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.
Diesel particulate filters (DPFs) are designed to remove and filter soot (diesel particles) from the exhaust of diesel engine vehicles. The filters in such systems are typically structured with long, air-filled channels surrounded by a porous medium that retains the soot. Although the ... Per saperne di più
The External Material functionality makes it possible to program your own material models for cases when the built-in material models are not sufficient. For structural mechanics, you have the possibility to either completely define the material model in a domain, or to add an inelastic ... 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
This example describes how to simulate the self-lubricating phenomenon of a liquid lubricant in a journal bearing. A porous bushing is press-fitted to a bearing and saturated with a lubricant. It acts as a reservoir for the redistribution of the thin film of lubricant between regions of ... Per saperne di più
Switched reluctance motors work on the principle of reluctance torque. The stator and rotor will interact to minimize the reluctance for the flux path. This application simulates the behavior of the motor when the stator winding is excited with a step voltage and when the rotor is at a ... Per saperne di più
This tutorial digs deeper into the investigation of rate capability in a battery and shows how the Lithium-Ion Battery interface is an excellent modeling tool for doing this. The rate capability is studied in terms of polarization (voltage loss) or the internal resistance causing this ... Per saperne di più
This app demonstrates the usage of a surrogate model function for predicting the cell voltage, cell open circuit voltage and internal resistance of an NMC111/graphite battery cell undergoing a battery test cycle. The surrogate function, a Deep Neural Network, has been fitted to a ... Per saperne di più
This model simulates an electrodeless lamp with argon/mercury chemistry. The low excitation threshold for mercury atoms means that even though the mercury is present in small concentrations, its behavior dominates. There is strong UV emission from the plasma at 185 nm and 253 nm. The UV ... Per saperne di più
Modeling packed beds, monolithic reactors, and other catalytic heterogeneous reactors is substantially simplified with the Reacting Flow in Porous Media multiphysics interface. This defines the diffusion, convection, migration, and reaction of chemical species for porous media flow ... Per saperne di più
The AC/DC magnetic interfaces support material models defined in external C code. You can access external material functions, written in C code, which have been compiled into a shared library. By writing a wrapper function in C code, you can also use material functions written in another ... Per saperne di più
