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.
An important and interesting phenomenon with supersonic flows are expansion fans, which take place when the flow encounters a convex or expansion corner. The direction of the flow changes smoothly across the fan, while the Mach number increases. This 2D example models an expansion fan ... Per saperne di più

In mode analysis it is usually the primary goal to find a propagation constant. This quantity is often, but not always, real valued; if the analysis involves some lossy part, such as a nonzero conductivity or an open boundary, the eigenvalue is complex. In such situations, the real and ... Per saperne di più
The multipole expansion is a powerful tool for analyzing electromagnetic waves scattered by small objects. In the expansion, the scattered field is represented as a superposition of the fields created by a finite set of point multipoles. Each point multipole is connected to a unique ... Per saperne di più
In this tutorial the geometry of an occluded ear-canal simulator is optimized to match the acoustic response of a given ear. The target data in this model stems from a simulation of an ear canal, but it can also be based on measurements, or a response specified by a standard. Per saperne di più
This is a simple yet powerful simulation app for designing a two-dimensional reflective metalens. This metalens consists of a array of glass nanopillars on a metal substrate. Initially, the app determines the optimal grating parameters for a specific wavelength and calculates the ... Per saperne di più
This example demonstrates how to apply the Uncertainty Quantification (UQ) Module in COMSOL Multiphysics to analyze the performance and reliability of a simple resistor. Small variations in material properties, geometry, and manufacturing processes can significantly impact the resistance ... Per saperne di più
This model shows one approach for obtaining a broadband impulse response by combining ray-tracing and finite element methods. The combination is done all within COMSOL® and uses idealized filters. In this example, the simulation results are further compared to an analytical solution ... Per saperne di più
Tutorial model that demonstrates how to work with COMSOL models in Excel, including loading and saving files, updating model parameters, solving, and retrieving results. Per saperne di più
This model simulates the shape evolution of a microconnector bump over time as copper deposits on an electrode surface. Transport of cupric ions in the electrolyte occurs by convection and diffusion. The electrode kinetics are described by a concentration dependent Butler-Volmer ... Per saperne di più
