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 conceptual example shows how to handle a transient contact problem with stick-slip friction transition. A soft hollow pipe subjected to gravity is released at the top of a halfpipe. The pipe motion varies between sliding and rolling, depending on its position in the halfpipe and its ... Per saperne di più
This benchmark model computes the pressure in a system of outgassing pipes with a high aspect ratio. The results are compared with a 1D simulation and a Monte-Carlo simulation of the same system from the literature. Per saperne di più
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 model studies a part of a shell-and-tube heat exchanger where hot water enters from above. The cooling medium flows through the tubes that, in this model, impose a constant temperature at the walls. Furthermore, the tubes are assumed to be made of stainless steel and the heat flux ...

In this example of a peristaltic pump, rollers squeeze a flexible tube and the compression drives a fluid through the tube. The model demonstrates how to use the Fluid-Structure Interaction interface. The main advantage of the peristaltic pump is that no seals, valves or other internal ... Per saperne di più
This example illustrates the use of the Maxwell-Stefan diffusion model available with the Transport of Concentrated Species interface. It models multicomponent gas-phase diffusion in a Stefan tube in 1D. In this case, it is a liquid mixture of acetone and methanol that evaporates into ... Per saperne di più
The acoustic field in a model of an axially symmetric lined aero-engine duct, based on modal sound transmission, is analyzed. The source is generated by a single mode excitation at a boundary. Sources and nonreflecting conditions are applied using port boundary conditions. The model ... Per saperne di più
This tutorial simulates the turn-on transient (forward recovery) of a simple PIN diode, based on the book "Fundamentals of Power Semiconductor Devices" by B. J. Baliga (p. 242, 2008 edition). The diode is current driven with a constant ramp rate of 1e9, 2e9 and 1e10 A/cm^2/sec and a ... Per saperne di più
Shell-and-tube heat exchangers are commonly used in oil refineries and other large chemical processes. In this model, two separated fluids at different temperatures flow through the heat exchanger, one through the tubes (tube side) and the other through the shell around the tubes (shell ...

This tutorial simulates the turn-off transient (reverse recovery) of a simple PIN diode with an inductive load, loosely based on the book "Fundamentals of Power Semiconductor Devices" by B. J. Baliga (p. 256, 2008 edition). Unlike the book, which assumes an initial constant current ramp ... Per saperne di più
