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.
Crimping is the plastic deformation process used to form an electrical joint between a stranded conductor and a terminal. The process involves complex multi-surface contact, including self-contact, as the terminal sleeve is plastically deformed around the wire strands. This example ... Per saperne di più
Oscillating chemical reactions were long thought to simply not exist in homogeneous solution, and even the poster child, the Belousov–Zhabotinsky reaction, met such an initial skepticism, that even though it was discovered in 1951, it took almost 20 years for it to gain widespread fame. ...

This model shows how to include the nonlinear (large signal) behavior of certain lumped components in a simplified loudspeaker analysis. The mechanical and electrical system is modeled using an equivalent electrical circuit. The large signal compliance CMS(x) and force factor BL(x) are ... Per saperne di più
The tonpilz (sound mushroom) piezoelectric transducer is a transducer for relatively low frequency, high power sound emission. The transducer consists of piezoceramic rings stacked between massive ends and pre-stressed by a central bolt. The tail and head mass lower the resonance ... Per saperne di più
An electrostatically actuated MEMS resonator is simulated in the time and frequency domains. The device is driven by an AC + DC bias voltage applied across a parallel plate capacitor. The dependence of the resonant frequency on DC bias is assessed, and frequency domain and transient ... Per saperne di più
Predicting the noise radiation from a dynamic system gives designers insight into the behavior of moving mechanisms early in the design process. For example, consider a gearbox in which the change in the gear mesh stiffness causes vibrations. These vibrations are transmitted to the ... Per saperne di più
An important step in brewing beer is the fermentation process. Here, alcohol is formed together with various flavor substances from sugars in the presence of yeast. The initial sugar content, temperature, and yeast type dictate how the fermentation proceeds. In this example, the ... Per saperne di più
In this example, the homogenized elastic and viscoelastic properties of a particulate composite are computed based on the individual properties of elastic particles embedded in a viscoelastic matrix. Periodic boundary conditions are applied to a unit cell of the particulate composite ... Per saperne di più
This tutorial models the thermal management of a polymer electrolyte membrane (PEM) fuel cell stack. Operating the stack with a similar temperature profile for all cells is important since an uneven temperature distribution may otherwise result in nonuniform water vapor condensation and ...

This is a full vibro-electroacoustic simulation of a balanced armature transducer (BAT also known as a receiver in some industries) which is a high performance miniature loudspeaker often used in hearing aids and other in-ear audio products. The model is set up using a linear frequency ... Per saperne di più
