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.
In this example, the natural frequencies of a double hat beam are studied. The beam is made of two thin steel plates, joined together by spot welds along the flanges. The Spot Welds feature sets up multiple mesh-independent connections between the shells. Per saperne di più
This example illustrates the modeling of a tensegrity table. The table is made of two rigid bodies connected through a central wire and four outer wires. Two cases are analyzed. In the first case, the top of the table is loaded with vertically downward acting load of varying magnitude. ... Per saperne di più
Gradient-based optimization is an efficient way of computing better values for many control variables. This example optimizes diameters of individual members in a truss structure such that the structure becomes stiffer without adding mass to the structure. The structure will be only be ...

Topology optimization is associated with extreme design freedom which can yield extreme performance. The designs can be easier to manufacture by using milling constraints, at some cost to the performance. This example considers the case of a torsion sphere which is known to feature a ...

Beam theories are well-developed for slender structures with homogeneous materials and isotropic cross-sections. The traditional beam theories do no apply to beams made of different materials in the cross-section. Therefore, a homogenization-based numerical model is needed to compute ... Per saperne di più
This model demonstrates the ability to simulate Multibody Dynamics in COMSOL. It comprises a multilink mechanism that is used in an antique automobile as a gearshift lever. It was created out of curiosity to find out how large forces are on the individual components. The model uses ... Per saperne di più
In this multibody dynamics model of a simple counterweight trebuchet, a parametric sweep is used to study throwing distance as function of the sling length. For more details on performing a multibody analysis of a counterweight trebuchet, see this blog post: What Is the Physics Behind a ... 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
Find the optimal cross section areas of trusses in a structure given a prescribed set of limitations and a clear objective. The structure is made up of trusses which are elements that can only sustain axial forces. Per saperne di più
When estimating the parameters of a multiphysics model, both experimental noise and modeling uncertainties will contribute to corresponding uncertainties in the final parameters estimated. In this verification example, we demonstrate the new Variance functionality in the Parameter ... Per saperne di più
