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 2D model demonstrates how to model a galvanic couple in which the corrosion of the anode causes a geometry deformation. The parameter data used is for an Magnesium Alloy (AE44) - mild steel couple in brine solution (salt water). Per saperne di più
In modeling of transport by diffusion or conduction in thin layers, we often encounter large differences in dimensions of the different domains in a model. If the modeled structure is a so-called sandwich structure, we can replace the thinnest geometrical layers with a thin layer ... Per saperne di più
Classical MHD benchmark problem was solved analytically by J. Hartmann. He considered laminar incompressible flow between two planes (in planar duct) in transversal imposed magnetic field under next assumptions: * fully developed flow (far from inlet) * fluid properties are constant * ...

This model demonstrates the impact of convection and diffusion on the transport-limited electrodeposition of a copper microconnector bump (metal post). Microconnector bumps are used in various types of electronic applications for interconnecting components, for instance liquid crystal ... Per saperne di più
In this model, a turbocharger supported on two floating ring bearings is studied. The film forces on the ring cause it to rotate within the bearing. In steady state, the ring rotates at a constant angular speed and the torque on the ring due to the inner and outer films are balanced. ... Per saperne di più
Power lines are commonly used as a means of transmitting electrical power across large distances. In this tutorial, towers transmitting high voltage three-phase AC power are modeled, and the resulting electric field is computed. The towers have two shielding lines. The model also ...

This tutorial example serves as an introduction to the Corrosion Module and models the metal oxidation and oxygen reduction current densities on the surface of a galvanized nail, surrounded by a piece of wet wood, which acts as electrolyte. The protecting zinc layer on the nail is not ... Per saperne di più
The metal-silicon-oxide (MOS) structure is the fundamental building block for many silicon planar devices. Its capacitance measurements provide a wealth of insight into the working principles of such devices. This tutorial constructs a simple 1D model of a MOS capacitor (MOSCAP). Both ...

The classical forward problem of geoelectrics (includes electrical resistivity tomography, ERT and earlier techniques as vertical electric sounding, VES) is the calculation of potentials at a given set of electrodes (M,N) while current is injected at other electrodes (A,B) into the ...

The present model example is based on Copper Deposition in a Trench model available in Electrodeposition Application Library. The nonuniform deposition along the trench surface leads to formation of a cavity/void. Since the Deformed Geometry interface cannot handle topological changes, ... Per saperne di più
