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 example models the radiation of fan noise from the annular duct of a turbofan aeroengine. When the jet stream exits the duct, a vortex sheet appears along the extension of the duct wall due to the surrounding air moving at a lower speed. The near field on both sides of the vortex ...

Many engineering structures consist of thin and slender components, where a full solid model will result in extremely many small elements. For such structures, it is much more efficient to use shell or beam elements. In this tutorial and verification model, it is shown how to connect ... Per saperne di più
In the diffuse double layer and within the first few nanometers of an electrode surface, the assumption of electroneutrality is not valid due to charge separation. Typically, the diffuse double layer may be of interest when modeling very thin layers of electrolyte including those in ... Per saperne di più
A tubular centrifuge is a type of centrifugal separation device that is often used for separation of very fine solid particles from a liquid. It can be run in both a continuous and batch type configurations. The device usually consists of a cylindrical rotating bowl with a large aspect ... Per saperne di più
This model uses the Reacting Flow multiphysics interface to simulate a methane steam reformer. The model accounts for the interactions between the chemical reactions, the transport of species, the fluid flow, and the heat transfer in a porous medium. Per saperne di più
This a continuation of the permanent magnet motor model available here . In this model, an heat transfer analysis has been performed to compute the temperature rise for various stator current and rotor speed. A detailed analysis on torque, and losses in iron and copper have then been ... 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
This tutorial model presents a study showing the transient negative mobility and the negative differential conductivity effects in xenon. The stationary and time dependent Boltzmann equation in the two-term approximation is used to compute the electron energy distribution function. ... Per saperne di più
This example demonstrates how to use the Poroelasticity multiphysics coupling between the Solid Mechanics and Darcy's Law interfaces to model linear biphasic poroviscoelastic behavior of soft biological tissues. The implementation is verified using two numerical benchmarks from the ... Per saperne di più
A 3D model of an acoustic trap in a glass capillary with a bias flow through the capillary. The acoustics is actuated by an oscillating electric potential across a piezoelectric transducer, inducing mechanical vibrations in the solid, and an acoustic pressure field in the fluid. The heat ... Per saperne di più
