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.
We present the results from a comparison of the level set, phase field, and moving mesh methods for modeling free liquid surfaces in the COMSOL Multiphysics® software. The comparison is carried out using an example problem. The example studies the formation of surface waves ... Per saperne di più
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 example, a torque is applied to the inner edge of a circular annulus-shaped membrane while the outer edge is fixed, resulting in membrane wrinkling. The wrinkling membrane model avoids the equilibrium instability that would be produced by the compressive stresses. The effect of ... Per saperne di più
This model investigates the electrical and thermal characteristics of an inductively coupled plasma torch at atmospheric pressure. The discharge is assumed to be in local thermodynamic equilibrium. Per saperne di più
Pitting corrosion is a type of localized corrosion by which local cavities, pits, are formed on an initially smooth metal surface. A pit may be initialized by surface defects, such as an inhomogeneities in composition or shape, or mechanical abuse resulting in a small scratch or dent. ... Per saperne di più
In static mixers, also called motionless or in-line mixers, a fluid is pumped through a pipe containing stationary blades. This mixing technique is particularly well suited for laminar flow mixing because it generates only small pressure losses in this flow regime. This example studies ... Per saperne di più
A demonstration of topology optimization using the Structural Mechanics Module and the Optimization Module. The classical MBB beam is solved in 2D using a Helmholtz filter and Solid Isotropic Material Penalization (SIMP) technique to recast the original combinatorial optimization problem ...

This tutorial is intended as a simple example showing how to model piezoelectric devices using the layered shell functionality. Two cases of material orientation are investigated. In the first case, the pole axis is normal to the shell surface, which results in a change in thickness of ... Per saperne di più
A modern high-power industrial fiber laser system can deliver up to 3kW of single-mode laser radiation on to surfaces to be cut, drilled, welded or marked. Even using highly transmissive materials, the optical component used to focus the laser beam onto target surfaces can be affected ... Per saperne di più
This tutorial example models the currents and the concentration of dissolved metal ions in a battery (corrosion cell) made from an orange and two metal nails. This type of battery is commonly used in chemistry lessons. Instead of an orange, lemons or potatoes can also be used. Per saperne di più
