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.
The acoustic field in a model of an axially symmetric lined aero-engine duct, based on modal sound transmission, is analyzed. The source is generated by a single mode excitation at a boundary. Sources and nonreflecting conditions are applied using port boundary conditions. The model ... Per saperne di più
A double-ridged horn antenna is popularly used in anechoic chambers to characterize an antenna under test (AUT), from S-band to Ku-band, due to its reliable performance in a wideband frequency range. This tutorial models a double-ridged horn antenna and computes the voltage standing wave ... Per saperne di più
Magnetic resonance imaging (MRI) systems generate a magnetic flux density (B-field) to create images. Providing a homogeneous field distribution within a birdcage coil is a key factor for improving the quality of the scanned data. A homogeneous magnetic field can be found through ...

A capacitive micromachined ultrasonic transducer (CMUT) is a micro-scale receiver that converts ultrasound to electrical signal for high-resolution imaging application. This CMUT design has optimized force-displacement characteristics for increased transduction efficiency. Central to the ... Per saperne di più
The use of wave-based techniques for room acoustic simulations has spread in the last years due to the increase in computational performance as well as the development of new numerical methods. The challenge of including realistic impedance conditions at walls is traditionally solved in ... Per saperne di più
This tutorial shows the analysis of a car cabin in order to study the performance of a sound system in the low to mid frequency range. The cabin is of a typical sedan interior, that is, the inside of a hard-top family car. The model studies the frequency response at the location of a ... Per saperne di più
This model provides you with tools to build a variety of mixers by combining two common types of vessels with two types of impellers. The mixers are baffled flat and dished bottom vessels with either pitched blade impellers or Rushton turbines. The model includes three examples using the ... Per saperne di più
Knowing the velocity of a moving fluid is important in all cases where the fluid is used to transport material or energy. In the time-of-flight or transit-time method for determining flow velocity, an ultrasonic signal is transmitted across the main flow in a pipe to noninvasively ... Per saperne di più
Electrical events, such as an overcurrent or overload, can seriously damage electrical circuits or power lines. To avoid expensive replacements of critical parts, electric switch circuit breakers can be installed. These mechanically interrupt the current flow or surge by moving a plunger ... Per saperne di più
Large FEM simulations can be costly and, if repeated simulations are needed, it can be beneficial to use reduced-order models (ROMs). ROMs are typically valid only in the vicinity of their design conditions and have lower accuracy, but the simulation time is significantly shorter. The ... Per saperne di più
