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.
A thin-walled container made of rolled steel is subjected to an internal overpressure. As an effect of the manufacturing method, the out-of- plane direction has a higher yield stress than the other two directions. Hill’s orthotropic plasticity is used to model the difference in yield ... Per saperne di più
This model shows how to combine different types of material nonlinearity, such as creep and elastoplasticity. In this specific example you will perform a stress and nonlinear strain analysis on a thick cylinder under a nonproportional loading: an initial temperature increase followed by ...

Several mass–spring–damper models have been developed to study the response of a human body where mass, spring, and damper elements represent mass of different body parts, stiffness, and damping properties of various tissues. In this example, a lumped model of a human body having five ... Per saperne di più
Coriolis flowmeters, also known as mass flowmeters or inertial flowmeters, measure the mass flow rate of a fluid traveling through it. It makes use of the fact that the fluid's inertia through an oscillating tube causes the tube to twist in proportion to the mass flow rate. Typically, ... Per saperne di più
This model illustrates how to perform prestressed eigenfrequency and frequency response analyses in a contact problem. A circular plate is squeezed between two thicker plates. The peak of the prestressed frequency response analysis is compared with the prestressed eigenfrequencies as ... Per saperne di più
In this model, we use the Pressure Acoustics, Boundary Elements physics interface to analyze the acoustics of a generic head and torso simulator. This is a manikin head used to do standardized measurements for hearing aids, mobile phones, and headphones. The model showcases some ... Per saperne di più
This is a model of a simple photoacoustic (or optoacoustic) resonator. A pulsating laser heats a gas causing expansion and contraction and thus creates pressure waves. Such devices are used as sensors for measuring material parameters of the gas inside the resonator. The resonance ... Per saperne di più
This tutorial model shows a system consisting of a Helmholtz resonator on the side of a main duct. The resonator volume is partly filled with a porous material. The model computes the reflection, transmission, and absorption of the system. Thermoviscous losses are included in the model ... 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 example demonstrates the modeling of a sandwiched composite blade made up of carbon–epoxy, glass–vinylester, and PVC foam materials. Three different methods are used to model the sandwich composite structure: Layerwise theory, Equivalent Single Layer (ESL) theory, and a multiple ... Per saperne di più
