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.
These examples demonstrate how to compute the total reflection, transmission, and absorption of light when a plane wave, at optical wavelengths, is incident upon a dielectric slab with a thin metal coating. Three examples are included that show: An optically flat slab A slab with a ... Per saperne di più
The underlying physics of a capacitively coupled plasma is rather complicated, even for rather simple geometric configurations and plasma chemistries. This model benchmarks the Capacitively Coupled Plasma physics interface against many different codes. Per saperne di più
The multipole expansion is a powerful tool for analyzing electromagnetic waves scattered by small objects. In the expansion, the scattered field is represented as a superposition of the fields created by a finite set of point multipoles. Each point multipole is connected to a unique ... Per saperne di più
Roll forming processes are widely used in metal processing, battery electrode production and manufacturing processes. The model demonstrates the process of roll forming, where a workpiece is pressed after passing through a pair of rollers. The workpiece is carried between rollers by ... Per saperne di più
Streamers are transient filamentary electric discharges that can develop in a nonconducting background in the presence of an intense electric field. These discharges can attain high electron number density and consequently a high concentration of chemical active species that are relevant ... Per saperne di più
This tutorial drives a capacitively coupled plasma with an L-type matching network at high and low powers. At low power, where the harmonics in the current are low, prefect matching is obtained at the chosen power value. Sweeps over power, frequency, and pressure are performed and their ...

A waveguide-type structure can be fabricated on a substrate by adding vias between the microstrip line and the ground plane. Such a device will behave as a high-pass filter and is attractive because it is easy to fabricate. A model is set up that shows the S-parameters as a function of ... Per saperne di più
This example involves a static 2D axisymmetric analysis of a piezoelectric actuator using the Piezoelectric Devices physics interface. It models a radially polarized piezoelectric tube, as described by S. Peelamedu and co-authors. An application area where radially polarized tubes are ... Per saperne di più
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
This tutorial shows how to solve the full time-dependent wave equation in dispersive media such as plasmas and semiconductors. The 2D TM in-plane wave model solves for the vector potential from the wave equation and for an auxiliary electric polarization density from an ordinary ... Per saperne di più
