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.
Various boundary conditions are employed in the computation of homogenized properties for heterogeneous materials. The choice between periodic or homogeneous boundary conditions depends on whether the infinitesimal volume is modeled as a repeating unit cell (RUC) or a representative ... Per saperne di più
When radiation occurs across a very narrow gap this is often well-approximated as radiation between infinite parallel plates. This model considers three aluminum plates separated by narrow air gaps. The model compares the classical approach, based on the Surface-to-Surface Radiation ... Per saperne di più
The "Smart Radiator Device," a multilayer structure, has the capability to control thermal emissivity at different temperatures. This multilayer structure is lightweight thus finds its application in spacecraft mission. The thermochromic vanadium oxide (VO2) material is the heart of ... Per saperne di più
This model demonstrates the transient heating of a sample of material with a time- and space-varying heat load. Issues of solution accuracy with respect to mesh and solver tolerance can be quickly studied on this model. Learn more about this model in the accompanying blog post: "Intro to ... Per saperne di più
How the open-circuit voltage (OCV) of a lithium-ion battery varies with the state of charge is governed by various physical properties such as the thermodynamics of the electrode reactions, the relative capacities of the electrode materials, and the amount of cyclable lithium, but also ...

This example exemplifies how curve fitting can be performed in COMSOL Multiphysics®, and how this can be applied to your modeling. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Curve Fitting of Experimental Data with COMSOL ... 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
A demultiplexer is a device that directs different frequency bands to different outputs. In this tutorial model, we will design a demultiplexer by performing shape optimization on all initial circular boundaries in a sonic crystal (phononic crystal) configuration. The model uses shape ... Per saperne di più
This example exemplifies how to model applications using the Events Interface where a thermostat is simulated. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Implementing a Thermostat with the Events Interface". Per saperne di più
These examples demonstrate how to use a job sequence to perform a programmatic sequence of operations, including solving; saving the model to file; and generating and exporting plot groups, results, and images. In the blog post associated with these files, "How to Use Job Sequences to ... Per saperne di più
