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 drift velocity of Ar+ is calculated using a Monte Carlo simulation in which the elastic collisions of Argon ions with ambient neutrals are explicitly modeled. The model uses energy-dependent collision cross-section data from experiment. The average ion velocity values are consistent ... Per saperne di più
Modeling the electrical activity in cardiac tissue is an important step in understanding the patterns of contractions and dilations in the heart. The heart produces rhythmic electrical pulses, which trigger the mechanical contractions of the muscle. A number of heart conditions involve ... Per saperne di più
Crystallization is an important separation process in the chemical industry. It is used for the production of pharmaceuticals and industrial chemicals. It can also be used in resource recovery as a way of separating valuable materials from waste. This model solves a discretized ... 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
This model illustrates the use of COMSOL Multiphysics for modeling of ionic current distribution problems in electrolytes, in this case in human tissue. The problem is exemplified on a pacemaker electrode, but it can be applied in electrochemical cells like fuel cells, batteries, ... Per saperne di più
The problem of a plane wave scattering off a cylinder-shaped object suggests the use of the 2D axisymmetric formulation. This can save computation time and reduce the memory usage compared to the model in 3D space. This example demonstrates the use of the built-in plane wave expansion ... Per saperne di più
Removing halogen groups from hydrocarbons is an important reaction step in several chemical processes. One application is water purification. Other examples involve organic synthesis, where the removal of halogen groups serves as a starting point for carbon-carbon coupling reactions. ... Per saperne di più
This model analyzes the operation of a micromirror in air and the effects of thermoviscous damping on the vibration response. The model includes thermal losses in the structure as well as thermoviscous acoustic phenomena. The model couples the Thermoelasticity multiphysics interface to ... Per saperne di più
This model shows how to perform a submodeling analysis in order to evaluate structural stress. Using a submodel helps to compute the results in a refined geometry detail while applying loads and constraints in the global model. 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
