Galleria dei Modelli

La Galleria dei Modelli raccoglie un'ampia varietà di modelli realizzati con COMSOL Multiphysics in diversi ambiti applicativi, inclusi quelli elettrico, meccanico, fluidico e chimico. E' possibile scaricare i file .mph dei modelli 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. Per scaricare i file .mph dei modelli è necessario effettuare il login o creare un account COMSOL Access associato a un numero di licenza valido.

Image Import: Homogenized Pore Scale Flow and Thermal Conduction

You can now use image data to represent 2D material distributions or to identify regions with different materials by their color or gray scale. Images used in this way can have many origins such as scanning electron microscope (SEM), computed tomography (CT), or magnetic resonance imaging (MRI). An important application of image import is for easy computation of equivalent volume-averaged ...

How to Use Contour Line in Geometry

This presentation gives instructions on how to export a Contour Plot (single line), re-import it as an Interpolation Curve on a Work Plane in the Geometry, extrude the Work Plane, then Convert to Solid to create two domains separated by the new surface.

Two-port Piezoelectric SAW Device - new

This tutorial shows how to model surface acoustic waves in time domain. The 3D modeling geometry represents a 128 degree YX-cut lithium niobate substrate. The SAW device has two ports. The metallic electrodes are modeled as perfect conductors using boundary conditions. The geometric dimensions such as size of substrate, the gap between the ports and the number of inter-digitated electrodes (IDTs) ...

Electrocoating of a Car Door

This example models electrocoating of paint onto a car door in a time-dependent simulation. The deposited paint is highly resistive which results in lowered local deposition rates for coated areas. A primary current distribution in combination with a film resistance model is used to describe the charge transport in the electrolyte. The model is in 3D and uses an imported CAD geometry.

Solute Band Dispersion in Curved Microchannel - new

This model studies the dispersion of neutral species band through curved microchannel in an Electroosmotic flow (EOF) . Using Optimization module, geometric optimization is carried out to minimize the curve-induced dispersion.The central idea is to parametrically represent the geometry by Bézier curves and these geometric parameters are further treated as optimization parameters in the ...

Loudspeaker Suspension

In this model, the resistance and compliance of the suspension in the Loudspeaker Driver model are computed using a purely mechanical analysis.
