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 model builds on the photonic crystal model, where a photonic crystal structure is studied. This structure has a band gap, so only waves within a specific frequency range will propagate through the outlined guide geometry. This model changes the position of the pillars in order to ...

In this set of verification models and associated documentation, the accuracy of electromagnetic force calculations is investigated. Using various techniques, the total force and torque on a rigid body is determined and compared to analytical models. Using fillets, advanced meshing and ... Per saperne di più
This model of a circular waveguide demonstrates how to use ports with numerical solution of the port modes. It illustrates how to align the polarization of degenerate port modes and in particular how to model and excite the TE11 mode of circular waveguides in 3D. Per saperne di più
This model exemplifies the use of the Rotating Machinery interface, which allows you to model moving rotating parts in, for example, stirred tanks, mixers, and pumps. The Rotating Machinery interface formulates the Navier-Stokes equations in a rotating coordinate system. Parts that are ... Per saperne di più
This introduction model creates a simple model of the magnetostatics problem with a wire of infinite length carrying current, which is commonly found in textbooks. Since there is an analytical solution to this problem, the model can be used to compare theory with numerical results from ... Per saperne di più
This example shows the analysis of a perforated plate loaded into the plastic regime. The purpose of the analysis is to demonstrate how plastic strains can be mapped between dissimilar meshes. Per saperne di più
A strong permanent magnet is placed close to a clamped thin plate made of iron. The magnetic force causes the plate to be deflected. This example studies the plate's elastic deformation and stress. The deformation of the plate has an influence on the distribution of the magnetic field. ... Per saperne di più
This tutorial demonstrates the use of the density-gradient formulation to include the effect of quantum confinement in the device physics simulation of a silicon inversion layer. This formulation requires only a moderate increase of computational resources as compared to the conventional ... Per saperne di più
In this tutorial model, the flow in a pipe with a bend is computed using the Pipe Flow interface. The computed fluid load is used as input to a stress analysis in the Pipe Mechanics interface. Gravity loads from the pipe and fluid are also taken into account. Per saperne di più
In this model, sound created by a vibrating piston radiates through a baffled pipe. The impedance is measured and then used in an impedance boundary condition that replaces the surrounding air domain. This technique can be employed to reduce solution time and memory usage for large ... Per saperne di più
