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.
Electron transport in low-temperature plasmas depends strongly on the electron energy distribution function (EEDF), which is often approximated as Maxwellian but is frequently nonequilibrium in reality. Incorporating nonequilibrium EEDF behavior into spatially dependent models often ... Per saperne di più
This application demonstrates how the Application Builder in the COMSOL Multiphysics® software can be used to make advanced cable modeling available to a general audience. At its core is a multiphysics model based on the technology introduced in the Cable Tutorial Series. The ... Per saperne di più
This model analyzes Joule heating and thermal expansion in a bond wire in an LED. Its purpose is to estimate the temperature increase and the resulting mechanical stresses in the bond wire due to thermal expansion. The magnitude of these stresses can be used to assess the risk of fatigue ... Per saperne di più
This model presents a 2D simulation of transient arc discharge movement along guided copper rails. While accurately modeling transient arcs typically requires a 3D simulation, the 2D approach offers greater efficiency and remains valuable for initial investigations and demonstration ...

This model demonstrates how a nonlinear equation system can be setup to solve for the eigenfrequencies of a symmetric laser cavity. The model uses the bidirectional formulation of the Electromagnetic Waves, Beam Envelopes physics interface. The computed eigenfrequencies are verified with ... Per saperne di più
A 3D silicon waveguide is set up with rib and slot configurations. The meshing includes physics-controlled mesh, with the number of longitudinal mesh elements set to 50 to visualize the wave oscillation. The detailed discussion of the model setup is discussed in the blog post: "Silicon ... Per saperne di più
This example demonstrates how to compute transmission line parameters such as series resistance, series inductance, shunt conductance, and shunt capacitance per unit length using the predefined Transmission Line RLGC Parameters multiphysics interface. The demonstration also includes the ... Per saperne di più
In this model, an eigenfrequency analysis is performed to give a bandgap analysis of a 1D multilayer photonic crystal extending to infinity in +/- y direction. We perform the bandgap analysis for three different cases of material properties, as discussed in Chapter 4 of Ref. 1. Case ... Per saperne di più
The AC/DC magnetic interfaces support material models defined in external C code. You can access external material functions, written in C code, which have been compiled into a shared library. By writing a wrapper function in C code, you can also use material functions written in another ... Per saperne di più
Optical computing has been a promising paradigm alternative to the current electronic computers. This model simulates an optical 4-by-4 unitary matrix multiplication device based on a network of six Mach–Zehnder interferometers (MZIs). A more detailed description of this model can be ...
