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.
In a diode or a transistor, when a p-n junction is reverse-biased (the p-side is connected to a lower potential than the n-side), ideally, no current should flow. However, due to minority carriers (electrons in the p-side and holes in the n-side), a small current, known as the reverse ... 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
In this example, phase transformation data and phase material properties are imported from JMatPro, and used to compute CCT curves. Dilatometry curves (axial thermal strain) are computed across a range of cooling rates. Per saperne di più
This example demonstrates how to set up text files to use when preprocessing models that contain hundreds of parts. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Automate Model Preprocessing with the Application Builder". Per saperne di più
Mechanical precession prevents bicycle pedals from falling off. The model captures this effect using a multibody dynamics simulation together with a contact analysis. A friction coefficient is associated with the contact in order for the model to capture the effect. Per saperne di più
Freefrom optics has generated renewed interest due to advances in fabrication and manufacturing technology. In this Application Library example, we are going to look at a specific design called the Alvarez lens where two complementary conic surfaces are shifted laterally with respect to ...

Intended as a tool for early proof of concept in capacitive touchscreen device development, the Touchscreen Simulator app evaluates a simulated capacitance matrix as well as the electric field norm. The app computes the capacitance matrix of a touchscreen in the presence of a human ... Per saperne di più
This example shows how to model the behavior of a thermostat where a delay in its reaction has been implemented. A more detailed description of the phenomenon, and the modeling process, can be seen in the blog post "How to Implement a Delay in Your Thermostat Simulation". Per saperne di più
This example demonstrates an app that utilizes the LiveLink™ interface for Inventor® to run simulations on CAD designs. Per saperne di più
This tutorial shows how to simulate coupled heat and moisture transport in a wall. The wall is modeled considering an air flow between interior and exterior varying with time. The 1D model is the third benchmark test defined in HAMSTAD-WP2 Modeling for the validation of numerical ... Per saperne di più
