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.
Micromirrors are used in certain MEMS devices to control optic elements. This example model illustrates a mirror that is initially actuated for a short time and then exhibits damped vibrations. It simulates a vibrating micromirror surrounded by air and uses the Thermoviscous Acoustics, ... Per saperne di più
The compressible Euler equations are implemented in the Wave Form PDE interface with nodal discontinuous Lagrange shape functions to compute the flow in a shock tube. The purpose of this application is to simulate the flow in the tube and estimate the distributions of pressure, density, ... Per saperne di più
Surface micromachined thin films are often subject to residual stress. This COMSOL Multiphysics example describes a thin film resonator with straight or folded cantilever beam springs. The resonance frequencies of the resonator are affected by thermal stress. Using folded springs ... Per saperne di più
This model demonstrates how to set up a phase field damage multiphysics model to predict crack propagation in thermoelastic solids under large deformations. The crack-driving force depends on the principal stresses, which in turn depend on the temperature distribution in the solid ... Per saperne di più
This example shows how to model secondary current distribution and electrode growth with a moving geometry. To avoid numerical instabilities, a seed layer is introduced in the initial geometry to obtain a right angle at the edge between the growing electrode and the insulator. Per saperne di più
This is a model of the secondary current distribution in a zinc electrowinning cell. The model investigates the impact on the current distribution when changing the electrode alignment in a parametric study. The geometry is in 2D. Per saperne di più
The impressed current cathodic protection (ICCP) system is often employed to mitigate corrosion of buried pipelines in the oil and gas industry. Metallic objects such as buried pipelines, which are present within the current flow of the ICCP system, may suffer from the stray current ... Per saperne di più
The following example is a 2D tutorial model of a lithium-ion battery. The cell geometry is not based on a real application; it is only meant to demonstrate a 2D model setup. Per saperne di più
Electrochromic devices (ECDs) may be employed in ”smart” windows, for instance in buildings or motor cycle visors, where the transparency of the device can be controlled by applying a voltage. ECDs make use of the fact that the absorbance of visual light for a chemical species in a ... Per saperne di più
This model presents a method to analyze acoustic damping pads. These pads use a constrained layer of viscoelastic material to dissipate energy and thus reduce the energy radiated as noise. Damping pads are used in many different industries to reduce the noise generated by vibrating ... Per saperne di più
