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.
These models are featured in the blog post Analyze Violin Tone and Volume with Multiphysics Modeling. One applies acoustic-structure interaction to study how the air mode resonance is affected by the coupled vibrations in the violin body. The other uses a potential flow approximation to ...

Ultrahigh Molecular Weight (UHMW) Polyethylene is a material commonly employed in knee and hip joint replacements. The “small punch test” is designed to assess mechanical properties using very small samples, such that because of their size they can directly be explanted. This example ... Per saperne di più
An automotive midwoofer is modeled using the lumped parameter approach. The electrical and mechanical components are modeled using a lumped electric circuit, which is coupled to a finite element model for the acoustics using the Lumped Speaker Boundary feature. The large signal ... Per saperne di più
Bearing clearances should be kept minimum to avoid non-synchronous vibration of a rotor. However, a tight clearance reduces the durability of the bearing. This example illustrates modeling of the vibration induced by nonlinear contact for different radial clearances. It is shown that ... Per saperne di più
These models illustrate some important topics when modeling buckling imperfection. The Euler 2 Buckling Imperfection model shows a simple case with a cantilever beam buckling under compression. Three different buckling modes are combined as initial imperfections. The other model, ... Per saperne di più
A load carrying component of a structure is subjected to multi-axial cyclic loading during which localized yielding of the material occurs. In this model you perform a low cycle fatigue analysis of the part based on the Smith-Watson-Topper (SWT) model. Due to localized yielding, you ... Per saperne di più
The small strain overlay material model captures the effect of high stiffness at low strain as well as the hysteresis under cyclic loading, which is a common effect for most soils. The formulation allows stiffness degradation with an increase in shear strain, and the full recovery of ... Per saperne di più
Lattice materials enable the creation of advanced additive manufacturing materials with customized mechanical properties. At the macroscopic level, these heterogeneous materials can be modeled as homogeneous materials. Homogenization techniques can accurately determine the material's ... Per saperne di più
In this example, the dynamics of a hopping hoop is simulated. A rigid rolling ring with a point mass on the perimeter can, under certain conditions, jump up from the surface on which it is rolling. The effects of different parameters like initial velocity and friction are explored. You ... Per saperne di più
This application illustrates a modeling approach for deriving physically consistent simplified models in the Acoustics Module. The approach consists of converting complex sub-components to an impedance boundary condition and otherwise using simple acoustics throughout the COMSOL model. ... Per saperne di più
