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 tutorial simulates a standard test and benchmark model for nonreflecting conditions and sponge layers for linearized Euler-like systems. It involves the propagation of a transient Gaussian pulse in a 2D uniform flow. The Convected Wave Equation, Time Explicit interface solves the ... Per saperne di più
In this model, the acoustics of the Small Hall in the Konzerthaus Berlin is simulated with ray tracing. A full study of the room is performed in 1/3-octave bands with 10 pairs of source-receiver positions. The room acoustic parameters are derived from the calculated impulse responses, ...

An ellipse with sound-hard walls has the interesting property that an acoustic signal emanating from one of the foci refocuses at the other focal point b/c seconds later, where b (in meters) is the major axis length and c (m/s) is the speed of sound. This model involves a Gaussian ... Per saperne di più
In this example, the mechanical impact of a golf club hitting a golf ball is studied. The contact between the two parts is modeled using a viscous penalty formulation to stabilize the dynamic event. To properly model the large deformation, the golf ball is defined using a hyperelastic ... Per saperne di più
A signal integrity (SI) analysis gives an overview of the quality of an electrical signal transmitted through electrical circuits, such as high-speed interconnects, cables, and printed circuit boards. The quality of the received signal can be distorted by noise from outside the circuit, ... Per saperne di più
It is possible to generate harmonics that are multiples of the frequency of laser light by using nonlinear optical materials. This model demonstrates second harmonic generation using transient wave simulation and nonlinear material properties. A YAG (lambda=1.06 micron) laser beam is ... Per saperne di più
Laser systems are an important application area in modern electronics. With nonlinear materials it is possible to generate harmonics that are a multiple of the frequency of the laser light. This model shows how a second harmonic generation can be set up as a transient wave simulation, ... Per saperne di più
Powder compaction is a popular manufacturing process not only in powder metallurgy, but also in the pharmaceutical industry. The Capped Drucker–Prager model is commonly used for simulating the compaction processes of pharmaceutical powders, where the material properties depend on the ... Per saperne di più
Simulation of Maxwell’s equations in the time domain is useful if the objective of the analysis is to observe a transient phenomenon, to find the time it takes a signal to propagate, or if the materials being modeled are non-linear with respect to the electric or magnetic field strength. ...

A stent is a wire-mesh tube used to open a coronary artery during angioplasty, a process for the removal or compression of plaque. Their design is of significance for percutaneous transluminal angioplasty with stenting. During this procedure, a stent is deployed into the blood vessel by ... Per saperne di più
