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 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
One of the possible formats when working with scanned data is text files with coordinate data created from images for the slices of an MRI or CT scan. This is an example with 3D coordinate files from the cross sections of the different levels of a human head. Each coordinate file ... Per saperne di più
The mass of an aluminum beam is minimized subject to a displacement constraint and a distributed load. The problem is solved using topology optimization with milling constraints. Per saperne di più
The model shows how to calibrate the probability distribution of the Young's modulus and Poisson ratio based on a tensile test. The test measures the tensile force and the radial displacement for different values of the prescribed displacement. The model is based on synthetic data ... Per saperne di più
This tutorial minimizes the mass of a bracket that is synchronized from Solid Edge® via the LiveLink™ interface. There are limits both for the lowest natural frequency, and for the maximum stress in a static load case. The size and position for a number of geometrical features ... Per saperne di più
This example studies heat transfer in a square column. Cold and hot temperature conditions are applied to the boundaries. Due to the symmetry of the problem, the geometry is simplified to half of the square. The temperature field is compared with the analytic data. This example ... Per saperne di più
Buckling is a common failure mode for slender structural components. This model shows how the buckling load of a diagonal brace can be maximized, while constraining the volume of the brace. Per saperne di più
This tutorial illustrates the use of the connecting features in the Heat Transfer in Solids and Heat Transfer in Shells interfaces, to couple them to a Lumped Thermal System interface. The results obtained with the solid and shell models are compared. Per saperne di più
This example shows how to model a FinFET in 3D. The I-V characteristics of the device are simulated. First, the gate voltage is swept to obtain the drain current versus gate voltage plot. Then, the drain current versus drain voltage characteristics are computed for fixed gate voltages. Per saperne di più
Analyzing resonances is essential when designing loudspeakers. Resonances can come from various sources in a loudspeaker, with the diaphragm being a significant one. There are numerous traditional approaches to address diaphragm resonances, each with its own benefits and drawbacks. A ... Per saperne di più
