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 industrial-scale proof of concept (POC) model demonstrates how to perform an electric-thermal analysis of a high-power insulated-gate bipolar transistor module (IGBT module). The module has a rated voltage of 1200 V, and nominal current of 1800 A. Using a stationary study the ... Per saperne di più
In a polymer electrolyte membrane water electrolyzer cell, hydrogen and oxygen gas is produced by electrolysis. The hydrogen and oxygen compartments are separated by a polymer membrane, that also acts as electrolyte. This introductory tutorial computes the ohmic and activation losses in ... Per saperne di più
The purpose of this model is to introduce the specular reflection in Surface-to-Surface Radiation using the ray-shooting algorithm. Different parameters are available to the user to yield better accuracy in the results when using the ray-shooting algorithm. The model is a standard ... Per saperne di più
A gearbox is used to transfer power from an engine to its associated wheels or cogs, which can result in radiating noise to the surroundings. This is due to the transmission of undesired lateral and axial forces on the bearings and housing, while transmitting power from one shaft to the ... Per saperne di più
This tutorial uses a simple 1D model of a silicon solar cell to illustrate the basic steps to set up and perform a device physics simulation with the Semiconductor Module. A user-defined expression is used for the photo-generation rate and the result shows typical I–V and P–V curves of ... Per saperne di più
In this tutorial model, you will see how to set up an eigenfrequency analysis of a rotor with multiple disks and bearings. The example illustrates how to use Campbell and stability diagrams to identify the critical speeds and the stability threshold. The rotor is modeled using the Beam ... Per saperne di più
A square airbag made of a hyperelastic, compressible neo-Hookean material is inflated using pressurized air. Compressive stresses trigger wrinkling in some regions of the thin airbag. In this example, the wrinkling behavior is modeled using tension field theory, which gives a correct ... Per saperne di più
In the semiconductor industry, rapid thermal annealing (RTA) is a semiconductor process step used for the activation of dopants and the interfacial reaction of metal contacts. In principle, the operation involves rapid heating of a wafer from ambient to approximately 1000–1500 K. As soon ... Per saperne di più
Corrosion induced due to alternating current (AC) is evident in the oil and gas industry, particularly when a pipeline is in close proximity to the high power transmission lines. A numerical model presented here first evaluates the effect of direct current (DC) applied potential on ... Per saperne di più
This example was originally formulated by Albert Witarsa under Professor Bruce Finlayson’s supervision at the University of Washington in Seattle. It was part of a graduate course in which the assignment consisted of evaluating the potential of patents in the field of microfluidics ... Per saperne di più
