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 tutorial model, a step thrust bearing is topology optimized to maximize the bearing capacity. A step thrust bearing consists of a stepped bearing surface on which the end of the shaft rotates. The entire assembly is submerged in a lubricant. The shaft collar is assumed to be ...

Electrode balancing is an important factor in the design of lithium-ion batteries. In this model, use the experimental open-circuit voltage of a cell and some basic assumptions, followed by an optimization solver, to find a proper electrode balancing. Get more details in this ... Per saperne di più
This example solves the problem of finding the optimal thickness profile of a flywheel, so that the moment of inertia is maximized without increasing the mass or the maximum stress in the flywheel. Per saperne di più
Compliant mechanisms are attractive due to their simplicity, owing to their lack of hinges. In this model we show how to design a set of compliant pliers using topology optimization. The resulting design is post-processed using shape optimization, where the maximum stress is constrained ... Per saperne di più

Shape optimization with respect to fatigue properties is not supported, but fatigue properties are well correlated with the maximum stress. The model demonstrates how optimization with respect to a p-norm of the von Mises stress can be used to improve fatigue properties without ... Per saperne di più
This model demonstrates 2D topology optimization for the problem of minimum mass subject to a compliance constraint and a stress constraint. The stress constraint is implemented with a P-norm global aggregation function. The stress input to this is interpolated differently than the Young ... Per saperne di più
This is an example of optimal control, where the input heating power to a rod is optimized to give a certain temperature on the outside of the rod. This is where the maximum water temperature occurs, while the minimum occurs at the center. Therefore this problem corresponds to the ... Per saperne di più

This application illustrates a modeling approach for deriving physically consistent simplified models in the Acoustics Module. The approach consists of converting complex sub-components to an impedance boundary condition and otherwise using simple acoustics throughout the COMSOL model. ... Per saperne di più
