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 glass melt is cooled down by radiation to form the final shape. Wavelength dependence of radiative properties is considered in the first study; its effects on the temperature field is emphasized by comparison with results obtained in the second study wherein equivalent (constant) ...

Cryer's problem is a three-dimensional consolidation benchmark. A porous sphere is subjected to a uniform boundary pressure. The pore pressure at the center of the sphere rises due to the Mandel-Cryer effect that is captured by a two-way coupling between Darcy's law and solid mechanics. Per saperne di più
A gray body with a spherical cavity with various opening areas is simulated using the Heat Transfer, Surface-to-Surface Radiation interface. The emissivity for each case is computed and compared with the classical gray body theory. The COMSOL Multiphysics® result agrees very ... Per saperne di più
This model simulates a cylindrical furnace with isotropic scattering. It validates the use of the Discrete Ordinates Method for 2D axisymmetric cases, comparing the results with the highly accurate Monte Carlo method. The setup and reference Monte Carlo values are given in: R .P. Gupta, ... Per saperne di più
This tutorial model compares the results between a domain approach and the Thin Moisture Barrier feature to simulate the moisture transport in a wall with a vapor barrier. The Thin Moisture Barrier feature neglects diffusion, two studies are proposed, a first one where diffusion is ... Per saperne di più
This model demonstrates how to couple the Radiative Beam in Absorbing Media interface to the Radiation in Absorbing-Scattering Media interface. To learn more about this model, see our accompanying blog post “Modeling Absorption and Scattering of Collimated Light”. Per saperne di più
This example shows how to model carbonation, which is a type of sparging. Sparging is a mass transfer process between a gas and a liquid that is common in industry (such as beverage carbonation and photobioreactor applications) and at home (aquarium aeration). In the carbonation model, ... Per saperne di più
Many important processes in the mesoscale can be described by phase-field models. One of the oldest phase-field problems is the spinodal decomposition. Several standardized benchmark problems have been developed by the phase-field community. In this entry, these problems are solved using ... Per saperne di più
This tutorial shows how to simulate coupled heat and moisture transport in a wall. The wall is modeled considering an air flow between interior and exterior varying with time. The 1D model is the third benchmark test defined in HAMSTAD-WP2 Modeling for the validation of numerical ... Per saperne di più
Thermally induced transformations in solids may be modeled by using an Arrhenius law to express the dependence on temperature of the transformation rate. This tutorial model shows how to use the Irreversible Transformation subfeature, available under the Solid feature of the Heat ... Per saperne di più
