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.
This example exemplifies how to model applications using the Events Interface where a thermostat is simulated. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Implementing a Thermostat with the Events Interface". En savoir plus
This demonstration app will fit a surface through a set of points using radial basis functions and will write out a COMSOL-format file of a smooth NURBS surface that passes through all of the points. The function describing the surface can also be written to a text file. The point data ... En savoir plus
This example demonstrate the modeling of a plug flow reactor for the synthesis of ammonia in the Haber-Bosch process. The catalytic reactor in this process operates under non-isothermal conditions, where temperature and pressure varies substantially along the length of the reactor, in ... En savoir plus
This example shows how to image the interior permittivity of a box by applying a potential difference on the boundaries of the box. The result is a surface charge density that depends on the permittivity of the medium inside the box. Read about this tutorial model in our blog post "The ... En savoir plus
The purpose of this app is to understand EIS, Nyquist, and Bode plots. The app lets you vary the bulk concentration, diffusion coefficient, exchange current density, double layer capacitance, and the maximum and minimum frequency. Electrochemical impedance spectroscopy (EIS) is a common ... En savoir plus
As an analyte band flows through a curved channel in an electroosmotically driven flow, dispersion of the band occurs due to gradients in the fluid velocity across the channel. These velocity gradients result from differences in the electric field acting at the walls within the curved ... En savoir plus
This example simulates the electrolysis of CO2 on a roughened-Cu cathode surface in a CO2-saturated CsHCO3 electrolyte. It solves for the concentration of dissolved-CO2, Cs+, HCO3–, CO32–, H+, and OH– within the mass-transport boundary layer and accounts for the homogeneous (bi)carbonate ... En savoir plus
In electrosurgery, high-power AC current from a probe is driven into tissue in order to cut and coagulate it. The current causes rapid Joule heating near the tip, and as temperatures reach 100°C, water and blood vaporize and the tissue desiccates, enabling cutting or sealing. This ... En savoir plus
This example demonstrates how to model a variable-angle tow (VAT) laminate in which the fiber orientation varies linearly along the global x-direction, with each layer assigned its own fiber angle. The results obtained using the Layered Shell interface are compared with a full 3D ... En savoir plus
This app simulates sedimentation of particles or agglomerations of particles in a solution. The distribution of particles or agglomerations of particles is taken into account. En savoir plus
