Notez que de nombreux exemples présentés ici sont également accessibles via la Bibliothèques d'Applications intégrée au logiciel COMSOL Multiphysics® et disponible à partir du menu Fichier.
Electrical events, such as an overcurrent or overload, can seriously damage electrical circuits or power lines. To avoid expensive replacements of critical parts, electric switch circuit breakers can be installed. These mechanically interrupt the current flow or surge by moving a plunger ... En savoir plus
In this tutorial, the acoustics of an open-plan office space are analyzed using a wave-based approach in the time domain. An initial pulse is released and the room response is analyzed. Realistic frequency-dependent impedance conditions for the ceiling, carpet, and gypsum walls are ... En savoir plus
In this shape optimization example, the mass of a bracket is minimized by changing the size and position of a number of geometrical objects. The requirements give limits both on the lowest natural frequency, and on the maximum stress in a static load case. This means that results from ... En savoir plus
In this example, a settlement and heave analysis of a shallow foundation resting on an unsaturated soil stratum is conducted with the Modified Cam-Clay and Extended Barcelona Basic soil models. The effect of pore suction due to movements in the phreatic line and the resulting settlement ... En savoir plus
This tutorial introduces the use of topology optimization in acoustics. The goal of the optimization is to find the optimal material distribution (solid or air) in a given design domain, here the ceiling of a 2D room, that minimizes the average sound pressure level in an objective ...

Failure of reinforced concrete structures involves advanced material behavior and interaction between materials. This example demonstrates how to model various stages of the failure of a reinforced concrete beam. The material model includes a coupled damage-plasticity model for the ... En savoir plus
In offshore applications, it is sometimes necessary to quickly seal a pipe as part of the prevention of a blowout. This example shows a simulation, in which a circular pipe is squeezed between two flat stiff indenters until it is almost flat. The model serves as an example of an analysis ... En savoir plus
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 ... En savoir plus
A thermoacoustic engine is a device with no moving parts that can generate acoustic energy from temperature gradients within the engine. It uses the relationship between the movement of oscillating air and the temperature changes in the air compressed and expanded by the acoustic waves. ... En savoir plus
In this example, a torque is applied to the inner edge of a circular annulus-shaped membrane while the outer edge is fixed, resulting in membrane wrinkling. The wrinkling membrane model avoids the equilibrium instability that would be produced by the compressive stresses. The effect of ... En savoir plus
