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 tutorial model demonstrates the use of the multiphysics coupling feature Thermal Connection, Layered Shell, Surfaces. In this model, three layered shells are connected to heat domains by interior and exterior boundaries. The results obtained with the Heat Transfer in Shells ... Per saperne di più
This model simulates a cylindrical furnace with isotropic scattering. It validates the use of the Discrete Ordinates Method for 2D axisymmetric cases, comparing the results with the highly accurate Monte Carlo method. The setup and reference Monte Carlo values are given in: R .P. Gupta, ... Per saperne di più
The level set method is well suited for problems with moving boundaries in which the geometry’s topology changes with time. A bubble of oil that travels up through water and finally merges with oil at the top causes this kind of topology change. For problems where the topology is ... Per saperne di più
In this example, the eigenmodes of a structural damper are computed. In the damper, most of the deformation is controlled by the viscoelastic domains, which have strongly frequency-dependent stiffness and damping properties. This leads to a nonlinear eigenfrequency problem, which can be ... Per saperne di più
This example models the flow and mass transport in the channels and the gas diffusion layer (GDL) of a polymer electrolyte fuel cell. The cathode electrode reaction is modeled as a boundary condition, where the local current density depends on the overpotential and the local oxygen ... Per saperne di più
The Pipe Flow interface allows you to simulate non-Newtonian fluids flowing in pipes. This example models a coal slurry being transported in a pipe system where the pipe diameter changes in different sections. The slurry behaves as a non-Newtonian fluid described by the power law model. ... 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 ...

For slender structures, buckling is a catastrophic instability if the service load is above the critical limit. For such structures, it can be important to study the behavior of the structure beyond the critical buckling load, which is known as postbuckling analysis. Tracing the ... Per saperne di più
The thermal stress in a layered plate is studied in this example. A plate consisting of two layers, a coating and a substrate layer, is stress and strain free at 800 degrees C. The temperature of the plate is reduced to 150 degrees C and thermal stresses are induced due to the difference ... Per saperne di più
