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.
In this example, a random vibration test of electronic equipment is simulated. Three analyses are performed, one for acceleration in each global direction. Accelerations in the components and forces in clamping bolts are evaluated. Per saperne di più
This is a template base model containing the physics, geometry and mesh of a lithium-ion battery, defined in 1D. The model makes use of four lithiation parameters which are used to define the relative balancing of the negative and positive electrodes, as well as global cell state of ... Per saperne di più
Using a Fluid-Solid Interaction multiphysics interface, the behavior of a spring-loaded ball check valve is studied under varying functional and reverse flow. The fluid force acting on the ball opens the valve at the opening pressure. In the case of a reversed pressure, the ball comes ... Per saperne di più
Carbon dioxide in aqueous solution is highly corrosive and can cause significant damage to steel designs. Such conditions arise in pipes used in a variety of applications, especially within the petrochemical industry. In this tutorial example, turbulent flows consisting of carbon ... Per saperne di più
Modeling packed beds, monolithic reactors, and other catalytic heterogeneous reactors is substantially simplified with the Reacting Flow in Porous Media multiphysics interface. This defines the diffusion, convection, migration, and reaction of chemical species for porous media flow ... Per saperne di più
A Helmholtz coil is a parallel pair of identical circular coils spaced one radius apart and wound so that the current flows through both coils in the same direction. This winding results in a uniform magnetic field between the coils with the primary component parallel to the axes of the ... Per saperne di più
In electromagnetic simulations, such as transformers and converter stations, one often needs to include geometrically thin conductive layers. Explicitly meshing these thin layers can be computationally expensive and numerically challenging, especially when the layer thickness is much ... Per saperne di più
This model demonstrates how to optimize the charging profile of a battery using gradient based optimization. The optimization solver minimizes the time required for charging the battery from 0% to 90% state of charge, while at the same time constraining the amount lithium inventory lost ...

In this example, a heterogeneous NMC (Nickel-Manganese-Cobalt) electrode structure is generated from tomography data using a Model Method. Time-dependent discharge and electrochemical impedance spectroscopy (EIS) simulations are then made on the full 3D geometry. A solid mechanics ... Per saperne di più
This case shows how to simulate moisture transport in a homogeneous wall under isothermal conditions. With this assumption, an analytical solution can be calculated. The homogeneous layer is initialized in moisture balance. At the beginning of the simulation, the relative humidity of ... Per saperne di più
