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 electrodynamic ion funnel provides an efficient means of transferring ions from regions of high pressure to high vacuum. The ion funnel can couple devices which generally operate at pressures of different orders of magnitude, such as ion mobility spectrometers and mass spectrometers, ... Per saperne di più
This benchmark model simulates three different heterojunction configurations under forward and reverse bias. It shows the difference in using the continuous quasi-Fermi level formulation versus the thermionic emission formulation for the charge transfer across the heterojunction. The ... Per saperne di più
This example simulates Trichel pulses produced by negative corona discharge under a point-to-plate configuration. The electron density and the electric field are obtained, as well as the discharge current. The discharge current clearly shows the pulsating characters. Each current pulse ... Per saperne di più
Inductive devices experience capacitative coupling between conductors at high frequencies. Modeling this phenomenon requires that you describe electric fields that have components both parallel with and perpendicular to the wire. This consideration might lead to the conclusion that a 3D ... Per saperne di più
The goal with this app is to explain experimental electrochemical impedance spectroscopy (EIS) measurements and to show how you can use a simulation app, along with measurements, to estimate the properties of lithium-ion batteries. The app takes measurements from an EIS experiment and ... Per saperne di più
This model presents a 2D axisymmetric dipolar microwave plasma source sustained through resonant heating of the electrons. This is known as electron cyclotron resonance (ECR), which occurs when a suitable high magnetic flux density is present along with the microwaves. This is an ... Per saperne di più
Usually limited to a specific region, corona discharges appear as a consistent luminosity. The attributes of steady glow corona discharges change depending on their polarity. Positive glow corona, also referred to as Hermstein's glow or ultra corona, presents a direct current (DC) aspect ... Per saperne di più
This model computes the lightning-induced voltage on an overhead line positioned above a lossy ground. It includes parameters like the inclination angle of lightning channels and soil conductivity, enabling straightforward analysis of their impacts. The calculated induced voltage aligns ...

This tutorial uses a “black-box” approach to define a battery model based on a small set of lumped parameters, assuming no knowledge of the internal structure or design of the battery electrodes, or choice of materials. The input to the model is the battery capacity, the initial state ... Per saperne di più
Atmospheric corrosion occurs when metallic structures are exposed to humid air forming a thin electrolyte film in the range of up to a few hundred micrometers. The model presented here accounts for charge transport as well mass transport involving 10 species and 6 homogeneous ... Per saperne di più
