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 is a full vibro-electroacoustic simulation of a balanced armature transducer (BAT or also known as a receiver in some industries) which is a high-performance miniature loudspeaker often used in hearing aids and other in-ear audio products such as earbuds. The model is set up and ... Per saperne di più
At the resonance frequency, the capacitive coupling between the turns causes the impedance of a coil to transition from inductive to capacitive. This application analyzes the resonance of a 5 turn spiral coil of copper equipped with a thin epoxy varnish insulation layer. The capacitive ... Per saperne di più
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
Electromagnetic analysis of a 400kVA, 15kV/400V three-phase power transformer with Y-d connection and multiple primary and secondary coils with hundreds of turns. The model features the standard open- and short-circuit test in 2Daxi and 3D simulations to estimate electrical quantities ... Per saperne di più
This model presents the static field modeling of an outward flux focusing magnetic rotor using permanent magnets. This magnetic rotor is also often called a Halbach rotor. The use of permanent magnets in rotatory devices such as motors, generators and magnetic gears is increasing. The ... Per saperne di più
This example demonstrates how to use the Electrostatic interface to calculate the surface electric field of a typical high-voltage insulator. It is shown that the inhomogeneity and the maximum of the surface electric field are greatly reduced with the installation of the grading rings. ... Per saperne di più
This model presents two examples of topology optimization of the magnetic circuit of a loudspeaker driver. A first optimization is used to find the design of a nonlinear iron pole piece and top plate that maximize the BL factor at the resting position (small displacements), while ... Per saperne di più
In this model, a rotor with permanent magnets and a nonlinear magnetic material rotates within a stator of the same magnetic material. The generated voltage in windings around the stator is calculated as a function of time. COMSOL Multiphysics models the rotation with assemblies and ... Per saperne di più
In this model, we show how to model Seebeck effect which works as a thermoelectric generator. Seebeck effect is a phenomena where the difference in temperature of a material leads to a potential difference. The potential drawn in this model was compared with the paper by Jaegle (Example ...

Magnetostrictive transduction is used in sonars, acoustic devices, active vibration, and position control and fuel injection systems. The transducer has a steel housing enclosing a drive coil. A magnetostrictive material is placed in the core, which works as an actuator when a magnetic ... Per saperne di più
