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.
Sensitivity analysis is an efficient way of computing the gradient of an objective function with respect to many control variables. This example uses the pitch and yaw in the top of a truss tower as objective functions. It shows how to compute the sensitivity of these angles with respect ... Per saperne di più
The example Stiffness Analysis of a Communication Mast’s Diagonal Mounting in the COMSOL Multiphysics Model Library shows how you can modify a 3D CAD model to improve its performance. In that case, the applied changes were based solely on the analyst’s experience with similar structures. ... Per saperne di più
This tutorial models the acoustic behavior of a loudspeaker driver mounted in a bass reflex enclosure. The enclosure, sometimes called the cabinet, alters substantially the sensitivity and radiation characteristics of the loudspeaker and it is why it is usually considered part of the ...

A solidly-mounted resonator (SMR) is a piezoelectric MEMS resonator formed on top of an acoustic mirror stack deposited on a thick substrate. This tutorial shows how to simulate an SMR in 3D. In this example, the eigenmodes were computed with varying number of particles attached to the ... Per saperne di più
This tutorial illustrates how to use the Uncertainty Quantification (UQ) functionality to answer questions regarding sensitivity and reliability of a flow reactor with thermal decomposition. The tutorial investigates what uncertainties in parameters dominates the survival of a nutrient ... Per saperne di più
This example demonstrates how to apply the Uncertainty Quantification (UQ) Module in COMSOL Multiphysics to analyze the performance and reliability of a simple resistor. Small variations in material properties, geometry, and manufacturing processes can significantly impact the resistance ... Per saperne di più
A spherical hydrophone consisting of a PZT ceramic, a coating material, and a cable is modeled in 2D axisymmetry. The Receiving Voltage Sensitivity (RVS) is computed for an incident plane wave and compared to an analytical solution from the reference for an ideal spherical hydrophone. ... Per saperne di più
A line array of eleven spherical hydrophones embedded in a neoprene coating is modeled in 3D. The sensitivity of the array is analyzed with regard to varying angles of incidence of the background pressure field. The array directivity function is computed and compared to the analytical ...
