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 analyzes the electromagnetic, mechanical, and acoustical characteristics of the OWS-1943T-8CP (discontinued) speaker. Beside certain details, the geometry, material properties, and measurements are copyright by Ole Wolff. Starting from the geometry of the speaker, an ... Per saperne di più
In this model, the acoustics of the Small Hall in the Konzerthaus Berlin is simulated with ray tracing. A full study of the room is performed in 1/3-octave bands with 10 pairs of source-receiver positions. The room acoustic parameters are derived from the calculated impulse responses, ...

In this tutorial, the acoustic properties of a wax guard are analyzed. A wax guard is a small perforated mesh used to protect the receiver (the miniature loudspeaker in a hearing aid) used for receiver-in-the-ear (RITE) or receiver-in-canal (RIC) hearing aids. Because of the very small ... Per saperne di più
Small heating circuits find use in many applications. For example, in manufacturing processes, they heat up reactive fluids. The device in this tutorial example consists of an electrically resistive layer deposited on a glass plate. The layer results in Joule heating when a voltage is ... Per saperne di più
This is a full vibro-electroacoustic simulation of a balanced armature transducer (BAT or also known as a receiver in some industries) which is a high-performance miniature loudspeaker often used in hearing aids and other in-ear audio products such as earbuds. The model is set up and ... Per saperne di più
Different types of elements can be used for modeling a rotor, depending on the level of complexity and the type of the system being modeled. The modeling steps and representation of the results will vary with the type of idealization. In this tutorial model, an eigenfrequency analysis is ... Per saperne di più
Headphones are closely coupled to the ear, and so it is not possible to measure their sensitivity in a classical acoustic free-field setup used for loudspeakers. The measurement requires the use of artificial heads and ears to accurately represent the usage conditions. This model shows ... Per saperne di più
This tutorial model analyzes the propagation of seismic waves through Earth's internal structure. The model uses a 2D axisymmetric geometry to represent the material discontinuities and the variation of properties through the concentric layers of the earth. A simplified earthquake ...

Planar photonic waveguides in silica (SiO2) have great potential for use in wavelength routing applications. The major problem with this type of waveguide is birefringence. Anisotropic refractive indices result in fundamental mode splitting and pulse broadening. The goal is to minimize ... Per saperne di più
Electronic equipment often has to be certified to function after having been subjected to a specified shock load. In this example, the effect of an 50g 11ms half sine shock on a circuit board is investigated using response spectrum analysis. The results are compared with a time domain ... Per saperne di più
