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.
Nucleate boiling occurs when a liquid is heated by a source hotter than the saturated fluid temperature but with a heat flux below the critical heat flux. In this regime, high heat flux are possible due to the evaporation of the liquid. This model aims to demonstrate the calculation of ... Per saperne di più
You can use assembly meshing to reduce the number of mesh elements in your model, which is especially useful for conjugate heat transfer simulation in cases where the fluid domains can be handled with swept mesh. These models demonstrate how to use form assembly and discontinuous meshes ... Per saperne di più
In a polymer electrolyte membrane water electrolyzer cell, hydrogen and oxygen gas is produced by electrolysis. The hydrogen and oxygen compartments are separated by a polymer membrane, that also acts as electrolyte. This introductory tutorial computes the ohmic and activation losses in ... Per saperne di più
This tutorial demonstrates how to modify a concentration-independent (also known as a secondary current distribution) liquid alkaline water electrolyzer with concentrated electrolyte theory to explicitly resolve local electrolyte and solvent concentrations (thereby creating a tertiary ...

When estimating the parameters of a multiphysics model, both experimental noise and modeling uncertainties will contribute to corresponding uncertainties in the final parameters estimated. In this verification example, we demonstrate the new Variance functionality in the Parameter ... Per saperne di più
This model shows how to model a simple Metal–Insulator–Metal (MIM) diode. The two metal electrodes are defined on each side using the Metal Contact feature. Two studies were performed: one without quantum tunneling across the potential barrier and the other including it, using the WKB ... Per saperne di più
Piezoelectric microblowers are compact, lightweight air pumps with varying applications including electronics cooling and airflow related medical devices. The device consists of a PZT-brass diaphragm and a specially designed housing including a pumping chamber, air inlet and outlet ... Per saperne di più
This model demonstrates 3D topology and shape optimization for an extruded geometry. This can be achieved using equation-based modeling and extrusion operators. The model considers stiffness maximization of a beam subject to a constraint on the mass, but the method can be used with any ... Per saperne di più
Formally known as size separation in vibrated granular materials, the Brazil nut effect (BNE) (and sometimes the Muesli effect) is a phenomenon that causes large grains to separate from small ones and rise to the top of a granular bed under vibrations. This phenomenon can be studied ... Per saperne di più
This model demonstrates the caustic effect produced by a cylindrical mirror. It highlights the advantages of the forward ray shooting method when modeling specular reflections from an external radiation source with the Surface-to-Surface Radiation interface. Per saperne di più
