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.
Permanent magnet (PM) motors are used in many high-end applications, such as in electric and hybrid vehicles. An important design limitation is that the magnets are sensitive to high temperatures, which can occur through heat losses caused by currents, particularly eddy currents. In ... Per saperne di più
Just like optical lenses focus light, electric and magnetic lenses can be used for focusing beams of charged particles. This COMSOL Multiphysics model shows the path of B5+ ions passing through a focusing system of three magnetic quadrupoles. Each of the quadropoles focus the beam of ... Per saperne di più
A Helmholtz coil is a parallel pair of identical circular coils spaced one radius apart and wound so that the current flows through both coils in the same direction. This winding results in a uniform magnetic field between the coils with the primary component parallel to the axes of the ... Per saperne di più
This introduction model creates a simple model of the magnetostatics problem with a wire of infinite length carrying current, which is commonly found in textbooks. Since there is an analytical solution to this problem, the model can be used to compare theory with numerical results from ... Per saperne di più
An iron sphere in a magnetic field is an excellent textbook example to demonstrate the effects of a magnetic field interacting with a permeable material. This tutorial series is designed as an introduction to numerically modeling electromagnetic effects with COMSOL. This series ... Per saperne di più
When a conductive solid material moves through a static magnetic field, an eddy current is induced. The current that flows through the conductor, which is itself moving through the magnetic field, induces a Lorentz force back on the solid. Therefore, a conductive solid that is vibrating ...

The magnets in an Interior Permanent Magnet (IPM) motor are embedded in the rotor core, where they form narrow regions known as bridges. The thickness of the magnetic bridge is an important parameter to consider in design, both from the electromagnetic and the mechanical perspectives. As ... Per saperne di più
In this example, the coupling between Multibody Dynamics and Rotating Machinery, Magnetic for performing electromagnetic and mechanical analysis is demonstrated. A permanent magnet motor with 10 rotor poles and 12 stator slots is modelled in 2D. The magnets are attached to the ... Per saperne di più
Magnetotellurics is a method for estimating the resistivity profile of the Earth's subsurface using the natural electromagnetic source provided by the ionosphere. This model was defined by Zhdanov et al. in a study published in 1997. In this article, various scientific groups compared ... Per saperne di più
A vessel traveling on the surface or under water gives rise to detectable local disturbances in the Earth’s magnetic field. These disturbances can be used to trigger weapon systems. The magnetic signature of a ship can be reduced by generating a counteracting magnetic field of suitable ... Per saperne di più
