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 tutorial simulates a standard test and benchmark model for perfectly matched layers (PMLs) as absorbing boundary conditions in the time domain. It involves the propagation of a transient Gaussian pulse with no flow. The Pressure Acoustics, Transient interface is used together with ... Per saperne di più
This model demonstrates how to simulate a piezoelectric transducer as both a sound transmitter and a receiver in a well logging setup. Other applications of this setup are, for example, in the field of nondestructive testing. A transmitting transducer is connected to an electrical ... Per saperne di più
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
This model is of the P.57 Type 4.3 Full-band Ear Simulator. The model includes the geometry of the ear canal as well as the pinna defined in the ITU-T P.57 standard. The model also includes interpolation data for an ear drum impedance ensuring correct acoustic properties of the ear. The ... Per saperne di più
This model analyzes a piezoelectric microelectromechanical system (MEMS) speaker. The speaker, composed of four triangular membranes, uses a layer of lead zirconate titanate (PZT) material with two electrodes on top of a silicon layer as actuators. The triangular membranes are separated ... Per saperne di più
Perforates are plates with a distribution of small perforations or holes. They are used in muffler systems, sound absorbing panels, and in many other places as liners, where it is important to control attenuation precisely. As the perforations become smaller and smaller, viscous and ... Per saperne di più
In this model, we use the Pressure Acoustics, Boundary Elements physics interface to analyze the acoustics of a generic head and torso simulator. This is a manikin head used to do standardized measurements for hearing aids, mobile phones, and headphones. The model showcases some ... Per saperne di più
This is the model of an occluded ear canal simulator (a generic 711 coupler). Besides certain details the geometry corresponds to the Brüel & Kjær Ear Simulator Type 4157. The real life couplers are used for simulating the acoustics of a standardized human ear canal and can be used ... Per saperne di più
In this 2D tutorial, a test sample consists on one side of an isotropic material and on the other side of a heterogeneous anisotropic material (a transverse anisotropic zinc crystal). Elastic waves in the sample are excited by a point-like force. The model is solved with the Elastic ... Per saperne di più
This tutorial showcases the principles of the immersion ultrasonic testing technique. A search unit placed in a water tank sends an ultrasonic pulse signal that scatters off a solid object. Part of the signal is reflected back to the search unit by the object and possible flaws in it. By ... Per saperne di più
