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 studies a small orifice located in a duct. The transmission and reflection coefficients of the system are computed in the presence of a bias flow using the linearized Navier-Stokes equations. For certain frequencies the transmission coefficient shows amplification (T>1). This ... Per saperne di più
When a droplet is placed on a substrate on which surface acoustic waves (SAWs) are traveling, the energy of the SAWs is transferred into the droplet to form an acoustic field. The transferred energy is attenuated and generates a streaming flow. This type of streaming enables contactless ... Per saperne di più
Analyzing resonances is essential when designing loudspeakers. Resonances can come from various sources in a loudspeaker, with the diaphragm being a significant one. There are numerous traditional approaches to address diaphragm resonances, each with its own benefits and drawbacks. A ... Per saperne di più

For models with acoustic-structure couplings it is necessary to calculate the left eigenvectors to use the Frequency Domain, Modal solver. The model shows the necessary changes to the default settings of the eigenfrequency solver. Per saperne di più
This tutorial computes the transfer matrix of a tube and coupler measurement test setup. This type of setup is used for standardized testing, for example, for miniature loudspeakers or hearing aids. The Port boundary condition in Pressure Acoustics, Frequency Domain is used together ... Per saperne di più
This small tutorial model studies energy conservation in a small conceptual test setup. The model has an inlet and outlet (modeled using ports) and a Helmholtz resonator with a very narrow neck. The acoustics in the narrow neck are modeled with Thermoviscous Acoustic for a detailed ... Per saperne di più
This is a conceptual model of a microphone placed in an infinite baffle (flush mounted). The purpose is to determine the free-field level correction curve of the setup, which includes the exterior domain, microphone grid, and volume between the grid and the diaphragm. The microphone ...

These models introduce how to perform convolution via the convolution integral, discrete convolution, and convolution theorem. Specifically, they show how to implement convolution by applying these methods to the low-pass filtering of a room impulse response (IR) and the auralization of ... Per saperne di più
