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 series demonstrates three different approaches to remove small geometric entities from an imported 3D CAD geometry of a wheel rim: the Repair operation, the Defeaturing tools, and the Remove Details operation. Use Repair to automatically find and remove small entities ... Per saperne di più
The topology optimized Tesla microvalve is used as inspiration for a parametrized geometry. The optimization of this geometry takes erosion and dilation of the geometry into account by optimizing over a parametric sweep. In this example the optimization is driven by the worst of the 3 ...

A classical flow pattern is the von Kármán vortex street that can form as fluid flows past an object. These vortices may induce vibrations in the object. This problem involves a fluid-structure interaction where the large deformation affect the flow path. The magnitude and the ... Per saperne di più
This tutorial example of a comb drive tuning fork gyroscope is kindly provided by Dr. James Ransley at Veryst Engineering, LLC. The model demonstrates fully parameterized geometry, extensive use of selection features, implementation of analytic formulas for the electromechanical forces ... 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
The vibration modes of a thin or thick circular disc are well known, and it is possible to compute the corresponding eigenfrequencies to arbitrary precision from a series solution. The same is true for the acoustic modes of an air-filled cylinder with perfectly rigid walls. A more ... Per saperne di più
Liquid-solid mixtures (suspensions) are important in a variety of industrial fields, such as oil and gas refinement, paper manufacturing, food processing, slurry transport, and wastewater treatment. Several different modeling approaches have been developed by the CFD community, ranging ... Per saperne di più
A strong permanent magnet is placed close to a clamped thin plate made of iron. The magnetic force causes the plate to be deflected. This example studies the plate's elastic deformation and stress. The deformation of the plate has an influence on the distribution of the magnetic field. ... Per saperne di più
An evanescent mode cavity filter can be realized by adding a structure inside of the cavity. This structure changes the resonant frequency lower than the dominant mode of the unfilled cavity. A piezo actuator is used to control the size of a small air gap which provides the tunability of ... Per saperne di più
This model demonstrates 3D topology and shape optimization for an extruded geometry. This can be achieved using equation-based modeling and extrusion operators. The model considers stiffness maximization of a beam subject to a constraint on the mass, but the method can be used with any ... Per saperne di più
