Flow Past a Cylinder The following model examines unsteady, incompressible flow past a long cylinder placed in a channel at right angle to the oncoming fluid. The cylinder is offset somewhat from the center of the flow to make the steady-state symmetrical flow unstable. The simulation time necessary for a periodic flow pattern to appear is difficult to predict. A key predictor is the Reynolds number, which is based ... Heat Sink This model is intended as a first introduction to simulations of fluid flow and conjugate heat transfer. It shows you how to: Draw an air box around a device in order to model convective cooling in this box, set a total heat flux on a boundary using automatic area computation, and display results in an efficient way using selections in data sets. Permanent Magnet As an example of a magnetostatic problem, consider how to model a horseshoe-shaped permanent magnet. One way is to treat the entire magnet as a ferromagnetic material, where the two end sections are defined as being pre-magnetized in different and opposite directions. Laser Heating of a Silicon Wafer A silicon wafer is heated up by a laser that moves radially in and out over time. In addition, the wafer itself is rotated on its stage. The incident heat flux from the laser is modeled as a spatially distributed heat source on the surface. The transient thermal response of the wafer is shown. The peak, average, and minimum temperature during the heating process is computed, as well as the ... Effective Diffusivity in Porous Materials Transport through porous structures is usually treated using simplified homogeneous models with effective transport properties. This is in most cases a necessity, since the typical dimensions of the pores and particles making up the porous structure are several orders of magnitude smaller than the size of the domain that is to be modeled. This model introduces the concept of effective ... Bracket - An introduction to structural mechanics modeling These models are used for an introduction to structural mechanics modeling using the structural mechanics module. The following features are introduced: - The Fundamentals: A Static Linear Analysis - Parametric study - Including Initial Strain - Modeling Thermal Expansion - Adding Rigid Connector - Adding Spring Conditions - Modeling with the Shell Physics Interface - Transient Analysis - ... Optical Scattering by Gold Nanospheres This model demonstrates the simulation of the scattering of a plane wave of light by a gold nanosphere. The scattering is computed for the optical frequency range over which gold can be modeled as a material with negative complex-valued permittivity. The far-field pattern and losses are computed. Parameterized Shell-and-Tube Heat Exchanger Geometry Shell-and-tube heat exchangers are commonly used in oil refineries and other large chemical processes. In this model, two separated fluids at different temperatures flow through the heat exchanger, one through the tubes (tube side) and the other through the shell around the tubes (shell side). Several design parameters and operating conditions influence the optimal performance of a shell and ... Two-port Piezoelectric SAW Device This tutorial shows how to model surface acoustic waves in time domain. The 3D modeling geometry represents a 128 degree YX-cut lithium niobate substrate. The SAW device has two ports. The metallic electrodes are modeled as perfect conductors using boundary conditions. The geometric dimensions such as size of substrate, the gap between the ports and the number of inter-digitated electrodes ... Fluid-Structure Interaction This model demonstrates how to set up a fluid-structure interaction problem in COMSOL Multiphysics. It illustrates how fluid flow can deform solid structures and how to solve for the flow in a continuously deforming geometry. The Fluid-Structure Interaction (FSI) multiphysics interface combines fluid flow with solid mechanics to capture the interaction between the fluid and the solid structure. ... 1 - 10 of 799 First | < Previous | Next > | Last Contactez-nous Essayez le logiciel Informations produit Produits Grille de spécifications Grille de spécifications CAO Types de licence Configuration requise COMSOL Software License Agreement (PDF) 5.1 Release Highlights Release History Exemples et Galeries Galerie vidéo Galerie cas utilisateurs Application Gallery Articles techniques et présentations Ressources COMSOL News Magazine Multiphysics Simulation Magazine Introduction to Application Builder (PDF) COMSOL Server Manual (PDF) Introduction to COMSOL Multiphysics (PDF) Explorer la Galerie Ressources Multiphysics Cyclopedia Événements Workshops Webinars Formations Conférence COMSOL 2015 Calendrier des événements Société Contact A propos de COMSOL Presse Carrières Partenaires Consultants Certifiés Support Centre de support Vos cas de support Base de connaissances Téléchargement produit Mises à jour produit Communauté Blog COMSOL Forum de discussion Échange de modèles COMSOL Access France Toggle Language Selector Login Privacy Policy Trademarks | © 2015 by COMSOL Inc.
