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 exemplifies how to compute the internal temperature distribution in a prismatic battery during a high-rate charge. The electrochemistry is described by a a lumped two-electrode model, which is coupled to the heat transfer model. The heat transfer model includes the effects of ... Per saperne di più
This tutorial model shows how to import data from an ODB++® archive to generate a geometry of a printed circuit board (PCB). Follow the instructions to learn how to remove small details from the geometry, create a mesh, and use automatically generated selections to define physics and ... Per saperne di più
During an internal short circuit of a battery, the two electrode materials are internally and electronically interconnected, giving rise to high local current densities. Internal short circuits may occur in a lithium-ion battery due to, for instance, lithium dendrite formation or a ... 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 entry is a compilation of some examples from DIN EN 1991-1-2 (Actions on structures exposed to fire). Models that are included: 1. Cooling (HT) 2. Heating (HT) 3. Heat transfer through multiple layers (HT) 4. Thermal elongation (SME, thermal stress) 5. Thermal expansion (SME, HT, ... Per saperne di più
This version of the balloon inflation example demonstrates how the Shell and Membrane interfaces can be used to model thin structures made of hyperelastic materials. The example is identical to the Model Library model 'Inflation of a spherical rubber balloon', except that the Membrane ... Per saperne di più
When simulations are involved in the development of mobile devices, consumer electronics, hearing aids, or headsets, it is necessary to consider how the transducers interact with the rest of the system. Here, we show an analysis of the interaction between a vibration isolation mounting ... Per saperne di più
Due to the large differences in length scales in a lithium-ion battery, with the thickness of the different layers typically being several orders of magnitude smaller than the extension in the sheet direction, a lithium-ion battery is often well represented by a one-dimensional model. ...

An eigenfrequency study is used to find the resonance frequency and threshold gain for an oxide-confined, GaAs-based, vertical-cavity surface-emitting laser (VCSEL). The simulations are performed in two steps. A regular eigenfrequency analysis is first performed, to find good initial ... Per saperne di più
This simple benchmark model computes the potential and carrier concentrations for a one-dimensional p-n junction using both the finite element and finite volume methods. The results are compared with an equivalent device from the book, "Semiconductor Devices: A Simulation Approach," by ... Per saperne di più
