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.
In this model of a single-beam optical trap, SiO2 nanospheres in streaming water pass by or get captured depending on where they are released from. The electromagnetic force on the particles is calculated in the Electromagnetic Waves, Frequency Domain interface, with a Gaussian ... Per saperne di più
When evaluating the efficacy of treatments for ocular diseases, modeling and simulation can be used for pharmacokinetic analysis by visualizing drug concentration and how it spreads through the eye over time. In this simplified pharmacokinetic model of a human eye, a small patch is ... Per saperne di più
During manufacturing or in-service use, the geometric shape of structural components can deviate from their intended design. For example, a hole may lose its perfectly circular form, making it important to measure and control this deviation. The process of quantifying such deviations is ... Per saperne di più
This example exemplifies how to model the Beer-Lambert law using the core functionality of COMSOL Multiphysics. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Modeling Laser-Material Interactions with the Beer-Lambert Law". Per saperne di più
This model demonstrates 2D topology optimization for the problem of minimum mass subject to a compliance constraint and a stress constraint. The stress constraint is implemented with a P-norm global aggregation function. The stress input to this is interpolated differently than the Young ... Per saperne di più
Pitting corrosion is localized corrosion by which local cavities, pits, are formed on a seemingly initially smooth metal surface. A pit may be initiated due to small surface defects, such as inhomogeneities in composition or shape, or from mechanical abuse. How and if the pit grows ... Per saperne di più
Creating irregular geometries can be a good solution, even the only option, for some types of applications. These files present a way to use a text file with material properties defined in coordinates to assign different materials even though there is only one regular domain. The same ...

Gradient-based optimization is an efficient way of computing better values for many control variables. This example optimizes diameters of individual members in a truss structure such that the structure becomes stiffer without adding mass to the structure. The structure will be only be ...

Surface reactions with adsorption-reaction-desorption steps are common in for example photocatalysis and biosensors. A flow cell in a biosensor contains an array of micropillars for adsorption of for example antigens in aqueous solutions. A signal proportional to the surface coverage can ... Per saperne di più
This tutorial model demonstrates the use of the features for heat transfer in layered shells, to account for the curvature of the layers when applying heat fluxes and heat sources. The results obtained with the Heat Transfer in Shells interface applied to a boundary (with extra ... Per saperne di più
