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 example models the flow in a 90-degree pipe elbow. The flow is simulated using the k-omega turbulence model. The result is compared to engineering correlations. Per saperne di più
This tutorial digs deeper into the investigation of rate capability in a battery and shows how the Lithium-Ion Battery interface is an excellent modeling tool for doing this. The rate capability is studied in terms of polarization (voltage loss) or the internal resistance causing this ... Per saperne di più
This model computes the particle flux, number density and pressure on the surface of a plate that rotates in a highly directional molecular flow. The results obtained are compared with those from other, approximate, techniques for computing molecular flows. Per saperne di più
This model analyzes lightning surges in an offshore wind farm. When a lightning strike with a current of 20 kA hit one wind turbine, the induced electric fields in adjacent wind turbines were computed. Per saperne di più
An electrodynamic ion funnel provides an efficient means of transferring ions from regions of high pressure to high vacuum. The ion funnel can couple devices which generally operate at pressures of different orders of magnitude, such as ion mobility spectrometers and mass spectrometers, ... Per saperne di più
This example presents transient analysis of the wave propagation in rock mass caused by a short duration load on the surface. Such loads are typical during tunnel constructions and other excavations using blasting. The example shows the use of the Low-reflecting boundary conditions to ... Per saperne di più
This model simulates the dynamics of the shock absorber used in a landing gear mechanism of an aircraft. It analyses the stresses, as well as the heat generated in the landing gear components due to the energy dissipated in the shock absorber. A prismatic joint, with spring and damper, ...

A magnet moving axially through the center of a coil will induce a voltage across the coil terminals. One practical application of this is in shaker flashlights, where the flashlight is vigorously shaken back and forth, causing a magnet to move through a multi-turn coil, which provides ...

This model and tutorial demonstrates the use of an Application Method to compute and plot the geometric Modulation Transfer Function (MTF) for the Petzval Lens. Per saperne di più
This model studies the temperature effects on the viscoelastic stress relaxation in a long thick-walled cylinder. In particular, decay of the stresses under the influence of the temperature field during a period of two hours is studied. A four-term generalized Maxwell model represents ... Per saperne di più
