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 shows how to estimate the permeability of a porous material by creating a detailed fluid flow model in a small unit cell. The result of the model is a lumped permeability of the material, which can be used in homogenized models using Darcy's law or the Brinkman equations. ... Per saperne di più
This example demonstrates the Lithium-Ion Battery, Single-Ion Conductor interface for studying the discharge of a lithium-ion battery with solid electrolyte. The geometry is in one dimension and the model is isothermal. The behavior at various discharge currents and solid electrolyte ... Per saperne di più
Including circumferential displacements in a 2D axisymmetric Solid Mechanics interface allows to compute twist and bending deformations. This model determines stress concentration factors for a hollow shaft for load cases of axial extension, torsion, as well as bending, using a ... Per saperne di più
This example models the deposition of an inductor coil in 3D. The geometry includes the extrusion of the deposition pattern into an isolating photoresist mask, and a diffusion layer on top of the photoresist. The mass transfer of copper ions in the electrolyte has a major impact on the ... Per saperne di più
In this example you will build and solve a 3D beam model using the 3D Beam interface. This model shows how a thermally induced deformation of a beam is modeled. Temperature differences are applied across the top and bottom surfaces as well as the left and right surfaces of the beam. ... Per saperne di più
Modeling flow through realistic porous structures is difficult due to the complexity of the structure itself. Often, resolving the flow field in detail is not feasible; therefore, a macroscopic description of the pore scale structure, which utilize averaged quantities such as porosity ... Per saperne di più
This example is a benchmark problem for simulating phase change in porous media. It studies the melting process of an ice inclusion within porous media and therefore demonstrates how to couple Darcy's Law with the Heat Transfer in Porous Media interface including phase change. Per saperne di più
Density variations can initiate flow even in a still fluid. In earth systems, density variations can arise from naturally occurring salts, subsurface temperature changes, or migrating pollution. This buoyant or density-driven flow factors into fluid movement in salt-lake systems, saline ... Per saperne di più
In his example, the lowest natural frequency of a 3D bracket are maximized using shape optimization. Per saperne di più
In modeling of transport by diffusion or conduction in thin layers, we often encounter large differences in dimensions of the different domains in a model. If the modeled structure is a so-called sandwich structure, we can replace the thinnest geometrical layers with a thin layer ... Per saperne di più
