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.
A circular metal bar is subjected to uniaxial tension. As an effect, large plastic strains develop. The material is elastoplastic with nonlinear isotropic hardening. As the elongation is increased, the decrease in radius becomes strongly nonuniform, so called "necking". The development ... Per saperne di più
This is a benchmark model for flexible multibody dynamics. This model simulates the dynamic behavior of a planar four-bar mechanism when one of the joints has a defect. The out-of-plane motion in the mechanism, caused by the defect in the joint, is compared with the results from the ... Per saperne di più
Different types of elements can be used for modeling a rotor, depending on the level of complexity and the type of the system being modeled. The modeling steps and representation of the results will vary with the type of idealization. In this tutorial model, an eigenfrequency analysis is ... Per saperne di più
Large lithium-ion batteries are widely deployed in electric vehicles and for stationary energy storage applications. In the (stacked) pouch battery cell design, all current exits the cell on the cell "tabs", and as the cell size and power increase, the voltage gradients in the highly ... Per saperne di più
This model uses the Optimization interface to solve the inverse problem for determining the spatially variable hydraulic conductivity on a discretized quadratic grid from a number of aquifer pump tests. Because the number of observations is smaller than the number of unknown parameters, ... Per saperne di più
Power inductors are a central part of many low-frequency power applications. They are, for example, used in the switched power supply for the motherboard and all other components in a computer. Computer simulations are necessary in the design of such inductors. This model calculates the ... Per saperne di più
This tutorial model presents a study of a negative corona discharge in dry air at atmospheric pressure in a point-to-plane configuration. An elliptical electrode with millimeter dimensions creates a high intensity electric field where the corona discharge occurs. A ground plane is placed ... Per saperne di più
Micromixers can either be static or dynamic depending on the required mixing time and length scale. For static mixers, the Reynolds number has to be suitable high to induce turbulence enhanced mixing. Often micromixers operate in the laminar flow regime due to their small characteristic ...

This model illustrates the dynamics of helical gears. It is built using the gears functionality in the Multibody Dynamics interface in COMSOL Multiphysics. A transient study is performed to analyze the effect of constant gear mesh stiffness, varying gear mesh stiffness, and the ... Per saperne di più
Steel pipelines are often subjected to complex stress/strain conditions in the oil and gas industry. Additionally, pipes are subjected to significant longitudinal strain due to soil movement. For the elastoplastic stress simulation, the Solid Mechanics interface is used with the small ... Per saperne di più
