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 model extracts spice parameters for a silicon p-n junction diode. The spice parameters are used to create a lumped-element equivalent circuit model of a half-wave rectifier that is compared to a full device level simulation. In this example, a device model is made by connecting a 2D ... Per saperne di più
This tutorial demonstrates how an electrical circuit model of a MEMS resonator can be derived using the Parameter Estimation feature. The model is a modified Butterworth-Van Dyke circuit created using the Electrical Circuit interface and represents a Thin-Film Bulk Acoustic Resonator ... Per saperne di più
The heat distribution in a hollow pipe, whose ends are held at two different temperatures, is studied. The outside surface is assumed to be thermally isolated and the inner surfaces have radiation boundary conditions. The role of convection in the heat transfer is taken to be ... Per saperne di più
Wind strakes on a chimney impede the uniform detachment along the height of the chimney, which can induce vibrations and eventually lead to fatigue at the footing of the chimney. A stationary turbulent flow simulation is computed for a chimney with strakes mounted on a factory building. ... Per saperne di più
This tutorial shows how to set up a ray release based on the incident electric field at a boundary. First the Electomagnetic Waves, Frequency Domain interface is used to solve for the electric field of a plane wave. Then rays are released with initial intensity and polarization matching ...

Optical lenses of millimeter size cannot easily be analyzed with the Electromagnetic Waves, Frequency Domain interface on standard workstations due to the large number of finite element mesh elements required. This model explains how the Electromagnetic Waves, Beam Envelopes interface ... Per saperne di più
When a valve is closed rapidly in a pipe network it gives rise to a hydraulic transient known as a water hammer. The propagation of these hydraulic transients can in extreme cases cause failures of pipe systems caused by overpressures. This is a model of a simple verification pipe system ... Per saperne di più
Coplanar waveguide (CPW) bandpass filters can be designed using interdigital capacitors (IDCs) and short-circuited stub inductors (SSIs). This is a very efficient manufacturing method for producing bandpass filters, which can readily be implemented on a GaAs wafer. The Coplanar ... Per saperne di più
In this model, sound created by a vibrating piston radiates through a baffled pipe. The impedance is measured and then used in an impedance boundary condition that replaces the surrounding air domain. This technique can be employed to reduce solution time and memory usage for large ... Per saperne di più
The thermal stress in a layered plate is studied in this example. A plate consisting of two layers, a coating and a substrate layer, is stress and strain free at 800 degrees C. The temperature of the plate is reduced to 150 degrees C and thermal stresses are induced due to the difference ... Per saperne di più
