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.
Hydrogen embrittlement refers to the degradation of metal ductility due to the absorption of hydrogen. The metal becomes more brittle and thus cracks might initiate at lower stress levels. It is important to estimate hydrogen concentration and the speed at which it diffuses into the ... Per saperne di più
This model shows how to include the nonlinear (large signal) behavior of certain lumped components in a simplified loudspeaker analysis. The mechanical and electrical system is modeled using an equivalent electrical circuit. The large signal compliance CMS(x) and force factor BL(x) are ... Per saperne di più
Induction pumps are used in high temperature cooling systems. The principle of operation is equivalent to a linear three phase induction motor. The lack of moving parts and the pumped liquid being kept in a hermetically closed system are clear advantages. This model shows how to simulate ... Per saperne di più
This model calculates the current and charge characteristics of a floating gate Electrically Erasable Programmable Read-Only Memory (EEPROM) device. A stationary study demonstrates the effects of varying the charge stored on the floating gate by computing Current-Voltage curves as a ... Per saperne di più
This example shows how the mixing capability of a stirred vessel can be evaluated. To efficiently reach the steady operational conditions the turbulent flow is solved for using a frozen rotor analysis, and a following time dependent simulation. When a quasi-steady flow field has ... Per saperne di più
This model shows how to combine different types of material nonlinearity, such as creep and elastoplasticity. In this specific example you will perform a stress and nonlinear strain analysis on a thick cylinder under a nonproportional loading: an initial temperature increase followed by ...

This example shows how to make a simple model for a binary distillation process. A thermodynamics property package, available in the Chemical Reaction Engineering Module, is created to study the separation of a nonideal mixture of ethanol and water. The required equilibrium relationship ... Per saperne di più
Microlithography lenses are used to project the image of an integrated circuit onto a silicon substrate. This tutorial demonstrates how to create a 21-element fused silica lens which has a NA of 0.56 which is designed to be used at a wavelength of 248nm. The lens, which has a total ...

The first model describes the simultaneous flow of two immiscible fluids in porous media - here air displaces water in a multi-step inlet pressure experiment. We solve for the pressure and the degree saturation for the air and water within a representative volume and so track saturation ... Per saperne di più
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
