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.
HowTo: Using the EC External I-Terminal The External Couplings in the CIR interface has two flavors that can be used. External I vs. U and External I-terminal. The former has two nodes (it represents a differential external voltage measurement) and when coupling to an EC Terminal ... Per saperne di più
The Bessel panel is a way to arrange a number of loudspeakers so that the angular sound distribution resembles that of a single speaker. This model combines five Bessel panels in the same pattern to approximate a purely radial sound field. The speakers are driven with different ... Per saperne di più
Indentation tests are commonly used to evaluate the safety of battery cells by assessing the risk of internal short circuits under external mechanical loads. This example demonstrates how to set up such a test, in which an indenter is pressed onto a battery cell, causing large ... Per saperne di più
Applying an electric field across a suspension of immiscible liquids may stimulate droplets of the same phase to coalesce. The method known as electrocoalescence has important applications, for instance, in the separation of oil from water. To model electrocoalescence, you need to solve ... Per saperne di più
This example of a simple axisymmetric condenser microphone includes all the relevant physics and determines the microphone sensitivity as well as microphone capacitance for the specific simplified microphone geometry and material parameters. It solves a fully coupled multiphysics model ... Per saperne di più
This application shows how a battery cell exposed to a hybrid electric vehicle drive cycle can be investigated with the Lithium-Ion Battery interface in COMSOL. This model predicts the battery behavior to make comparisons of the monitored properties. They can be used to understand the ... Per saperne di più
This app demonstrates the usage of a surrogate model function for predicting the cell voltage, cell open circuit voltage and internal resistance of an NMC111/graphite battery cell undergoing a battery test cycle. The surrogate function, a Deep Neural Network, has been fitted to a ... Per saperne di più
An electrostatically actuated MEMS resonator is simulated in the time and frequency domains. The device is driven by an AC + DC bias voltage applied across a parallel plate capacitor. The dependence of the resonant frequency on DC bias is assessed, and frequency domain and transient ... Per saperne di più
This application illustrates how to model an electric machine, such as a generator, motor, or drive, by exploiting its sector symmetry to reduce the size of the problem. The machine being studied is a simplified electric generator in 3D, based on the geometry used in the generator_2d ... Per saperne di più
This example treats the modeling of electroosmotic flow in porous media. The system consists of a compartment of sintered porous material and two electrodes that generate an electric field. The cell combines pressure and electroosmotic driven flow. The equations that are solved are the ... Per saperne di più
