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 Biconical antenna is a type of wideband antenna with omni-directional radiation pattern in the H-plane similar to a dipole antenna. A coaxial feed is connected to the radiators using two 90 degree bent arms. The model shows that the biconical antenna works well in applications ... Per saperne di più
Modern integrated circuits are available as plastic encapsulated microcircuits (PEM). These devices are molded out of polymeric materials and epoxy resins in order to protect the internal semiconductors. Unfortunately, polymeric mold compounds absorb moisture when exposed to a humid ... Per saperne di più
This is a model of a MEMS microphone solved in the frequency domain including the DC prestress effects. The model is set up using the Electromechanics multiphysics interface, Thermoviscous Acoustics, and Pressure Acoustics. The microphone consists of a perforated plate and a prestressed ...

Reflow soldering is an important process in IC packaging. In reflow soldering, the solder materials are melted to create joints between electrical components and the PCBs for structural and electrical connections. This model demonstrates the process of attaching chips to a PCB by reflow ... Per saperne di più
An Einzel lens is an electrostatic device used for focusing charged particle beams. It may be found in cathode ray tubes, ion beam and electron beam experiments, and ion propulsion systems. This particular model consists of three axially aligned cylinders. The outer cylinders are ... Per saperne di più
This example models the transient heating, and final temperature, of a disc brake of a car in brake-and-release sequence. It is important to model the transient heating and the following convective cooling to determine the minimum interval between a series of similar brake engagements. ... Per saperne di più
This model couples the Navier Stokes equations and the heat transfer equations to examine density driven flow of free fluids. Here the fluid is in a square cavity with a heated wall. The buoyancy force is a Boussinesq term added to the Navier-Stokes equations. The equation is ... Per saperne di più
Droplet evaporation is ubiquitous in everyday life, and is essential in many industrial processes such as ink-jet printing, cleaning or coating of surfaces, and phase change heat transfer. In this model, a water droplet placed on a solid substrate evaporates in air. We solve the ... Per saperne di più
This example analyzes the deformation of a feeder clamp under stress. The clamp secures a feeder that carries high-frequency electromagnetic fields, and it’s important that it remains as straight as possible. Forces on the clamp include both those from the feeder as well as those on the ... Per saperne di più
Electromagnetic waves that are confined to propagate along a surface, such as surface plasmon polaritons (SPPs), are of great research interest due to their potential applications in nanoscale manipulation of light. This model demonstrates how to set up a simulation of the propagation ... Per saperne di più
