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 example demonstrates the use of the Solid-Beam Connection multiphysics coupling to create transitions between the Solid Mechanics and Beam interfaces. Two different connection types are discussed, and a comparison of the stress distributions at the transition is made. Per saperne di più
Using a Fluid-Solid Interaction multiphysics interface, the behavior of a spring-loaded ball check valve is studied under varying functional and reverse flow. The fluid force acting on the ball opens the valve at the opening pressure. In the case of a reversed pressure, the ball comes ... Per saperne di più
In a reciprocating piston engine the connecting rods transfer rotating motion into reciprocating motion. The connecting rods are constantly under high stresses and the load increases with the engine speed. A failure of one part in the engine usually results in a replacement of the whole ...

A circular metal bar is subjected to uniaxial tension. As an effect, large plastic strains develop. The material is elastoplastic with nonlinear isotropic hardening. As the elongation is increased, the decrease in radius becomes strongly nonuniform, so called "necking". The development ... Per saperne di più
This example shows how to model prestressed bolts. The bolt geometry is taken from the Part Libraries. For comparison, one of the bolts is modeled using a thread contact formulation, whereas the other bolt is connected to the bolt hole by a pure continuity condition. The reduced ... Per saperne di più
A tweeter is a high frequency driver used in loudspeaker systems. An ideal tweeter will produce a constant sound pressure level at a given distance in front of the driver independently of frequency, that is, a flat response. Ideally the tweeter will also, to a certain degree, maintain ... Per saperne di più
This app demonstrates the following: Using a Java® utility class for combining several waveforms and for playing sound Using tables for presenting results The app allows you to study the design of an organ pipe and then play the sound and pitch of the changed design. The pipe sound ... Per saperne di più
The drive for miniaturizing electronic devices has resulted in today’s extensive use of surface-mount electronic components. An important aspect in electronics design and the choice of materials is a product’s durability and lifetime. For surface-mount resistors and other components ... Per saperne di più
Including circumferential displacements in a 2D axisymmetric Solid Mechanics interface allows to compute twist and bending deformations. This model determines stress concentration factors for a hollow shaft for load cases of axial extension, torsion, as well as bending, using a ... Per saperne di più
The primary defense of a submarine lies in its capacity to remain hidden during operation. As radio waves are strongly absorbed by sea water, sound navigation ranging, or SONAR, is one of the main methods used for the detection of submarines. SONAR systems are also used for underwater ...
