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 example demonstrates how to set up a spatially varying dielectric distribution. Here, a convex lens shape is defined via a known deformation of a rectangular domain. The dielectric distribution is defined on the undeformed, original rectangular domain and is mapped onto the deformed ... Per saperne di più
The marine controlled source electromagnetics method (CSEM) for oil prospecting has emerged as a promising technique during recent years. This model demonstrates one variant of it. It uses a mobile horizontal 1 Hz electric dipole antenna that is towed 150 m above the sea floor. An array ... Per saperne di più
A tapered slot antenna, also known as a Vivaldi antenna, is useful for wide band applications. Here, an exponential function is used for the taper profile. The objective of this model is to compute the far-field pattern and to compute the impedance of the structure. Good matching is ... Per saperne di più
This model demonstrates how the Free Shape Boundary feature can be used to perform shape optimization on a design found with topology optimization. The model uses the same objective and constraint as the original, which results in a slightly higher stiffness for the same mass. Per saperne di più
This is an example of optimal control, where the input heating power to a rod is optimized to give a certain temperature on the outside of the rod. This is where the maximum water temperature occurs, while the minimum occurs at the center. Therefore this problem corresponds to the ... Per saperne di più
This model is an introduction to defining and verifying a satellite orbit, and computing the solar, albedo, and Earth infrared thermal loads. A 1U CubeSat is in a circular orbit at 400km altitude, inclination of 50°, and longitude of ascending node of 0°. The satellite is rotating slowly ... Per saperne di più
This tutorial demonstrates how to model the interaction between an acoustic field and the heat release from a flame, using the Flame Model domain feature. Modeling this interaction is important in order to understand and predict unstable acoustic modes in gas turbines and jet engines. ... Per saperne di più
With an increase in the parallel component of the applied field, carriers can gain energies above the ambient thermal energy and be able to transfer energy gained by the field to the lattice by optical phonon emission. The latter effect leads to a saturation of the carriers mobility. The ... Per saperne di più
This model demonstrates how to simulate a metasurface beam deflector that uses anomalous refraction. The structure itself is a repeated array of six posts (so-called meta elements). The periodicity of the individual posts is 500 nm, so the full structure of six posts is 3 um wide. The ... Per saperne di più
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
