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.
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 ... En savoir plus
Transport which is purely diffusive in nature can be modeled using a Brownian force. This model shows how to add such a force in the Particle Tracing for Fluid Flow physics interface. Particle diffusion in a fluid is modeled with the diffusion equation and the Particle Tracing for Fluid ... En savoir plus
This model shows how to build and solve a radiative heat transfer problem using the Heat Transfer interface. In particular, this 2D model illustrates the use of the surface-to-surface radiation feature. In this model, three surfaces form a cavity. Heat flux is set at two outer ... En savoir plus
This model presents the flow noise generated by flow past the so-called tandem cylinder configuration. The test is part of the “First Workshop on Benchmark problems for Airframe Noise Computations”. The tutorial model shows the steps involved in a flow-induced noise simulation in COMSOL ... En savoir plus
This model illustrates the refraction of light while passing through an optical prism using s– and p–polarized incident Gaussian beams. The prism boundaries are coated with anti–reflection coatings. It also calculates the reflectance and transmittance to analyze the performance of anti ... En savoir plus
Predicting the transport of solutes that move with subsurface fluids is of general interest in environmental engineering and geosciences. Solutes may not only be pollutants but also artifical tracers added to the groundwater for investigation purposes. This model tracks a solute over ... En savoir plus
This is a benchmark model for the 2D axisymmetric formulation of the Electromagnetic Waves, Frequency Domain interface that is available with the RF Module. The problem is to find the resonant frequencies and fields inside an axisymmetric cavity with rectangular cross-section and ... En savoir plus
This tutorial model presents a study of a double-headed streamer in nitrogen at atmospheric pressure. An initial seed of electrons is placed between two electrodes which apply an initial electric field of 52 kV/cm to the gas. A negative and positive streamer propagate toward the ... En savoir plus
There are multiple ways to excite and terminate transmission lines using different types of port and lumped port features. In this example, transverse electromagnetic (TEM) type ports and a via type lumped port are used to simulate two adjacent microstrip lines. One via end is terminated ... En savoir plus
Prevent shaking windows and enhance the sound experience by careful positioning of the loudspeakers in your room. This tutorial analyzes the low frequency response of a living room to the woofer units of two loudspeakers, and solves for the eigenfrequencies of the room. The room geometry ... En savoir plus
