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.
Silicon micromechanical resonators have long been used for designing sensors and are now becoming increasingly important as oscillators in the consumer electronics market. In this series of models, a surface micromachined MEMS resonator, designed as part of a micromechanical filter, is ... Per saperne di più
This example shows how to model a load which varies in space and time. A series of load pulses travel along a beam which is supported at equal distances. For some combinations of the traveling speed of the load pulses and the spacing between them, it is possible to excite resonances in ... Per saperne di più
This model analyzes the frequency response of a fuel tank partially filled with fluid. The tank is submitted to a vertical acceleration. Two modeling methods are considered to represent the fluid: a traditional method of smearing the mass of the fluid through the wetted surface of the ... Per saperne di più
The mass of an aluminum beam is minimized subject to a displacement constraint and a distributed load. The problem is solved using parameter, shape and topology optimization. Per saperne di più
Failure of reinforced concrete structures involves advanced material behavior and interaction between materials. This example demonstrates how to model various stages of the failure of a reinforced concrete beam. The material model includes a coupled damage-plasticity model for the ... Per saperne di più
In these tutorial series, we demonstrate how to use the Offset Faces and Transform Faces operations as a way to reparameterize existing holes in a bracket geometry imported from a STEP file. The mass of the bracket is minimized with limits for both the lowest natural frequency, and for ... Per saperne di più
This example demonstrates how to use the Uncertainty Quantification Module by running a series of uncertainty quantification studies for a steel bracket. This type of bracket can be used to install an actuator that is mounted on a pin placed between the two holes in the bracket arms. ... Per saperne di più
For slender structures, buckling is a catastrophic instability if the service load is above the critical limit. For such structures, it can be important to study the behavior of the structure beyond the critical buckling load, which is known as postbuckling analysis. Tracing the ... Per saperne di più
This model demonstrates how to use the Polynomial Shell feature to increase the lowest Eigenfrequency of a shell by deforming its shape. Per saperne di più
Shape optimization with respect to fatigue properties is not supported, but fatigue properties are well correlated with the maximum stress. The model demonstrates how optimization with respect to a p-norm of the von Mises stress can be used to improve fatigue properties without ... Per saperne di più
