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 Monte Carlo simulation of flow in a turbomolecular pump can be greatly simplified if the mean radius of the blades is much greater than the spacing between them. Under these conditions, the rotating blades of the pump can be approximated as an infinite row of blades having only ... Per saperne di più
This model analyzes Joule heating and thermal expansion in a bond wire in an LED. Its purpose is to estimate the temperature increase and the resulting mechanical stresses in the bond wire due to thermal expansion. The magnitude of these stresses can be used to assess the risk of fatigue ... Per saperne di più
Interfacial failure by delamination or debonding can be simulated with a Cohesive Zone Model (CZM). This example shows the implementation of a CZM with a bilinear traction-separation law. It is used to predict the mixed-mode softening onset and delamination propagation in a composite ... Per saperne di più
This simple model demonstrates how to use the Semiconductor Optoelectronics interfaces to model a simple GaAs PIN diode structure. Both the stimulated and spontaneous emission in the semiconductor are accounted for. The corresponding absorption of the light and the associated change in ... Per saperne di più
This model demonstrates how to compute satellite temperature over multiple orbit periods by coupling Orbital Thermal Loads to Heat Transfer in Solids. The direct solar, albedo, and Earth infrared thermal loads are computed over a single orbit, and are periodically repeated over multiple ... Per saperne di più
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
This alternative version of the Tubular Reactor app demonstrates how computational speed can be significantly increased by using a surrogate model instead of a full finite element model. A surrogate model is a simplified, computationally efficient approximation of a more complex and ... Per saperne di più
