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.
These models illustrate some important topics when modeling buckling imperfection. The Euler 2 Buckling Imperfection model shows a simple case with a cantilever beam buckling under compression. Three different buckling modes are combined as initial imperfections. The other model, ... Per saperne di più
This model shows three methods to focalise external irradiation with a convex glass lens made of either: Semitransparent Surface with no reflection. Refractive Interface following the Fresnel's relations. Dielectric Window absorbing ultraviolet and infrared radiations. Per saperne di più
This example of a plasmonic waveguide filter shows that the waveguide rejects the electromagnetic radiation of the wavelength between 1.4 um and 1.6 um, but allows the rest of the wavelength. The silver material can be modeled using the Drude-Lorentz approximation, with ε∞ = 3.7, ωp = 13 ... Per saperne di più
This model demonstrates a technique for partitioning a mesh based upon the element type. By first meshing with a boundary layer and then partitioning and creating a new mesh, it is possible to avoid modeling the interior volume of inductively heated parts, where the skin depth is small ...

Creating irregular geometries can be a good solution, even the only option, for some types of applications. These files present a way to use a text file with material properties defined in coordinates to assign different materials even though there is only one regular domain. The same ...

Gradient-based optimization is an efficient way of computing better values for many control variables. This example optimizes diameters of individual members in a truss structure such that the structure becomes stiffer without adding mass to the structure. The structure will be only be ...

This model describes a pencil beam scanning (PBS) magnet system for use in medical proton therapy. Simulations of the magnetic flux density and particle tracing are performed. Such models are useful for the design of PBS systems, particular with the advent of MR-integrated proton ... Per saperne di più
The electrodes of a lithium-ion battery are porous and consist of an active solid electrode material, a binder, and pores filled with a liquid electrolyte. Expansion of the active material due to lithium intercalation changes the volume fraction of electrolyte-filled pores in the ... Per saperne di più
This verification model analyzes the acoustics of two coupled rooms using the Acoustic Diffusion Equation interface of the Acoustics Module. The results of the model agree with numerical results that are validated against measurements in a reference paper. Per saperne di più
When computing ray intensity in 2D axisymmetric models, the wavefront associated with the propagating ray is treated as a spherical or ellipsoidal wave, instead of a cylindrical wave. This tutorial example illustrates how to set up several important features using the Ray Acoustics ... Per saperne di più
