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.
Light Detection And Ranging (LIDAR) is used extensively in self-driving cars to perform the quantitative ranging of the surroundings obstacles. The LIDAR system consists of a laser beam which gets broadened using a MEMS mirror with a particular horizontal and vertical field of view ... Per saperne di più
This model of a two-story house can be used to examine a contaminant leak and the subsequent contaminant dispersion that occurs due to convection and diffusion. Airflow and recirculation within the home are dependent on vent placement, and flow velocity may also vary at each vent. ... Per saperne di più
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
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
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
These example models demonstrate using the Image to Curve add-in, which is included in COMSOL Multiphysics®. One example shows a simple structural analysis. An image of an H-beam is imported to a work plane and then extruded. A distributed load is applied to the beam's top ... Per saperne di più
In a polymer electrolyte membrane water electrolyzer cell, hydrogen and oxygen gas is produced by electrolysis. The hydrogen and oxygen compartments are separated by a polymer membrane, that also acts as electrolyte. This introductory tutorial computes the ohmic and activation losses in ... Per saperne di più
This slide deck introduces and demonstrates the modeling capabilities for crystallization and precipitation processes in COMSOL using the Size-Based Population Balance interface and Precipitation in Fluid Flow coupling feature released in 6.3. Per saperne di più
This document explains how to install and run COMSOL Multiphysics® and COMSOL Server™ with Amazon Elastic Compute Cloud™ (EC2™). This requires that you have first acquired a Floating Network License (FNL) or COMSOL Server License (CSL) from COMSOL. The license manager ... Per saperne di più
The Helmholtz filter is a popular technique for imposing a minimum length scale in structural topology optimization, but certain applications also call for a maximum length scale. This model demonstrates how to achieve this using an extra PDE filter. Per saperne di più
