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.
At the bottom of an oil well, the pressure and temperature can differ significantly from those at the surface. As the oil mixture flows upward and the pressure decreases, phase changes may occur. At the wellbore inlet, the mixture may already contain both liquid and gas phases. ... En savoir plus
Beam theories are well-developed for slender structures with homogeneous materials and isotropic cross-sections. The traditional beam theories do no apply to beams made of different materials in the cross-section. Therefore, a homogenization-based numerical model is needed to compute ... En savoir plus
Say you would like to simulate a natural material or an arrangement of parts that have some known statistical distribution of dimensional variations. In such cases, you can create a random geometry based on these variations. This model file is an example that demonstrates how to create ... En savoir plus
In semiconductor manufacturing, vacuum chucks are used to rapidly and contamination-free adsorb and secure wafers before processes such as transfer, lithography, and inspection. Traditional empirical design makes it difficult to quantify the effects of groove shape, size, distribution, ... En savoir plus
This model demonstrates how to use a space-time formulation to optimize a heating profile over time. Get an overview in the accompanying blog post Equation-Based Modeling with a Space-Time Discretization. En savoir plus
The electrodes of a lithium-ion battery are porous and consist of an active solid electrode material, a binder, and pores filled with a liquid electrolyte. Expansion of the active material due to lithium intercalation changes the volume fraction of electrolyte-filled pores in the ... En savoir plus
This model demonstrates the filtration of grains of three different sizes as they pass through two vibrating sieves of different hole sizes. En savoir plus
This example of a plasmonic waveguide filter shows that the waveguide rejects the electromagnetic radiation of the wavelength between 1.4 um and 1.6 um, but allows the rest of the wavelength. The silver material can be modeled using the Drude-Lorentz approximation, with ε∞ = 3.7, ωp = 13 ... En savoir plus
This example exemplifies how to optimize the design of a capacitor through optimization. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Changing the Dimensions of a Model Using Shape Optimization". En savoir plus
The model remove details example v63.mph illustrates how to manually add the Remove Details operation and virtual operations to find and remove small details from a model geometry. In the model geometry cleanup example v63.mph, the automatic Geometry Cleanup added Remove Details ... En savoir plus
