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.
A time-varying current induces a time-varying magnetic field. The magnetic field induces currents in neighboring conductors. The induced currents are called eddy currents. In this model, the phenomenon is illustrated by a time-harmonic field simulation as well as a transient analysis, ... Per saperne di più
The sound distribution from a TV in a two-room apartment is computed. The simulation demonstrates the use of the Acoustic Diffusion Equation interface to get a quick and simple estimate of the local sound pressure level. For increased accuracy, an analytical expression for the direct ... Per saperne di più
This model demonstrates two ways of modeling waveguides that support multiple modes. A PML can be used to absorb any modes, or Ports can be explicitly added for each possible mode. Learn more in this accompanying blog post: Modeling Waveguides that Support Multiple Modes Per saperne di più
The following model demonstrates the usage of the Radiative Beam in Absorbing Media interface for computing the heating of semitransparent materials. Specifically, the model analyzes how a Gaussian profile laser beam heats two different semitransparent materials deposited onto a silicon ... Per saperne di più
Prismatic lithium cells are widely used in electric vehicles and battery energy storage systems. This example demonstrates the use of the Lithium-Ion Battery interface for a full 3D prismatic battery equipped with two jelly rolls. The model defines a full so-called Newman model but ...

Coriolis flowmeters, also known as mass flowmeters or inertial flowmeters, measure the mass flow rate of a fluid traveling through it. It makes use of the fact that the fluid's inertia through an oscillating tube causes the tube to twist in proportion to the mass flow rate. Typically, ... Per saperne di più
This tutorial model shows how to model car cabin acoustics using a hybrid FEM-ray approach. The particular example is that of a tweeter located in the dashboard of the car near the windscreen. A FEM based sub-model of the speaker and its immediate surroundings is used to compute a ... Per saperne di più
This model presents the flow noise generated by flow past the so-called tandem cylinder configuration. The test is part of the “First Workshop on Benchmark problems for Airframe Noise Computations”. The tutorial model shows the steps involved in a flow-induced noise simulation in COMSOL ... Per saperne di più
The Thermal Actuator Surrogate Model Application demonstrates how the computational speed can be increased with the use of a surrogate model. This app demonstrates the following: Adjusting input parameters via sliders, with near-instantaneous updates to the solution retrieved from the ... Per saperne di più
In this model, we use the Bioheat Transfer interface to solve the Pennes bioheat transfer equation. The problem is in 1D and formulated to be dimensionless. The results are compared against analytical solutions derived in a journal paper (Ref. 1). A mesh convergence study shows that the ... Per saperne di più
