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.
This example exemplifies how curve fitting can be performed in COMSOL Multiphysics®, and how this can be applied to your modeling. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Curve Fitting of Experimental Data with COMSOL ... Per saperne di più
This model solves the Boltzmann equation in the two-term approximation for a background of molecular and atomic hydrogen. Electron mobility and source terms are computed by suitable integration of the electron energy distribution function over electron impact cross sections. Per saperne di più
These examples demonstrate how to use a job sequence to perform a programmatic sequence of operations, including solving; saving the model to file; and generating and exporting plot groups, results, and images. In the blog post associated with these files, "How to Use Job Sequences to ... Per saperne di più
This model studies a small orifice located in a duct. The transmission and reflection coefficients of the system are computed in the presence of a bias flow using the linearized Navier-Stokes equations. For certain frequencies the transmission coefficient shows amplification (T>1). This ... Per saperne di più
This tutorial demonstrates the use of the Heat and Moisture Flow predefined interface for the modeling of heat transfer and moisture transport in a turbulent air flow, with the quantification of evaporation and condensation on surfaces, and the automatic handling of the associated latent ...

In this example a thin curved membrane is built and solved using the Shell interface. This model is a widely used benchmark model denoted the Scordelis-Lo roof. The computed maximum z-deformation is compared with the value given in Proposed Standard Set of Problems to Test Finite ... Per saperne di più
This model shows how to define a frequency-domain analysis of heat transfer. The 3-omega method uses the Cahill's equation to approximate the thermal conductivity of a sample from the measured temperature of a metal strip placed on top of it and subject to oscillating heating. The 2D ... Per saperne di più
To understand the risk of coagulation and blood clot formation in an abdominal aortic aneurysm (AAA), modeling and simulation can be used to study the blood flow through the AAA. In this example, blood is modeled as an Oldroyd-B fluid. While this is a generic example, if instead using ... Per saperne di più
Ultrahigh Molecular Weight (UHMW) Polyethylene is a material commonly employed in knee and hip joint replacements. The “small punch test” is designed to assess mechanical properties using very small samples, such that because of their size they can directly be explanted. This example ... Per saperne di più
In this example, an SF6/argon plasma reactor at moderate pressure is studied using a global model. The heavy species heat equation is included. Parametric sweeps for input power and argon mole fraction are computed. Per saperne di più
