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.
A waveguide filter is designed using shape optimization by moving and scaling rectangles in the geometry. The irises of the initial geometry are optimized to ensure good bandpass response and out-of-band rejection, while maintaining the double mirror symmetry. The EGO optimization solver ...

This example of a plasmonic waveguide filter shows that the waveguide rejects the electromagnetic radiation of the wavelength between 1.4 um and 1.6 um, but allows the rest of the wavelength. The silver material can be modeled using the Drude-Lorentz approximation, with ε∞ = 3.7, ωp = 13 ... Per saperne di più
Creating irregular geometries can be a good solution, even the only option, for some types of applications. These files present a way to use a text file with material properties defined in coordinates to assign different materials even though there is only one regular domain. The same ...

This model demonstrates two ways of modeling waveguides that support multiple modes. A PML can be used to absorb any modes, or Ports can be explicitly added for each possible mode. Learn more in this accompanying blog post: Modeling Waveguides that Support Multiple Modes Per saperne di più
This model describes a pencil beam scanning (PBS) magnet system for use in medical proton therapy. Simulations of the magnetic flux density and particle tracing are performed. Such models are useful for the design of PBS systems, particular with the advent of MR-integrated proton ... Per saperne di più
In food industries, microwave heating is gaining attention over a conventional heating treatment because of several advantages such as precise process control, speed of heating, fast turn-on and turn-off time, etc. In this model, a high directional Yagi-Uda antenna is used to heat up ...

This model simulates a holographic page data storage system. The studies include the recording and retrieval processes. The object beam encrypting 8-bit data is focused into a holographic material by a Fourier lens (Fourier transformation). In the recording process, the object beam ... 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
In this model, the transmitter (microstrip patch) and receiver (Yagi–Uda) antennas are modeled simultaneously in the FEM domain and are coupled with FEM–BEM coupling. The results are compared with the analytical Friis transmission formula. In detail, the emw and emw2 interfaces find out ... Per saperne di più
This model demonstrates a technique for partitioning a mesh based upon the element type. By first meshing with a boundary layer and then partitioning and creating a new mesh, it is possible to avoid modeling the interior volume of inductively heated parts, where the skin depth is small ...
