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.
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, ...

This example consists of a 2D analysis of propagation modes in the chamber of a muffler. In this case, the muffler walls are considered to be made of a linear elastic material and account for their influence on the modes propagating through the cross section of the chamber. This analysis ... Per saperne di più
This model presents a practical and efficient method to compute the sound transmission loss (STL) through a building component, specifically this example treats the case of a concrete wall. The method used here is valid as long as the component has little influence on the acoustic field ... Per saperne di più
This model shows an application of the Acoustic Diffusion Equation physics interface. The acoustics in a two-story one-family house consisting of 10 rooms is analyzed. The steady state sound pressure level and energy density distributions are analyzed for a monopole source located in ... Per saperne di più
When designing a concert hall, it is extremely important to take the resonances into account. For a clear and neutral sound, the eigenfrequencies should be evenly spread through the registers. For the home stereo owner, who cannot actually change the shape of his living room, another ... Per saperne di più
This model analyzes the frequency response of a fuel tank partially filled with fluid. The tank is submitted to a vertical acceleration. Two modeling methods are considered to represent the fluid: a traditional method of smearing the mass of the fluid through the wetted surface of the ... Per saperne di più
Reflective mufflers are best suited for the low-frequency range where only plane waves can propagate in the system, while dissipative mufflers with fibers are efficient in the mid- to high-frequency range. Dissipative mufflers based on flow losses, on the other hand, also work at low ... Per saperne di più
Helmholtz resonators are used in exhaust systems, as they can attenuate a specific narrow frequency band. The presence of a flow in the system alters the acoustic properties of the resonator and the transmission loss of the subsystem. In this tutorial model, a Helmholtz resonator is ...

This model shows how shape optimization can be used to design an acoustic demultiplexer. A demultiplexer is a data distributing device, in this case it will distribute acoustic energy. The geometry consists of a circular domain with one input port and two output ports. The domain has the ... Per saperne di più
This example shows how to model a loudspeaker driver of the dynamic cone type, common for low and medium frequencies. The analysis is carried out in the frequency domain and thus represents the linear behavior of the driver. The model analysis includes the total electric impedance and ... Per saperne di più
