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 illustrates how to use a reduced order model to compute the response of a structure subjected to three simultaneous loads having independent time histories. Reduced order models provide an efficient way to analyze problems within linear structural dynamics. Per saperne di più
In this 2D tutorial, a test sample consists on one side of an isotropic material and on the other side of a heterogeneous anisotropic material (a transverse anisotropic zinc crystal). Elastic waves in the sample are excited by a point-like force. The model is solved with the Elastic ... Per saperne di più
The model performs a static analysis on a piezoelectric actuator based on the movement of a cantilever beam, using the Piezoelectric Devices predefined multiphysics interface. Inspired by work done by V. Piefort and A. Benjeddou, it models a sandwich beam using the shear mode of the ... Per saperne di più
In this tutorial, the vibrational behavior of a small aluminum plate with four waveguide structures is analyzed. This is an example of a structural component located in a device where elastic waves are propagating, like a smart speaker, an electric motor, or a MEMS device. The plate can ... Per saperne di più
This example is inspired by a classic bridge type called a Pratt truss bridge. You can identify a Pratt truss by its diagonal members, which (except for the outermost ones) all slant down in span-wise direction towards the bridge’s center. All the diagonal members are subject to tension ... Per saperne di più
In this example, wear of the friction material in a disc brake is studied. Quasistatic friction forces are prescribed from simple kinematic considerations. The geometry of the brake pad is continuously updated to account for the material removal due to wear following the well-known ... Per saperne di più
Many piezoelectric materials are ferroelectric. Ferroelectric materials exhibit nonlinear polarization behavior, such as hysteresis and saturation at large applied electric fields. In addition, the polarization and mechanical deformations in such materials can be strongly coupled due to ... Per saperne di più
This example illustrates how to perform eigenfrequency and static analyses of a ladder frame structure for a light truck. Important modeling strategies are described. For example, how to convert a solid geometry to a shell model, how to make different types of connections, and how to ... Per saperne di più
In this example, the homogenized elastic and viscoelastic properties of a particulate composite are computed based on the individual properties of elastic particles embedded in a viscoelastic matrix. Periodic boundary conditions are applied to a unit cell of the particulate composite ... Per saperne di più
This is a benchmark model for a plane stress problem. The accuracy of the computed stress concentration is evaluated, and a mesh convergence study is performed for different element types. Per saperne di più
