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 evanescent mode cavity filter can be realized by adding a structure inside of the cavity. This structure changes the resonant frequency lower than the dominant mode of the unfilled cavity. A piezo actuator is used to control the size of a small air gap which provides the tunability of ... Per saperne di più
An important and interesting phenomenon with supersonic flows are expansion fans, which take place when the flow encounters a convex or expansion corner. The direction of the flow changes smoothly across the fan, while the Mach number increases. This 2D example models an expansion fan ... Per saperne di più
A plane wave is incident on a reflecting hexagonal grating. The grating cell consists of a protruding semisphere. The scattering coefficients for the different diffraction orders are calculated for a few different wavelengths. Per saperne di più
This example exemplifies how to model thermal curing using the base package of COMSOL Multiphysics. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Modeling the Thermal Curing Process". Per saperne di più
This example exemplifies how to model thermal phase change that is subject to hysteresis. A more detailed description of the phenomenon, and the modeling process, can be seen in the blog post "Thermal Modeling of Phase-Change Materials with Hysteresis" as well as: "How to Use State ...

Roller conveyors are commonly used in warehouses, manufacturing units and baggage handling applications to transport objects from one place to other by gravity, power, or manually. A typical roller conveyor consists of an array of moving rollers arranged either in a straight or curved ... Per saperne di più
This model demonstrates how to compute the acoustic properties of an acoustic liner with a grazing flow. The liner consists of eight resonators with thin slits. The background grazing flow is at Mach number 0.3. The sound pressure level above the liner is computed and can be compared to ... Per saperne di più
A 2D model of a steel bar is used to simulate oil quenching from an austenitic state. Both diffusive and displacive phase transformations are used, and the phase composition is computed in the radial direction of the bar. Per saperne di più
Laser systems are an important application area in modern electronics. With nonlinear materials it is possible to generate harmonics that are a multiple of the frequency of the laser light. This model shows how a second harmonic generation can be set up as a transient wave simulation, ... Per saperne di più
This app demonstrates: Light theme This app allows you to evaluate cross-section data for a wide range of American and European standard beams. Given a set of forces and moments acting on the section, you can also compute a detailed stress distribution. Calculated cross-section data ... Per saperne di più
