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.
Tutorial example of a Erlang SEIR model for the epidemic of COVID-19. The model is validated against data from China, Sweden, and the US. Parametric estimation is done using the reported deaths over time. The tutorial investigates the impact of social distancing on the progress of the ... Per saperne di più
This model demonstrates how to optimize the charging profile of a battery using gradient based optimization. The optimization solver minimizes the time required for charging the battery from 0% to 90% state of charge, while at the same time constraining the amount lithium inventory lost ...

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 ...

A waveguide filter is designed using shape optimization by moving and scaling rectangles in the geometry. The irises of the initial geometry are optimized to ensure good bandpass response and out-of-band rejection, while maintaining the double mirror symmetry. The EGO optimization solver ...

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
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
Inverted elements can prevent large deformations for shape optimization. This model demonstrates how this problem can be circumvented using export/import of the geometry and a model method. The technique is demonstrated on a benchmark problem from topology optimization, where the ... Per saperne di più
This model demonstrates 3D topology and shape optimization for an extruded geometry. This can be achieved using equation-based modeling and extrusion operators. The model considers stiffness maximization of a beam subject to a constraint on the mass, but the method can be used with any ... 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
The model shows how to estimate the Young's modulus and Poisson ratio based on a tensile test. The test measures the tensile force and the radial displacement. Typical numerical values of these quantities differ with around 10 orders of magnitude. Using a maximum likelihood strategy ... Per saperne di più
