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 Gaussian electromagnetic wave is incident on a dense array of very thin wires (or rods). The distance between the rods and, thus, the rod diameter is much smaller than the wavelength. Under these circumstances, the rod array does not function as a diffraction grating (see the Plasmonic ... Per saperne di più
UHF RFID tags are widely used for identifying and tracking animals. This model simulates a passive radio-frequency identification (RFID) tag for the UHF frequency range. With respect to the chip transponder’s complex impedance, a reflection coefficient is computed. This is done using an ... Per saperne di più
A thin-walled frame with a central cutout is subjected to a random load. Although the stresses are far below the yield level of the material, damage accumulates over the load history. The Rainflow counting algorithm is used to define the load scenario and Palmgren-Miner linear damage ... Per saperne di più
Induction heating is used for various metallurgical processes such as hardening. Here the 3D induction heating of a mechanical joint passing through an induction heating coil is simulated. Curie point effects and temperature dependent resistivity in the iron are taken into account. To ... Per saperne di più
Periodic microstructures are frequently found in composite materials, metallic foams, and sandwich structures. They can be described by a unit cell repeated along the three Cartesian directions. This app computes homogenized material properties of various periodic microstructures and ... Per saperne di più
This tutorial model demonstrates how to set up a parameter estimation study for fitting the material parameters of an Ogden hyperelastic model to experimental data. The procedure considers multiple load cases under large deformations, which is often necessary to obtain constitutive ... Per saperne di più
Conical antennas are useful for many applications due to their broadband characteristics and relative simplicity. In this example, we study the antenna impedance and radiation pattern as functions of frequency for a monoconical antenna with a finite ground plane and a 50 ohm coaxial ... Per saperne di più
This model presents a practical and efficient method to compute the sound transmission loss (STL) through a building component. Specifically, this example treats the case of a double-glazed window. The method used here is valid for structural components that have a small influence on ... Per saperne di più
This example is an established benchmark case for the shallow water equations that models a 1/400 scaled laboratory experiment of the tsunami runup in Monai Valley in Japan. The experiment was made at the Central Research Institute for Electric Power Industry (CRIEIPI) in Abiko, Japan, ... Per saperne di più
Laminated composite shells made of carbon fiber reinforced polymer (CFRP) are common in a large variety of applications due to their high strength-to-weight ratio. Evaluation of the structural integrity of a laminated composite shell for a set of applied loads is necessary to make the ... Per saperne di più
