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 benchmark model computes the valence band structure of an unstrained and a strained bulk GaN wurtzite crystal, as a tutorial for users who wish to set up multiple wave function components with the Schrödinger Equation interface. The model follows the formulation given in the ... Per saperne di più
Feeding antennas with proper signals can be difficult. The signal is often described as a voltage, and voltages are not well defined in electromagnetic wave formulations. There are several tricks to model voltage generators in such situations, and one is the magnetic frill. This model ... Per saperne di più
This app demonstrates the following: Using the knob form object Updating the geometry by rotating a knob Provides info if the results are above or below certain critical values Many trucks are equipped with cranes for handling loads and such cranes have a number of hydraulic ... Per saperne di più
This tutorial demonstrates the operation of a gyroscope based on design provided by Dr. James Ransley at Veryst Engineering, LLC. The model uses the Electromechanics coupling with the mixed finite element formulation in the Electrostatics interface. Per saperne di più
In this tutorial model, it is demonstrated how to incorporate a localized nonlinearity in a submodel. In this case, an initial elastic analysis reveals that a small region of a structure has stresses above the yield limit. To improve the results, an elastoplastic material model is added ...

The elastoacoustic effect is a change in the speed of elastic waves that propagate in a structure undergoing static elastic deformations. The effect is used in many ultrasonic techniques for nondestructive testing of prestressed states within structures. This example studies the ... Per saperne di più
Deposition of metallic lithium on the negative electrode in preference to lithium intercalation is known to be a capacity loss and safety concern for lithium-ion batteries. Harsh charge conditions such as high currents (fast charging) and/or low temperatures can lead to lithium plating. ... Per saperne di più
This tutorial shows how to model the tubular permanent magnet generator in 2D axisymmetry. The generator consists of a modular stationary stator and moving/oscillating slider. The stator is made of three-phase multiturn windings and an iron core. The slider is made of permanent magnets ... Per saperne di più
The Curve Digitizer application can be used to digitize/extract curves from images. This application provides an easy way to digitize a variety of 1D plots with different axes in Cartesian or Polar coordinate system. After a curve image is imported, the digitization is done in a few ... Per saperne di più
Portal Cranes are common when handling heavy loads. In this example, the Beam interface is used to compute the stresses in a portal crane designed for lifting 15 tons. Three load cases are considered: self weight, payload, and thermal expansion on a hot summer day. An internal hinge ... Per saperne di più
