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.
The flash method is widely used for measuring the thermal conductivity of a thin sample material that is about the size of a coin. The sample material is submitted to a laser pulse on one of its faces. In turn, the opposite face is heated up by around 1 K. As the pulse is uniform and ... Per saperne di più
This model shows the workflow to define a transfer orbit trajectory with user defined orbit option. The direct solar, albedo, and Earth radiative thermal loads are analyzed during the transfer from low Earth orbit to geostationary orbit. 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 shows how to simulate moisture redistribution inside a wall with capillary active interior insulation. The wall consists of three layers: brick, mortar and insulating material. At the beginning of simulation, there is a sudden change in vapor pressure and temperature at ... 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
This model presents a way to compute projected area using the Surface-to-Surface Radiation interface of the Heat Transfer Module. By computing illuminated area from a set of directions on a discretized sphere, it is possible to interpolate the projected area onto any angle of incidence. ... Per saperne di più
This model is used on "Heat Transfer with Radiation in Participating Media and the Discrete Ordinates Method" to compare quadrature sets used in the method of discrete ordinates. To assess the performance of quadrature sets in complex geometries, results of incident irradiation and ... 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
Basin-type insulators are critical components in Gas-Insulated Metal-Enclosed Switchgear (GIS). During the manufacturing process, the curing of epoxy resin can generate residual stresses that may lead to the formation of cracks in insulators. Over time, these cracks can cause partial ...
