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.
Dielectric Shielding Comparison
The dielectric shielding boundary condition is meant to approximate a thin layer of material with high relative permittivity compared to its surroundings. This boundary condition is available for electrostatic field modeling. This example compares the dielectric shielding boundary ... Per saperne di più
Contact Analysis of an Elastic Snap Hook
In this example, which serves as a tutorial for contact analyses, the insertion of a snap hook in its groove is studied. A linear elastic material model is used. Per saperne di più
How to Generate Randomized Inhomogeneous Material Data
These examples demonstrate how to generate and visualize randomized material data with specified statistical properties determined by a spectral density distribution by using the tools available under the Results node. In the blog post associated with these files, "How to Generate ... Per saperne di più
Convective Flow in a Heat Exchanger Plate
This example models flow in a microchannel heat exchanger by coupling a Laminar Flow interface in 3D to a Pipe Flow interface. By the use of the Pipe Flow interface to model the flow in the microchannels the problem size is significantly reduced. This model showcases the Pipe Connection ... Per saperne di più
Radar Cross Section
This tutorial model demonstrates the use of a background field in an electromagnetic scattering problem. Although this example is a boat hit by a radar, this same technique can be used in any situation where an isolated object meets electromagnetic waves from a distant source. For ... Per saperne di più
Virtual Operations on a Wheel Rim Geometry
This tutorial shows how to perform virtual geometry operations on an imported CAD geometry. These virtual operations, such as form composite entities or ignore entities can help to improve the mesh and reduce the total element number. Per saperne di più
Stress Analysis of an Elliptic Membrane
This is a benchmark model for a plane stress problem. The accuracy of the computed stress concentration is evaluated, and a mesh convergence study is performed for different element types. Per saperne di più
Current Distribution in a Chlor-Alkali Membrane Cell
The chlor-alkali membrane process is one of the largest in industrial electrolysis with the production of roughly 40 million metric tons of both chlorine and caustic soda per year. Chlorine is used predominantly for the production of vinyl chloride monomer, which in turn is used for the ... Per saperne di più
Optimization of a Photonic Crystal for Demultiplexing
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 ...

Quenching of a Steel Billet
A steel billet is quenched in oil from its austenitic state. A 2D axisymmetric model is used to simulate the coupled problem of austenite decomposition, heat transfer, and solid mechanics. During the quenching process, the austenite decomposes into a combination of ferrite, pearlite, ... Per saperne di più
