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.
In this tutorial, the acoustic properties of a wax guard are analyzed. A wax guard is a small perforated mesh used to protect the receiver (the miniature loudspeaker in a hearing aid) used for receiver-in-the-ear (RITE) or receiver-in-canal (RIC) hearing aids. Because of the very small ... Per saperne di più
This verification model of nonisothermal laminar flow through a circular tube compares the heat transfer coefficient obtained from simulation with theoretical values based on Nusselt number correlation functions that can be found in the literature. Per saperne di più
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
In modeling of transport by diffusion or conduction in thin layers, we often encounter large differences in dimensions of the different domains in a model. If the modeled structure is a so-called sandwich structure, we can replace the thinnest geometrical layers with a thin layer ... Per saperne di più
Reflective mufflers are best suited for the low-frequency range where only plane waves can propagate in the system, while dissipative mufflers with fibers are efficient in the mid- to high-frequency range. Dissipative mufflers based on flow losses, on the other hand, also work at low ... Per saperne di più
This 2D stationary model computes heat and moisture transport in a wall composed of different hygroscopic materials. A comparison with the Glaser method is given for the temperature and relative humidity solutions. The effect of the use of a vapor barrier is also investigated. 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
A plane electromagnetic wave propagating through free space is incident at an angle upon an infinite dielectric medium. This model computes the reflection and transmission coefficients and compares to the Fresnel equations. Per saperne di più
In general, there are two classes of ventilation: mixing ventilation and displacement ventilation. In displacement ventilation, air enters a room at the floor level and displaces warmer air to achieve the desired temperature. Heating sources in the room can include running electronic ...

This example shows how to set up multiple sandwiched thin layers with different thermal conductivities in two different ways. First, the composite is modeled as a 3D object. In the second approach, the thin domains are modeled with thermal resistors in the Lumped Thermal System ... Per saperne di più
