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 example is a variant of the Composite Thermal Barrier tutorial and shows how to set up multiple sandwiched thin layers with different thermal conductivities in two different ways. First, the composite is modeled as a 3D object. In the second approach the Lumped Thermal System ... Per saperne di più
Several factors influence a diesel particulate filter’s (DPF) efficiency and durability. Important issues include the removal of soot particles from the filter membranes and the influence of thermal stress on the ceramic structure, stress that arises during repeated operating cycles. ...

This model example simulates an air-cooled cylindrical 18650 lithium-ion battery during a charge-discharge cycle, followed by a relaxing period. A lumped (0D) cell model is used to model the battery cell chemistry, and a two-dimensional axi-symmetrical model is used to model the ... Per saperne di più
This example treats the modeling of sub-surface flow where free convection in porous media is analyzed. The results are compared with published literature in the field. The model couples the momentum balance to an energy balance through an equation, dependent on temperature, being ... Per saperne di più
A 2D model of a steel bar is used to simulate oil quenching from an austenitic state. Both diffusive and displacive phase transformations are used, and the phase composition is computed in the radial direction of the bar. Per saperne di più
This example demonstrates how to model phase transition by a moving boundary interface according to the Stefan problem. A square cavity containing both solid and liquid tin is submitted to a temperature difference between left and right boundaries. Fluid and solid parts are solved in ... Per saperne di più
In a cylindrical or prismatic battery cell, the active layers, current collector metal foils and separators are wound into a “jelly roll”. Additional tabs (metal strips) are welded to the current collector foils in order to conduct the current to the exterior of the cell can. The ... Per saperne di più
This model presents a way to compute projected area using the Surface-to-Surface Radiation interface of the Heat Transfer Module. By computing illuminated area from a set of directions on a discretized sphere, it is possible to interpolate the projected area onto any angle of incidence. ... 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
In fuel cell power generators, a steam reformer unit typically produces the hydrogen needed for the cell stack. This example illustrates the modeling of a steam reformer. The reformation chemistry occurs in a porous catalytic bed where energy is supplied through heating tubes to drive ... Per saperne di più
