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 the propagation of a positive streamer in a weak electric field where the process of photoionization is essential to provide seed electrons at the front of the streamer head. The simulated electric field and electron density as a function of time agree well with that ... Per saperne di più
This model simulates convective heat transfer in a channel filled with water. To reduce memory requirements, the model is solved repeatedly on a pseudo-periodic section of the channel. Each solution corresponds to a different section, and before each solution step the temperature at the ... Per saperne di più
Commercial heat exchangers often feature a complex design. It is significantly easier to build a design with new CAD parameters than to build designs with novel topologies. This model demonstrate how to optimize the size and position of the tubes in a tube and shell heat exchanger. It is ... Per saperne di più
This tutorial demonstrates how to model ultrasound imaging in human tissue using an imaging probe composed of piezoelectric arrays that generate steered and focused beams. Simulating this process requires a transient multiphysics model to accurately capture sound generation, propagation, ... Per saperne di più
This model demonstrates how to set up a dynamic simulation that includes several contact interactions, including friction, using a single general contact pair. The dynamics is solved using explicit time stepping. Per saperne di più
This example shows how to model carbonation, which is a type of sparging. Sparging is a mass transfer process between a gas and a liquid that is common in industry (such as beverage carbonation and photobioreactor applications) and at home (aquarium aeration). In the carbonation model, ... Per saperne di più
This model uses the Semiconductor and RF modules to describe a photoconductive antenna (PCA). A laser pulse is applied on the surface of undoped LT-GaAs to generate electron-hole-pairs, which move under the influence of an external E-field creating a transient electric current pulse. ...

This model demonstrates how to set up a phase field damage multiphysics model to predict crack propagation in thermoelastic solids under large deformations. The crack-driving force depends on the principal stresses, which in turn depend on the temperature distribution in the solid ... Per saperne di più
Combinations of optical devices such as polarizers and wave retarders can be used to control the intensity and polarization of transmitted radiation. In this tutorial, two linear polarizers with orthogonal transmission axes are used to reduce the intensity of a ray to zero. Then the ... Per saperne di più
A demultiplexer is a device that directs different frequency bands to different outputs. In this tutorial model, we will design a demultiplexer by performing shape optimization on all initial circular boundaries in a sonic crystal (phononic crystal) configuration. The model uses shape ... Per saperne di più
