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 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
This is a tutorial how to set up electric machinery in 3D using a combination of the magnetic fields and magnetic fields no currents interfaces. Per saperne di più
This tutorial series demonstrates three different approaches to remove small geometric entities from an imported 3D CAD geometry of a wheel rim: the Repair operation, the Defeaturing tools, and the Remove Details operation. Use Repair to automatically find and remove small entities ... Per saperne di più
This model shows how to simulate carburization and quenching of a steel gear. Diffusion of carbon into the surface of the gear affects the onset of martensitic transformation. Residual stresses are computed, and it is shown that high residual compressive stresses appear at the root of ... Per saperne di più
Electromagnetic heating is ideally suited for modeling in COMSOL Multiphysics. This model shows the area of hyperthermic oncology but the modeling issues and techniques are generally applicable to any problem involving electromagnetic heating. The purpose of this model is to compute the ... Per saperne di più
Frequency-selective surfaces (FSS) are periodic structures with a bandpass or a bandstop frequency response. This model shows that only signals around the center frequency can pass through the periodic complementary split ring resonator layer. Per saperne di più
In this tutorial model, a step thrust bearing is shape optimized to maximize the bearing capacity. A step thrust bearing consists of a stepped bearing surface on which the end of the shaft rotates. The entire assembly is submerged in a lubricant. The shaft collar is assumed to be ... Per saperne di più
Impressed current cathodic protection is a commonly employed strategy to mitigate the ship hull corrosion where an external current is applied to the hull surface, polarizing it to a lower potential. In this model, the effect of propeller coating on the current demand is demonstrated. Per saperne di più
In an alkaline electrolyzer stack, all cells share the same electrolyte. As a result of all cells being in ionic contact, parasitic shunt currents flow between the cells through the manifolds and the electrolyte channels, on both the inlet and outlet side. This example models a ... Per saperne di più
Copper electrowinning is the process of copper extraction from an electrolyte solution and its deposition at the cathode surface, by passing an external current through the electrolytic cell and using an insoluble anode. During the process, oxygen bubbles are generated at the anode ... Per saperne di più
