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 simulates the dynamics of the shock absorber used in a landing gear mechanism of an aircraft. It analyses the stresses, as well as the heat generated in the landing gear components due to the energy dissipated in the shock absorber. A prismatic joint, with spring and damper, ...

In many structural dynamics applications, some components are stiff compared to the supporting structure. Such a stiff part will only contribute to the dynamic properties of the structure through its mass and moment of inertia. It is then possible to reduce the model size significantly ...

Surface plasmon-based circuits are being used in applications such as plasmonic chips, light generation, and nanolithography. The Plasmonic Wire Grating Analyzer application computes the coefficients of refraction, specular reflection, and first-order diffraction as functions of the ... Per saperne di più
This model simulates the shape evolution of a microconnector bump over time as copper deposits on an electrode surface. Transport of cupric ions in the electrolyte occurs by convection and diffusion. The electrode kinetics are described by a concentration dependent Butler-Volmer ... Per saperne di più
This model deals with the stability of a plate with an edge crack that is subjected to a tensile load. To analyze the stability of existing cracks, fracture mechanics theory can be utilized. A commonly used parameter in fracture mechanics, used to predict if a specific crack will cause ... Per saperne di più
This example demonstrates how to model the temperature distribution in a battery pack during a 4C discharge. The pack is constructed by first coupling two cylindrical batteries in parallel. Six parallel-connected pairs are then connected in series to create the full pack. (This is also ... Per saperne di più
Steel structures immersed in seawater can be protected from corrosion through cathodic protection. This protection can be achieved by an impressed external current or by using sacrificial anodes. The use of sacrificial anodes is often preferred due to its simplicity. This example models ... Per saperne di più
This tutorial demonstrates how an electrical circuit model of a MEMS resonator can be derived using the Parameter Estimation feature. The model is a modified Butterworth-Van Dyke circuit created using the Electrical Circuit interface and represents a Thin-Film Bulk Acoustic Resonator ... Per saperne di più
This model treats the free convection and heat transfer of a glass of cold water heated to room temperature. Initially, the glass and the water are at 5 °C and are then put on a table in a room at 25 °C. The nonisothermal flow is coupled to heat transfer using the Heat Transfer module. Per saperne di più
Failure of reinforced concrete structures involves advanced material behavior and interaction between materials. This example demonstrates how to model various stages of the failure of a reinforced concrete beam. The material model includes a coupled damage-plasticity model for the ... Per saperne di più
