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 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 demonstrates a simulation setup for exciting surface plasmon polaritons using Otto and Kretschmann configurations. The underlying mechanism is enabled by the interplay between total internal reflection and evanescent-wave coupling phenomena. It also calculates the ... Per saperne di più
Inductive devices experience capacitative coupling between conductors at high frequencies. Modeling this phenomenon requires that you describe electric fields that have components both parallel with and perpendicular to the wire. This consideration might lead to the conclusion that a 3D ... Per saperne di più
This is a model of a MEMS microphone solved in the frequency domain including the DC prestress effects. The model is set up using the Electromechanics multiphysics interface, Thermoviscous Acoustics, and Pressure Acoustics. The microphone consists of a perforated plate and a prestressed ...

This app simulates sedimentation of particles or agglomerations of particles in a solution. The distribution of particles or agglomerations of particles is taken into account. Per saperne di più
This model simulates the propagation of two frequency bands in a photonic crystal with three ports. The crystal is initially symmetric, so that the two frequency bands are directly equally to either output port. The model optimizes the position of the pillars in order to make the two ...

This tutorial model shows how to model a structure using both shells and solids, and how to create the transition between them. Results are compared between the shell solution and the full 3D solution, and the effects of the transition are highlighted. Per saperne di più
This benchmark model simulates a graded heterojunction using the thermionic emission formulation for the charge transfer over the junction. It shows the additional contribution to the current density from the quantum tunneling effect across the potential barrier, using the WKB ... Per saperne di più
This model calculates the current and charge characteristics of a floating gate Electrically Erasable Programmable Read-Only Memory (EEPROM) device. A stationary study demonstrates the effects of varying the charge stored on the floating gate by computing Current-Voltage curves as a ... Per saperne di più
This example provides a walkthrough on how to simulate the basic radiated emission of a printed circuit board and its immunity response from outside noise. First, when one of the microstrip lines is excited, the crosstalk to an adjacent printed line and the radiated field, through an ... Per saperne di più
