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 tutorial demonstrates how a lumped model of a MEMS transducer can be derived from its FEM model. It includes an FEM model of a capacitive micromachined ultrasonic transducer (CMUT) and the corresponding lumped model created using the Lumped Mechanical System (LMS) interface. The ...

This is a benchmark model for flexible multibody dynamics. This model simulates the dynamic behavior of a planar four-bar mechanism when one of the joints has a defect. The out-of-plane motion in the mechanism, caused by the defect in the joint, is compared with the results from the ... Per saperne di più
This model demonstrates how a nonlinear equation system can be setup to solve for the eigenfrequencies of a symmetric laser cavity. The model uses the bidirectional formulation of the Electromagnetic Waves, Beam Envelopes physics interface. The computed eigenfrequencies are verified with ... Per saperne di più
Modeling curing is important in a wide variety of applications such as for devices utilizing polymer materials, rubber materials, plastics, and concrete. Curing is usually an exothermic reaction. In the current example, curing of butyl rubber is studied in a 3D mold for an automotive ... Per saperne di più
To understand the risk of coagulation and blood clot formation in an abdominal aortic aneurysm (AAA), modeling and simulation can be used to study the blood flow through the AAA. In this example, blood is modeled as an Oldroyd-B fluid. While this is a generic example, if instead using ... Per saperne di più
This tutorial illustrates how to use built-in variables and operators, for the evaluation of the bulk temperature along a geometry like a channel, a pipe or a chimney, in a nonisothermal flow in 2D and 3D. The bulk temperature may be needed to compute the heat transfer coefficient for an ... Per saperne di più
In this example, monotonic and cyclic triaxial tests are simulated using the Hardening Soil Small Strain material model. The model captures the effects of small strain stiffness and hysteresis under cyclic loading. The stress-strain relationship matches the hyperbolic curve reported in ... Per saperne di più
A radome minimizes losses and improves radiation characteristics of an antenna through its design. The structure can be optimized to minimize the transmission loss and also designed to improve radiation characteristics including antenna directivity and side lobes. Shown in the model is ...

In complex mechanical systems, it can be challenging to find an optimal (or even good enough) solution only through engineering insight or trial-and-error procedures. Using mathematical optimization methods can then be an efficient path to a better design. In this example, a link ... Per saperne di più
A 3D model is used to simulate the cooling of a bevel gear from an austenitic state. Phase material properties and phase transformation data are imported into the model. The final phase composition and the residual stress state are computed. Phenomena such as thermal strains, phase ... Per saperne di più
