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.
This example model demonstrates four different approaches for computing the integrals of fields over arbitrarily placed geometries that can be re-positioned without having to re-solve the model. This approach is also useful if you want to integrate the results of a model over different ... Per saperne di più
This model simulates transition flow through a microchannel using the Transition Flow interface in COMSOL Multiphysics®, which solves the Boltzmann BGK equation. The analysis is carried out to understand the fluid flow behavior across five different pore-length (porosity) configurations, ... Per saperne di più
Ion beam etching is a critical technique widely used in semiconductor manufacturing, materials science, and microelectromechanical systems (MEMS). This proof-of-concept model simulates argon ion sputtering of a silicon surface using the Charged Particle Tracing interface. A Deformed ... Per saperne di più
This model demonstrates how to use the chatbot functionality in COMSOL Multiphysics® to add annotations to a model of a pacemaker electrode. To learn more about this model, see our accompanying blog post “Using the Chatbot Window in COMSOL Multiphysics®”. Per saperne di più
An interesting question was raised in the 1950s by the mathematician Ernst Straus that, in an arbitrarily shaped empty room with side walls made of perfect mirrors, will a point light source always illuminate the whole room? This question was answered by the Nobel Prize-winning ... Per saperne di più
This model compares the solution to the model equations of a tubular reactor using Danckwerts inlet and outlet conditions. A second almost identical model is defined with extra inlet and outlet sections where no reactions occur. The concentration at the beginning of the inlet section is ... Per saperne di più
A simple way to estimate the value of π is by using a pendulum, whose oscillation period can be measured and used to calculate an approximation. This simulation app is based on a model that uses the <em>Multibody Dynamics</em> interface to describe the motion of a simple ... Per saperne di più
Thermally induced transformations in solids may be modeled by using an Arrhenius law to express the dependence on temperature of the transformation rate. This tutorial model shows how to use the Irreversible Transformation subfeature, available under the Solid feature of the Heat ... Per saperne di più
This example exemplifies how to optimize the design of a capacitor through optimization. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Changing the Dimensions of a Model Using Shape Optimization". Per saperne di più
This example shows how to model isotropic volumetric growth and atrophy of soft biological tissues. The artery is represented by a cylinder that is stretched and compressed due to an applied axial load. As a result, the tissue undergoes growth and atrophy. Per saperne di più
