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.
Freeze-drying, or lyophilization, is a process for drying heat-sensitive substances such as foods, blood plasma, and antibiotics. The wet substance is frozen and then, through sublimation, ice (or some other frozen solvent) is removed in the presence of a high vacuum. This example ... Per saperne di più
Rechargeable lithium-air batteries have recently attracted great interest mainly due to their high energy density. The theoretical value is about 11400 Wh/kg which is around 10 times greater than the lithium-ion batteries. In this tutorial, discharge of a lithium-air battery is ... Per saperne di più
This tutorial introduces the use of topology optimization in acoustics. The goal of the optimization is to find the optimal material distribution (solid or air) in a given design domain, here the ceiling of a 2D room, that minimizes the average sound pressure level in an objective ...

This is a model of an RF waveguide bend with a dielectric block inside. There are electromagnetic losses in the block as well as on the waveguide walls which cause the assembly to heat up over time. The material properties of the block are functions of temperature. The transient thermal ... Per saperne di più
This conceptual example shows how to calculate critical points in models with contact. The model consists of two contacting arches modeled with the Shell interface. The contact problem is solved using the penalty method. The upper arch is loaded with displacement controlled edge loads ... Per saperne di più
A cable is a structural member which has stiffness only in its tangential direction, but virtually no bending stiffness. When supported only at its two ends it deflects under gravitational load forming a curve known as catenary. This example shows how to model components such as cables, ... Per saperne di più
This conceptual example shows how to calculate critical points in models with contact. The model consists of a block modeled with the Solid Mechanics interface pressing on an arch modeled with the Shell interface. The contact problem is solved using the augmented Lagrangian method. The ... 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 square airbag is inflated using constant air pressure. In some regions of the airbag the material wrinkles during inflation, as negative principal stresses develop. The wrinkling membrane model within the tension field theory gives a correct description of the stress distribution and ... Per saperne di più
In this tutorial model, a six step thrust bearing is analyzed. A step thrust bearing consists of a stepped bearing surface on which the end of the shaft rotates. The entire assembly is submerged in a lubricant. The shaft collar is assumed to be spinning without any axial motion in the ... Per saperne di più
