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 tutorial models an ICP reactor by solving plasma fluid type equations fully coupled with the homogeneous and time-independent electron Boltzmann equation in the classical two-term approximation. The approximated Boltzmann equation is solved for each position of space and is coupled ... Per saperne di più
A microwave circulator is a multiport device in which a wave incident on Port 1 is coupled only into Port 2; a wave incident on Port 2 is coupled only into Port 3; and so on. Circulators are used to isolate microwave components, for example, to couple a transmitter and a receiver to a ... Per saperne di più
Simulation of Maxwell’s equations in the time domain is useful if the objective of the analysis is to observe a transient phenomenon, to find the time it takes a signal to propagate, or if the materials being modeled are non-linear with respect to the electric or magnetic field strength. ...

This example demonstrates a benchmark test showing that Electric Currents in Layered Shells physics interface can be used to obtain the same results as when the model is solved with the Electric Currents interface based on a solid 3D structure. Per saperne di più
This model demonstrates how to use topology optimization with milling constraints to design a metalens that focuses a single wavelength to a point. This involves transferring the optimized results to another component so the result can be verified using an explicit geometry ... Per saperne di più
The External Material functionality makes it possible to program your own material models for cases when the built-in material models are not sufficient. For structural mechanics, you have the possibility to either completely define the material model in a domain, or to add an inelastic ... Per saperne di più
This tutorial demonstrates how to model a gyroscope based on the birdbath resonator gyroscope (BRG) design. The BRG is a type of Coriolis vibratory gyroscope (CVG) invented at the University of Michigan as a navigation-grade gyroscope in the mm-scale. This tutorial shows how the ... Per saperne di più
Uncertainty Quantification (UQ) is used to study the effect of manufacturing variation on the performance of Piezoelectric Energy Harvester. This tutorial shows how UQ studies are specified for a frequency domain study that calculates the energy harvester's power output. Per saperne di più
This example of a dipole antenna array demonstrates a cost-effective analysis using the Boundary Element Method (BEM). When dealing with a large array made of metallic radiators, the Finite Element Method (FEM) would necessitate greater computational resources. The simulation results ... Per saperne di più
The model utilizes a dedicated mesh refinement study, Frequency Domain RF Adaptive Mesh, which dynamically refines the mesh in the region of interest. For the Application Library model Microstrip Patch Antenna, it increases the mesh resolution around areas with high field variations. The ... Per saperne di più
