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 studies the propagation of high intensity focused ultrasound (HIFU) though a tissue phantom. HIFU is used in many different biomedical applications such as thermal ablation of tumors, transcranial HIFU surgery, shock wave lithotripsy, etc. A HIFU transducer typically ... Per saperne di più
A tweeter is a high frequency driver used in loudspeaker systems. An ideal tweeter will produce a constant sound pressure level at a given distance in front of the driver independently of frequency, that is, a flat response. Ideally the tweeter will also, to a certain degree, maintain ... Per saperne di più
This model simulates an LED that emits in the infrared part of the electromagnetic spectrum. The device structure is made up of a single p-n junction formed by a layer of p-type doping near the top surface of an otherwise n-type wafer. This kind of device geometry is simple and cheap to ...

This model simulates a plasma at medium pressure (2 torr) where the plasma is still not in local thermodynamic equilibrium. At low pressures the two temperatures are decoupled but as the pressure increases the temperatures tend towards the same limit. Per saperne di più
This model investigates the National Institute of Standards and Technology (NIST) Gaseous Electronics Conference (GEC) reference cell in two dimensions using the Plasma, Time Periodic interface. A 2D example helps in understanding the physics without excessive CPU time. The cell is ... Per saperne di più
This model shows how to combine different types of material nonlinearity, such as creep and elastoplasticity. In this specific example you will perform a stress and nonlinear strain analysis on a thick cylinder under a nonproportional loading: an initial temperature increase followed by ...

In this example, a triaxial test is simulated using the Hardening Soil material model. The test consists of two stages; an initial isotropic compression followed by axial compression. A hyperbolic stress-strain relation is recovered. It is also verified that the asymptotic value of the ... Per saperne di più
In this example, triaxial and oedometer tests are simulated using the Modified Cam-Clay material model. A nonlinear stress-strain relation is recovered with the constant Poisson's ratio formulation. The hardening and softening behavior is recovered for normally consolidated and highly ... Per saperne di più
This model simulates the isotropic compression of naturally structured and artificially structured clays using the Modified Structured Cam-Clay (MSCC) material model. The aim of the example is to reproduce the compression behavior given in a benchmark for four structured clays. Per saperne di più
This example shows how to model a loudspeaker driver of the dynamic cone type, common for low and medium frequencies. The analysis is carried out in the frequency domain and thus represents the linear behavior of the driver. The model analysis includes the total electric impedance and ... Per saperne di più
