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 model solves for a one-dimensional capacitively coupled plasma reactor in a mixture of argon/oxygen. Important aspects and strategies for modeling electronegative discharges are discussed. Per saperne di più
Side reactions and degradation processes may lead to a number of undesirable effects, causing capacity loss in lithium-ion batteries. Typically, aging occurs due to multiple complex phenomena and reactions that occur simultaneously at different places in the battery, and the degradation ... Per saperne di più
In this example, the coupling between Multibody Dynamics and Rotating Machinery, Magnetic for performing electromagnetic and mechanical analysis is demonstrated. A permanent magnet motor with 10 rotor poles and 12 stator slots is modelled in 2D. The magnets are attached to the ... Per saperne di più
The magnets in an Interior Permanent Magnet (IPM) motor are embedded in the rotor core, where they form narrow regions known as bridges. The thickness of the magnetic bridge is an important parameter to consider in design, both from the electromagnetic and the mechanical perspectives. As ... Per saperne di più
This model presents two examples of topology optimization of the magnetic circuit of a loudspeaker driver. A first optimization is used to find the design of a nonlinear iron pole piece and top plate that maximize the BL factor at the resting position (small displacements), while ... Per saperne di più
An AC contactor is a particular type of magnetic switch device, which is activated by a primary coil fed by an alternating current. Unlike DC switches, such devices can suffer from a tendency to reopen when the AC current crosses zero. The addition of a shading coil that supports ... Per saperne di più
This model simulates a 16-level, first-order, focusing Fresnel lens with 50 µm diameter and 150 µm focal length. In one simulation, the Electromagnetic Waves, Frequency Domain interface computes the electric field in the Fresnel lens and the surrounding air domain extended to the focal ... Per saperne di più
Surface chemistry is often an overlooked aspect of reacting flow modeling. This tutorial model shows how surface reactions and species can be added to study processes like chemical vapor deposition (CVD). The tutorial then models silicon growth on a wafer. Initially, the example uses a ... Per saperne di più
This model simulates atmospheric galvanic corrosion of a busbar, which includes a copper flange, an aluminum alloy flange in contact with a zinc nut and bolt. The Secondary Current Distribution interface is used to solve for the electric potential in electrode domain and Current ... Per saperne di più
Galvanic corrosion between two different phases (alpha and beta phases) in a metallic (magnesium) alloy is simulated for a representative cross-sectional microstructure configuration. A key feature in the model formulation is the implementation of both anodic and cathodic regions at ... Per saperne di più
