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 model presents a 2D axisymmetric dipolar microwave plasma source sustained through resonant heating of the electrons. This is known as electron cyclotron resonance (ECR), which occurs when a suitable high magnetic flux density is present along with the microwaves. This is an ... Per saperne di più
Electrical events, such as an overcurrent or overload, can seriously damage electrical circuits or power lines. To avoid expensive replacements of critical parts, electric switch circuit breakers can be installed. These mechanically interrupt the current flow or surge by moving a plunger ... Per saperne di più

An electrostatically actuated MEMS resonator is simulated in the time and frequency domains. The device is driven by an AC + DC bias voltage applied across a parallel plate capacitor. The dependence of the resonant frequency on DC bias is assessed, and frequency domain and transient ... Per saperne di più
This app demonstrates the usage of a surrogate model function for predicting the cell voltage, cell open circuit voltage and internal resistance of an NMC111/graphite battery cell undergoing a battery test cycle. The surrogate function, a Deep Neural Network, has been fitted to a ... Per saperne di più
This model presents a study of the current density distribution in a solid oxide fuel cell (SOFC). The model includes the full coupling between the mass balances at the anode and cathode, the momentum balances in the gas channels, the gas flow in the porous electrodes, the balance of ...

The primary defense of a submarine lies in its capacity to remain hidden during operation. As radio waves are strongly absorbed by seawater, sound navigation ranging, or sonar, is one of the main methods used for the detection of submarines. Sonar systems are also used for underwater ...

This example models the flow and mass transport in the channels and the gas diffusion layer (GDL) of a polymer electrolyte fuel cell. The cathode electrode reaction is modeled as a boundary condition, where the local current density depends on the overpotential and the local oxygen ... Per saperne di più
This benchmark demonstrates how to use the Beam interface in the Structural Mechanics Module. It calculates the deformation, section forces, and stresses in a cantilever beam as well as a number of eigenfrequencies. It also illustrates how to use the Beam Cross Section interface to ...

This suite of examples illustrate the modeling of selective NO reduction, that occurs as flue gases pass through the channels of a monolithic reactor in the exhaust system of a motored vehicle. The simulations are aimed at finding the optimal dosing of NH3, the reactant that serves as ... Per saperne di più
