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 tutorial explores how pulse reverse plating can be used as an additive-free alternative to attenuate small protrusions during copper metal deposition. By matching the process parameters, including the length of the forward and reverse pulses (duty cycles), a bright mirror-like metal ... Per saperne di più
This example models cathodic protection of a steel reinforcing bar in concrete. Three different electrochemical reactions are considered on the steel surface. Charge and oxygen transport are modeled in the concrete domain, where the electrolyte conductivity and oxygen diffusivity depend ... Per saperne di più
An electrostatically actuated MEMS resonator is simulated. The device is driven by an AC + DC bias voltage applied across a parallel plate capacitor. In this example, the pull-in and pull-out voltages of the resonator are computed. This is done via a quasi-static analysis of the ... Per saperne di più
Some positive electrode materials are known to deteriorate in overcharged lithium-ion battery cells. Predominantly, manganese containing electrode materials such as LMO and NMC can loose capacity due to manganese dissolving from the materials at overcharge. This decomposition is a ...

This model describes the pressure wave propagation in a muffler for an internal combustion engine. The purpose of the model is to show how to analyze both inductive and resistive damping in pressure acoustics as well as coupling the fluid to the surrounding elastic shell structure of the ...

This example demonstrates how to use the Electrostatic interface to calculate the surface electric field of a typical high-voltage insulator. It is shown that the inhomogeneity and the maximum of the surface electric field are greatly reduced with the installation of the grading rings. ... Per saperne di più
Delamination or the separation of layers is a common failure mode in laminated composite materials. Various factors, including loading, defects in the material, and environmental conditions can trigger the initiation and propagation of layer separation. This leads to degraded structural ...

In these tutorial series, we demonstrate how to use the Offset Faces and Transform Faces operations as a way to reparameterize existing holes in a bracket geometry imported from a STEP file. The mass of the bracket is minimized with limits for both the lowest natural frequency, and for ... Per saperne di più
This model demonstrates how to perform a hearing aid acoustic feedback response analysis, including both the in-ear hearing aid and the hearing aid cassette. The hearing aid modeled is a ReSound OMNIA™ device from GN Hearing A/S. The hearing aid is tested on a combined pinna and ear ... Per saperne di più
A deceptively simple system of two species and two reactions, describing the autocatalytic conversion of a substance, is shown to display a surprisingly exotic behavior. Starting from a 0D CSTR description, a 2D reaction-diffusion problem is formulated showing rich patterns stemming from ... Per saperne di più
