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.
A classic benchmark example in computational electromagnetics is to find the resonant frequency and Q-factor of a cavity with lossy walls. Here, models of rectangular, cylindrical, and spherical cavities are shown to be in agreement with analytic solutions. Per saperne di più
In small PEM fuel cell systems (in the sub-100 W range) no active devices for cooling or air transport are normally used. This is due to the desire to minimize parasitic power losses from pumps and fans, and to reduce the system complexity, size, and cost. The reactants at the cathode ... Per saperne di più
A stationary 3D model of a generic fuel cell cathode describing the mass fraction distribution of oxygen, water, and nitrogen, as well as the current distribution. The model uses Darcy's Law to describe convection, and couples this to Maxwell-Stefan diffusivities to also describe mass ... Per saperne di più
Zinc-Silver oxide (Zn-AgO) batteries are used in different industries due to their high capacity per unit weight. In this work, discharge of a Zn-AgO battery is simulated using the Battery with Binary Electrolyte interface. The electrochemical reactions in the positive and negative ... Per saperne di più
This model performs a topological optimization for a Tesla microvalve. A Tesla microvalve inhibits backwards flow using friction forces rather than moving parts. The design can be optimized by distributing a specific amount of material within the modeling domain. The goal is to maximize ... Per saperne di più
This model illustrates the refraction of light while passing through an optical prism using s– and p–polarized incident Gaussian beams. The prism boundaries are coated with anti–reflection coatings. It also calculates the reflectance and transmittance to analyze the performance of anti ... Per saperne di più
Diaphragm accumulators are essential components that store energy and regulate hydraulic systems. A flexible rubber diaphragm divides the hydraulic fluid from a compressible inert gas, typically nitrogen. These accumulators perform multiple tasks, such as temporarily storing hydraulic ...

This app demonstrates the following: Geometry parts and parameterized geometry A results table form object containing outputs Finned pipes are used for coolers, heaters, or heat exchangers to increase heat transfer. They come in different sizes and designs depending on the ... Per saperne di più
This example models wicking in a porous medium. Wicking is the phenomenon that occurs when a dry porous material is put into contact with a fluid: it will absorb the fluid due to capillary forces. The absorption will continue until an equilibrium is reached where the gravitational forces ... Per saperne di più
The present model example is based on Copper Deposition in a Trench model available in Electrodeposition Application Library. The nonuniform deposition along the trench surface leads to formation of a cavity/void. Since the Deformed Geometry interface cannot handle topological changes, ... Per saperne di più
