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.
Combinations of optical devices such as polarizers and wave retarders can be used to control the intensity and polarization of transmitted radiation. In this tutorial, two linear polarizers with orthogonal transmission axes are used to reduce the intensity of a ray to zero. Then the ... Per saperne di più
This model simulates a cylindrical furnace with isotropic scattering. It validates the use of the Discrete Ordinates Method for 2D axisymmetric cases, comparing the results with the highly accurate Monte Carlo method. The setup and reference Monte Carlo values are given in: R .P. Gupta, ... Per saperne di più
This is a busbar configuration with an AC analysis. The configuration is similar to the introductory tutorial in the book Introduction to COMSOL Multiphysics. However, two conductors are added to represent a more realistic case of magnetic fields surrounding the busbar. The results ... Per saperne di più
In complex mechanical systems, it can be challenging to find an optimal (or even good enough) solution only through engineering insight or trial-and-error procedures. Using mathematical optimization methods can then be an efficient path to a better design. In this example, a link ... Per saperne di più
The study explores charge transport dynamics in polyethylene, a common solid dielectric insulation material. It employs a bipolar charge transport model to calculate the densities of electrons, holes, and their trapped counterparts. The simulation's outcomes for discharge current and ... Per saperne di più
This model simulates convective heat transfer in a channel filled with water. To reduce memory requirements, the model is solved repeatedly on a pseudo-periodic section of the channel. Each solution corresponds to a different section, and before each solution step the temperature at the ... Per saperne di più
This tutorial model can be used to learn how to calculate mass and energy balances. Get a detailed demonstration in this blog post: How to Calculate Mass Conservation and Energy Balance Per saperne di più
Soft permanent magnets like AlNiCo are easily demagnetized if handled incorrectly. This is a demonstration of how to model the self-demagnetization of a cylindrical AlNiCo magnet when moved out of its associated/protective magnetic circuit. The modeling is performed in three steps: The ... Per saperne di più
This tutorial demonstrates how to modify a concentration-independent (also known as a secondary current distribution) liquid alkaline water electrolyzer with concentrated electrolyte theory to explicitly resolve local electrolyte and solvent concentrations (thereby creating a tertiary ...
