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 illustrates how to use a reduced order model to compute the response of a structure subjected to three simultaneous loads having independent time histories. Reduced order models provide an efficient way to analyze problems within linear structural dynamics. Per saperne di più
In this example, learn how to model two rotors connected by a spline coupling. The first rotor is a fixed cantilevered rotor and the second rotor is supported. The model assumes that only translational motion is coupled between the rotors through the coupling, while the rotations of both ... Per saperne di più
This example explores the shift in natural frequencies caused by changing the temperature. One study investigates a doubly clamped beam where both ends are fixed, while the other study looks at a cantilever beam where only one end is fixed. The following effects are studied: Stress ...

The stresses in a pulley connected to an engine that drives another pulley are studied in this model. A parametric analysis is conducted in order to study how the rotational speed affects the stress distribution in the pulley. The power at the pulley shaft remains constant, the moment ...

In this tutorial model, you will see how to set up an eigenfrequency analysis of a rotor with multiple disks and bearings. The example illustrates how to use Campbell and stability diagrams to identify the critical speeds and the stability threshold. The rotor is modeled using the Beam ... Per saperne di più
This example models heat generation in a beam-like structure subjected to small amplitude vibrations. The model computes the linear elastic response in the frequency domain. The transient heat-transfer analysis simulates the slow-rising temperature in the beam using the heat generated ... Per saperne di più
This tutorial model demonstrates the use of dynamic cyclic symmetry with postprocessing on the full geometry. A 3D impeller with eight identical blades can be divided into eight sectors of symmetry. The model computes the fundamental frequencies for the full impeller geometry and ... Per saperne di più
Vibration and noise in washing machines, due to the non-uniform distribution of clothes in the barrel, is a common problem worth studying and optimizing for. This model simulates a multibody dynamics model of a horizontal-axis portable washing machine. An eigenfrequency analysis is ... Per saperne di più
This model studies free and forced vibrations of a deep beam. The solution for eigenfrequency, frequency response and transient analysis are computed using a Timoshenko beam and compared with analytical results. Per saperne di più
