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 simulates the propagation of a double-headed streamer in nitrogen at atmospheric pressure. Initially, electron-positive ion clusters were introduced between two parallel electrodes, subjecting the gas to a strong background electric field of 52 kV/cm. Subsequently, both the ...

This tutorial demonstrates a full electro-vibroacoustic analysis of a conceptual electrostatic speaker driver, composed of thin conducting plastic diaphragm residing between two perforated metal sheets called grids or stators. When an audio signal is applied to the grids (out of phase), ... Per saperne di più
This model aims to demonstrate how a multilayer insulation can affect the temperature distribution of a satellite orbiting around the Earth. It is based on the Spacecraft Thermal Analysis model available in the Application Library. Per saperne di più
Light Detection And Ranging (LIDAR) is used extensively in self-driving cars to perform the quantitative ranging of the surroundings obstacles. The LIDAR system consists of a laser beam which gets broadened using a MEMS mirror with a particular horizontal and vertical field of view ... Per saperne di più
This model demonstrates how to optimize the charging profile of a battery using gradient based optimization. The optimization solver minimizes the time required for charging the battery from 0% to 90% state of charge, while at the same time constraining the amount lithium inventory lost ...

The model of 1D Dielectric Barrier Discharge (DBD) has been recomputed with the three different kinds of electron energy distribution functions (EEDFs): The Maxwellian function The Druyvesteyn function The computed EEDF based on the Boltzmann Equation, Two-Term Approximation ... Per saperne di più
The present model demonstrates diffusion-controlled electrodeposition of copper on microstructured band electrode arrays (MEA). Mass transport by Fickian diffusion of copper ions is solved using the Transport of Diluted Species interface. Dendrite formation as a consequence of diffusion ... Per saperne di più
This example studies heat transfer in a square column. Cold and hot temperature conditions are applied to the boundaries. Due to the symmetry of the problem, the geometry is simplified to half of the square. The temperature field is compared with the analytic data. This example ... Per saperne di più
A steel ball is pressed down against a rubber membrane. When the contact pressure exceeds a certain value, the two parts start sticking together. When the ball is retracted, the membrane is pulled upwards in the bonded region. During the retraction, the bond is partially broken. This ... Per saperne di più
This model simulates the propagation of a positive streamer in a weak electric field where the process of photoionization is essential to provide seed electrons at the front of the streamer head. The simulated electric field and electron density as a function of time agree well with that ... Per saperne di più
