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 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 model studies the transient response to an emitted Gaussian modulated harmonic signal solved with the Pressure Acoustics, Time Explicit physics ... Per saperne di più
A scanning electron microscope samples images by scanning a target with a high-energy beam of electrons. The subsequent electron interactions produce signals such as secondary and back-scattered electrons that contain information about the sample surface topography. Electromagnetic ...

This model computes the fluid flow, charge transport and electric potential in an electrostatic precipitator. Based on the resulting fields, particles of different diameter are fed into the device and the transmission probability is computed. As expected, the separation efficiency shows ...

When simulations are involved in the development of mobile devices, consumer electronics, hearing aids, or headsets, it is necessary to consider how the transducers interact with the rest of the system. Here, we show an analysis of the interaction between a vibration isolation mounting ... Per saperne di più
This tutorial performs steady-state and transient analysis of the response of a PIN diode to constant and pulsed radiation, respectively. The effect of radiation is modeled as spatially uniform generation of electron-hole pairs within the device. At high dose rates the separation of the ... Per saperne di più
This is a full vibro-electroacoustic simulation of a balanced armature transducer (BAT 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. The model is set up using a linear frequency ... Per saperne di più
Porous materials are frequently represented through periodically arranged microstructures. To compute porous media flow, the macroscale permeability and porosity is used which can be calculated from the creeping flow results through the microscale unit cell. In this application, various ... Per saperne di più
This example of turbulent flow in a partially baffled turbulent mixer with a three-bladed impeller shows how to set up the Rotating Machinery, Turbulent Flow interfaces from the Mixer Module with a Level Set method for free surface flow in a rotating geometry. A time-dependent simulation ... Per saperne di più
Squeeze film dampers are components that provide additional damping to rotating machines. To simplify the modeling of a rotor assembly, squeeze film dampers are modeled in terms of their damping coefficients which are a functions of the journal location in the damper. This model computes ... Per saperne di più
The first model describes the simultaneous flow of two immiscible fluids in porous media - here air displaces water in a multi-step inlet pressure experiment. We solve for the pressure and the degree saturation for the air and water within a representative volume and so track saturation ... Per saperne di più
