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.
The backward facing step is an interesting case for studying the performance and solution strategy of a turbulence model. In this case, the flow is subjected to a sudden increase of cross-sectional area, resulting in a separation of flow starting at the point of expansion. Spatial ... Per saperne di più
It is more difficult to generate laser emissions in the short-wavelength part of the visible and near visible part of the electromagnetic spectrum than in the long-wavelength part. Nonlinear frequency mixing makes it easier to generate new short wavelengths from existing laser ... Per saperne di più
Modern cars have rear-windshield FM antennas to play FM radio. The radiation emitted from an antenna induces an electric current on the outer surface of any cable harnesses in the car, which can have negative effects. This model uses the RF Module to compute the far-field radiation ... Per saperne di più
An important step in brewing beer is the fermentation process. Here, alcohol is formed together with various flavor substances from sugars in the presence of yeast. The initial sugar content, temperature, and yeast type dictate how the fermentation proceeds. In this example, the ... Per saperne di più
This model is a benchmark problem from TEAM workshop (problem 15 part I, see https://www.compumag.org/wp/team/). The model simulates the behavior of a coil as it scans a conductive plate containing a defect (a crack). The computed coil parameters, which include change in resistance and ... Per saperne di più
This model demonstrates an integrated structural-thermal-optical performance (STOP) analysis of an optical system. The Petzval Lens tutoral is used as the basis for this model, together with a simple barrel geometry The isothermal model performs a Parametric Sweep over several uniform ... Per saperne di più
This model simulates an LED that emits in the infrared part of the electromagnetic spectrum. The device structure is made up of a single p-n junction formed by a layer of p-type doping near the top surface of an otherwise n-type wafer. This kind of device geometry is simple and cheap to ...

Consider an infinitely long steel cylinder resting on a flat aluminum foundation, where both structures are elastic. The cylinder is subjected to a point load along its top. The objective of this study is to find the contact pressure distribution and the length of contact between the ... Per saperne di più
This example demonstrates how to couple the Lithium-ion Battery interface to the Phase Field interface for modeling electrode deformations. The example is based on the Lithium Plating with Deformation model, available in the Battery Design Module Application Library. As current is ... Per saperne di più
This example studies the natural frequencies of a pretensioned membrane exhibiting stress stiffening. The model results are compared with the analytical solution. Two different techniques for generating the prestress are explored. Per saperne di più
