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.
Superlattice Band Gap Tool
The Superlattice Band Gap Tool model helps the design of periodic structures made of two alternating semiconductor materials (superlattices). The model uses the effective mass Schrödinger equation to estimate the electron and hole ground state energy levels in a given superlattice ... Per saperne di più
Mechanical Modeling of Bentonite Clay
In this example, the Extended Barcelona Basic Model (BBMx) is used to model oedometer, uniaxial swelling, triaxial, and constrained swelling tests on bentonite clays in order to recover the hydromechanical characteristics of the soil samples. There is a good qualitative agreement ... Per saperne di più
Bulk temperature evaluation
This tutorial illustrates how to use built-in variables and operators, for the evaluation of the bulk temperature along a geometry like a channel, a pipe or a chimney, in a nonisothermal flow in 2D and 3D. The bulk temperature may be needed to compute the heat transfer coefficient for an ... Per saperne di più
Maximizing the Eigenfrequency of a Beam
This model demonstrates how to design a beam without low Eigenfrequencies by combining the Density Model feature in the Topology Optimization interface with the Stationary Then Eigenfrequency study step. Per saperne di più
Thermally Induced Creep
Creep is an inelastic time-dependent deformation which occurs when a material is subjected to stress at sufficiently high temperature, say 40% of the melting point or more. Experimental creep data (using constant stress and temperature) often display three different types of behavior ... Per saperne di più
Modeling of a Differential Microstrip Line
A differential line is composed of two transmission lines excited by two out-of-phase signals. This configuration is known to be useful to enhance signal-to-noise ratio. This example shows how to set up the differential microstrip lines using TEM type ports. Per saperne di più
Helical Static Mixer
This app demonstrates the following: Geometry parts and parameterized geometries Dark theme Material appearance visualization with environment reflections Report generation for both Microsoft® Word and Microsoft® PowerPoint Options for setting different mesh sizes Improved graphics ...

Two-phase Flow in a Polymer Electrolyte Membrane Fuel Cell
In a polymer electrolyte membrane fuel cell (PEMFC), water is produced at the cathode. The cell is also fed with water vapor via the inlet gas streams, in order to keep the polymer electrolyte membrane humidified. If the water partial pressure in the gas phase exceeds the vapor ...

Circuit Extractor
One of the objectives of electromagnetic simulation is often the extraction of lumped quantities that can be used in electric circuit simulations. The Circuit Extractor add-in offers an easy way of directly converting the result of electromagnetic simulations into an Electric Circuit ... Per saperne di più
Negative Streamer in Nitrogen
Streamers are transient filamentary electric discharges that can develop in a nonconducting background in the presence of an intense electric field. These discharges can attain high electron number density and consequently a high concentration of chemical active species that are relevant ... Per saperne di più
