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.
Hexagonal Plasmonic Color Filter
This model demonstrates how to perform simulations of an absorbing bandstop color filter, based on a hexagonal array of holes in a thin aluminum layer. The structure is hexagonally periodic but this example also shows how to set the model up as rectangularly periodic. Per saperne di più
Thermal Actuator Surrogate Model Application
The Thermal Actuator Surrogate Model application demonstrates how to accelerate computation for multiphysics analysis using a surrogate model. A surrogate model is a simpler, usually computationally cheaper model, which is used to approximate the behavior of a more complex, and often ... Per saperne di più
Electrostrictive Disc
This tutorial shows how you can use the Electromechanics interface in COMSOL's MEMS Module to model Electrostriction. Electrostrictive materials (e.g. PMN-PT) exhibit nonlinear strain as a function of electric field. This 2D axisymmetry model uses a parametric sweep of voltage to ... Per saperne di più
Topology Optimization and Verification of an Acoustic Mode in a 2D Room
This tutorial introduces the use of topology optimization in acoustics. The goal of the optimization is to find the optimal material distribution (solid or air) in a given design domain, here the ceiling of a 2D room, that minimizes the average sound pressure level in an objective ...

Thin Low Permittivity Gap Comparison
The thin low permittivity gap boundary condition is meant to approximate a thin layer of material with low relative permittivity compared to its surroundings. This boundary condition is available for electrostatic field modeling. This example compares the thin low permittivity gap ... Per saperne di più
Pratt Truss Bridge
This example is inspired by a classic bridge type called a Pratt truss bridge. You can identify a Pratt truss by its diagonal members, which (except for the outermost ones) all slant down in span-wise direction towards the bridge’s center. All the diagonal members are subject to tension ... Per saperne di più
Acoustics of a Particulate-Filter-Like System
This is the model of the acoustics in a particulate-filter-like system. Real systems, like diesel particulate filters (DPFs), are designed to remove/filter soot (diesel particles) from the exhaust of diesel engine vehicles. The porous medium in such systems are typically structured with ... Per saperne di più
Dipole Antenna with a Quarter-Wave Coaxial Balun
An antenna balun blocks undesirable currents on the outside of a cable. A quarter-wave coaxial balun (1:1) is one of the easiest designs: it works as a transformer and makes the input impedance from the inner conductor to the outer conductor infinite. This model simulates an antenna ... Per saperne di più
Neutralization of Chlorine in a Scrubber
This example studies the kinetics of the neutralization of chlorine gas in water solution. The model assumes that the fluid volume is perfectly mixed and constant. This means that the chlorine has dissolved to an almost saturated state (1·10-2 mol/m3) and that the hydroxide has also ... Per saperne di più
Pyroelectric Detector
This 2D axisymmetric model demonstrates the operation of a pyroelectric detector found in instruments for measuring laser energy. A disk of lithium niobate (LiNbO3) is sandwiched between two electrodes and connected to an external circuit. The disk is mounted on a ring-shaped ... Per saperne di più
