La Bibliothèque d'Applications présente des modèles construits avec COMSOL Multiphysics pour la simulation d'une grande variété d'applications, dans les domaines de l'électromagnétisme, de la mécanique des solides, de la mécanique des fluides et de la chimie. Vous pouvez télécharger ces modèles résolus avec leur documentation détaillée, comprenant les instructions de construction pas-à-pas, et vous en servir comme point de départ de votre travail de simulation. Utilisez l'outil de recherche rapide pour trouver les modèles et applications correspondant à votre domaine d'intérêt. 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.
Many complex fluids of interest exhibit a combination of viscous and elastic behavior under strain. Examples of such fluids are polymer solutions and melts, oil, toothpaste, and clay, among many others. The Oldroyd-B fluid presents one of the simplest constitutive models capable of ...

The drive for miniaturizing electronic devices has resulted in today’s extensive use of surface-mount electronic components. An important aspect in electronics design and the choice of materials is a product’s durability and lifetime. For surface-mount resistors and other components ... En savoir plus
This example describes how to simulate the flow of a thin film of fluid in the gap between two rectangular plates, one of them with a porous facing, when the fluid is squeezed as a consequence of the relative motion between the plates. The model accounts for the ingress and egress of ... En savoir plus
This example demonstrates how to model coupled flow, heat transfer, and structural deformation and stress in a pipeline network. Gravity loads from the pipe and fluid are also taken into account. En savoir plus
This model is a benchmark for three-phase flow commonly used in food processing, pharmaceutical industry, and chemical processing. The results are validated against data reported in the literature. A gas bubble rises through two layers of liquid, a lighter liquid resting on top of a ... En savoir plus
Gas cells have several applications in the design of scientific instruments. A gas cell is used to define a high-pressure region within the instrument's main vacuum system. For example, in this application, note we are designing a high-pressure region 100 mm long, with an operating ... En savoir plus
This example models the transient heating, and final temperature, of a disc brake of a car in brake-and-release sequence. It is important to model the transient heating and the following convective cooling to determine the minimum interval between a series of similar brake engagements. ... En savoir plus
This app demonstrates the following: Using a Java® utility class for combining several waveforms and for playing sound Using tables for presenting results The app allows you to study the design of an organ pipe and then play the sound and pitch of the changed design. The pipe sound ... En savoir plus
This example is a model of a continuous casting process. Liquid metal is poured into a mold of uniform cross section. The outside of the mold is cooled and the metal solidifies as it flows through. When the metal leaves the mold, it is completely solidified on the outside, but still ... En savoir plus
The level set method is well suited for problems with moving boundaries in which the geometry’s topology changes with time. A bubble of oil that travels up through water and finally merges with oil at the top causes this kind of topology change. For problems where the topology is ... En savoir plus
