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 model computes the fluid flow, charge transport and electric potential in an electrostatic precipitator. Based on the resulting fields, particles of different diameter are fed into the device and the transmission probability is computed. As expected, the separation efficiency shows ...

Interfacial failure or delamination in a composite material can be simulated with a cohesive zone model (CZM). A key ingredient of a cohesive zone model is a traction-separation law that describes the softening in the cohesive zone near the delamination tip. This example shows the ... Per saperne di più
Diffusion-induced stress in lithium-ion battery electrode materials can occur as a result of compositional inhomogeneities during lithium intercalation in the host material particles. These stresses are important since the electrode host material can undergo significant volume changes ... Per saperne di più
In this study, the compressible turbulent flow through a supersonic ejector is modeled using the High Mach Number Flow interface in the CFD Module. Ejectors are simple mechanical components used for a wide range of applications, including industrial refrigeration, vacuum generation, gas ... Per saperne di più
The model has its emphasis on heat transport in a very small heat exchanger that is commonly used in the field of microelectromechanical systems (MEMS). In this case, it might be a reactive processes that needs heating. The heat exchanger itself is constructed by stacking several ... Per saperne di più
This tutorial shows how to include local nonlinear effects when simulating the acoustics of an exponential horn. Nonlinear effects become important when an acoustic horn is used for high amplitude signaling. The Nonlinear Acoustics (Westervelt) Contributions feature available for the ... Per saperne di più
This is a model of a simple thermoacoustic engine that includes a thermal stack to convert thermal energy to acoustic energy. The model is set up using two approaches: 1) Using a linear perturbation (acoustic) approaches solving the fluid motion with the Thermoviscous Acoustics, ... Per saperne di più
In this example, the structural integrity of a cylinder made by a fiber composite is assessed both at the macroscale and at the microscale level. Along with macroscale analyses, structural composites need microscale stress and failure analyses to identify the critical constituents in ... Per saperne di più
This model shows how to implement an anisotropic, incompressible, hyperelastic material for modeling soft collagenous tissue in arterial walls. The hyperelastic material model implemented is based on the articles: Holzapfel, G. A., Gasser, T. C., & Ogden, R. W. (2000), A new ... Per saperne di più
When electrical energy is converted into mechanical work in an electrical motor, the "wasted" energy that causes device heating is usually referred to as loss. The ratio of useful work to input energy, or the efficiency of the motor, is an important property for the overall energy ... Per saperne di più
