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.
Uncertainty quantification is used to study the effect of manufacturing variation on the performance of a 2D solidly mounted resonator (2D SMR). This tutorial shows how the resonant frequency is affected by thickness variations of the piezoelectric layer and the Bragg reflector layers. ... Per saperne di più
In this example, the dynamics of a hopping hoop is simulated. A rigid rolling ring with a point mass on the perimeter can, under certain conditions, jump up from the surface on which it is rolling. The effects of different parameters like initial velocity and friction are explored. You ... Per saperne di più
In this example, the Bergstrom–Bischoff material model is used to model the temperature and strain dependent behavior of High Density Polyethylene (HDPE) used, for example, to make liners for damaged pipes in oil and gas applications, or to make type IV hydrogen storage vessels for fuel ...

This space-dependent model describes a stirred semibatch reactor used for producing antibody–drug conjugates. The reactor is set up in 3D and the conjugation reactions, turbulent flow, and concentration fields are simulated as functions of time. The resulting yield and drug-to-antibody ... 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
A capacitive micromachined ultrasonic transducer (CMUT) is a micro-scale receiver that converts ultrasound to electrical signal for high-resolution imaging application. This CMUT design has optimized force-displacement characteristics for increased transduction efficiency. Central to the ... Per saperne di più
An Electromagnetic Band Gap (EBG) structure can be used to increase the isolation between antennas close to each other. The decoupling effect is not only a function of frequency but also polarization and coupling-plane configuration. When designing an EBG structure, one needs to make ... Per saperne di più
The suspension of a loudspeaker is designed to keep the membrane in place and avoid any rocking movement of the voice coil. At low frequencies, where the displacement of the membrane is significant, the stiffness of the suspension varies along the movement of the voice coil. This ... Per saperne di più
Laminated composite shells made of carbon fiber reinforced polymer (CFRP) are common in a large variety of applications due to their high strength-to-weight ratio. Evaluation of the structural integrity of a laminated composite shell for a set of applied loads is necessary to make the ... Per saperne di più
A cooling flange in a chemical process is used to cool the process fluid, which flows through the flange. The surrounding air cools the flange via natural convection. In the stationary model, the forced convection to the process fluid is modeled using a constant heat transfer ... Per saperne di più
