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.
Small heating circuits find use in many applications. For example, in manufacturing processes, they heat up reactive fluids. The device in this tutorial consists of an electrically resistive layer deposited on a glass plate. The layer results in Joule heating when a voltage is applied to ... Per saperne di più
This tutorial model is of a micro perforated plate (also known as MPP) backed by a vibrating structure. This is a typical configuration in, for example, a MEMS microphone. The vibrating structure is not modeled explicitly, but just assigned a vibration velocity. The vibrating structure ... Per saperne di più
This model simulates the isotropic compression of naturally structured and artificially structured clays using the Modified Structured Cam-Clay (MSCC) material model. The aim of the example is to reproduce the compression behavior given in a benchmark for four structured clays. Per saperne di più
In this tutorial model, a step thrust bearing is topology optimized to maximize the bearing capacity. A step thrust bearing consists of a stepped bearing surface on which the end of the shaft rotates. The entire assembly is submerged in a lubricant. The shaft collar is assumed to be ...

In this example, the Bergstrom–Bischoff material model is used to model the temperature and strain dependent behavior of High Density Polyethylene (HDPE) used, for example, to make liners for damaged pipes in oil and gas applications, or to make type IV hydrogen storage vessels for fuel ...

This model demonstrates alternative implementations used for describing a thin layer and the impact of the choice on the continuity of the displacement and stress fields. It is shown how a perfect interface can be obtained by asymptotically changing the material parameters. Per saperne di più
Piezoelectric devices are widely used as sources to generate sound waves or receivers to detect acoustic signals. In applications such as ultrasound imaging and nondestructive testing, the same transducer can be used as a transmitter to send a source signal and receiver to detect ... Per saperne di più
When analyzing rotors, it is common that bearings are modeled through their effective dynamic coefficients about a static equilibrium position. This model illustrates how to compute such coefficients for a cylindrical journal bearing. The bearing length is kept much smaller than its ... Per saperne di più
This example models the behavior of soil during a tunnel excavation. The surface settlement and the width of the plastic region around the tunnel are important parameters needed to predict required reinforcements during the excavation. Two study steps are used. The first study computes ... Per saperne di più
Stents are used in biomedical applications to support the inner wall of veins and arteries. Self-expanding stents made of shape memory alloys work differently from balloon-inflated stents, as these stents are crimped to the artery diameter at low temperature then released while the blood ...
