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.
Example for a geometry sequence to create a ship hull using Loft. The different cross sections are defined using Dimensions and Constraints. Per saperne di più
This example exemplifies how you can export the data from your mesh and results to a text file. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Exporting Meshes and Solutions Using the Application Builder". Per saperne di più
This model analyzes the scattering of a plane propagating modulated Gaussian pulse off a submarine hull. The scattered field and the spatial response are also determined. The model uses the Pressure Acoustics, Time Explicit interface to model this large acoustic model in the time domain. ... Per saperne di più
The homogenized material properties of a composite are computed based on the temperature-dependent properties of matrix and fiber. The homogenized parameters are compared to the analytical values derived from the rule of mixtures. This is an extension of model https://www.comsol.com ... Per saperne di più
In food industries, microwave heating is gaining attention over a conventional heating treatment because of several advantages such as precise process control, speed of heating, fast turn-on and turn-off time, etc. In this model, a high directional Yagi-Uda antenna is used to heat up ...

A radio frequency quadrupole ion trap utilizes a radio frequency quadrupole (RFQ) in order to trap an ion beam. A continuous high energy ion beam is first cooled and converted into a spatially confined bunch, which can then be released with minimal heating of the beam. The device is also ... Per saperne di più
This example demonstrates how to use a parameterized slice plot and animation functionality to export a sequence of images. In addition, the example shows how to use a job sequence to perform a programmatic sequence of operations where the model is first solved and then the image ... Per saperne di più
This model simulates the propagation of a double-headed streamer in nitrogen at atmospheric pressure. Initially, electron-positive ion clusters were introduced between two parallel electrodes, subjecting the gas to a strong background electric field of 52 kV/cm. Subsequently, both the ...

A trimmer capacitor has a variable capacitance. One way of obtaining this is to use parallel facing electrodes with a variable overlap area. In this example, the capacitance can be changed by turning one electrode using a screwdriver. Typically a linear angular response is desired. ... Per saperne di più
