmetrically above a multi-turn coil ...

This model shows how to analyze a simple, cantilever based, piezoelectric energy harvester. A sinusoidal acceleration is applied to the energy harvester and the output power is evaluated as a function of frequency, load impedance and acceleration magnitude. Per saperne di più
The first stop for polluted water entering a water work is normally a large tank, where large particles are left to settle. Generally, gravity settling is an economical method of separating particles. If the fluid in the tank is moving at a controlled low velocity, the particles can be ... Per saperne di più
