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.
An electrostatically actuated MEMS resonator is simulated in the time and frequency domains. The device is driven by an AC + DC bias voltage applied across a parallel plate capacitor. The dependence of the resonant frequency on DC bias is assessed, and frequency domain and pull-in ... Per saperne di più
Transmission lines are used when the frequency of the electromagnetic signals is so high that the wave nature of the signals must be taken into account. A consequence of the wave nature is that the signals are reflected if there are abrupt changes of the characteristic impedance along ... Per saperne di più
This is a primer model of a permanent magnet machine. It is a generic model that can be modified to simulate a motor or generator. It demonstrates different capabilities of COMSOL Multiphysics® to examine aspects of machine design, such as air gap magnetomotive force (MMF), ... Per saperne di più
This app demonstrates the following: Designing an app for small screens such as smartphones User-interface navigation with a top menu typically used on websites Geometry parts and parameterized geometries Visualizing periodicity of a geometry with material rendering Warning messages on ...

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
This single-phase induction motor model is used to compare with Testing Electromagnetic Analysis Method (TEAM) workshop problem 30. The Magnetic Fields physics interface is used to model the motor in the frequency domain at 60 Hz. The Velocity (Lorentz Term) feature is used to model the ... Per saperne di più
The model performs a static analysis on a piezoelectric actuator based on the movement of a cantilever beam, using the Piezoelectric Devices predefined multiphysics interface. Inspired by work done by V. Piefort and A. Benjeddou, it models a sandwich beam using the shear mode of the ... Per saperne di più
Many piezoelectric materials are ferroelectric. Ferroelectric materials exhibit nonlinear polarization behavior, such as hysteresis and saturation at large applied electric fields. In addition, the polarization and mechanical deformations in such materials can be strongly coupled due to ... Per saperne di più
Electromagnetic scattering simulation for an object with continuous rotational symmetry can be performed in 2D axisymmetry instead of 3D to drastically reduce computational time and resources. This model shows how to simulate arbitrary plane wave incidence in 2D axisymmetric models by ... Per saperne di più
This is a busbar configuration with an AC analysis. The configuration is similar to the introductory tutorial in the book Introduction to COMSOL Multiphysics. However, two conductors are added to represent a more realistic case of magnetic fields surrounding the busbar. The results ... Per saperne di più
