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 model simulates a temperature profile in a number of cells and cooling fins in a liquid-cooled battery pack. The model solves in 3D and for an operational point during a load cycle. A full 1D electrochemical model for the lithium battery calculates the average heat source. Per saperne di più
This example studies a portion of the vascular system of a young child. The aorta and its ramified blood vessels are embedded in biological tissue. The pressure from the moving fluid deforms the blood vessel. The complete analysis consists of two distinct but coupled procedures: a fluid ... Per saperne di più
Inductors are used in many applications for low pass filtering or for impedance matching of predominantly capacitive loads. They are used in a wide frequency range from near static up to several MHz. An inductor usually has a magnetic core to increase the inductance, while keeping its ... Per saperne di più
This is a model of the heating process in a microwave oven. The distributed heat source is computed in a stationary, frequency-domain electromagnetic analysis. This is followed by a transient heat transfer simulation showing how the heat redistributes in the food. Per saperne di più
This example simulates 3D unsteady laminar flow past a cylinder in a channel. The inflow velocity profile is time-varying. The lift and drag coefficients are computed, and results show good agreement with those published in the literature. Per saperne di più
This simple model demonstrates how to use the Semiconductor Optoelectronics interfaces to model a simple GaAs PIN diode structure. Both the stimulated and spontaneous emission in the semiconductor are accounted for. The corresponding absorption of the light and the associated change in ... Per saperne di più
This tutorial explores the current distribution in a low-temperature PEMFC when using serpentine-based flow field patterns. The cell is operated in counter-flow mode so that the oxygen and hydrogen inlet flow streams are located at opposite sides. Relatively dry inlet gas compositions ... Per saperne di più
When a tuning fork is struck, it vibrates in a complex motion pattern that can be described mathematically as the superposition of resonant modes, also known as eigenmodes. Each mode is associated with a particular eigenfrequency. The tuning fork produces its characteristic sound from ... Per saperne di più
The thermal stress in a layered plate is studied in this example. A plate consisting of two layers, a coating and a substrate layer, is stress and strain free at 800 degrees C. The temperature of the plate is reduced to 150 degrees C and thermal stresses are induced due to the difference ... Per saperne di più
This model provides you with tools to build a variety of mixers by combining two common types of vessels with two types of impellers. The mixers are baffled flat and dished bottom vessels with either pitched blade impellers or Rushton turbines. The model includes three examples using the ... Per saperne di più
