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 shows how to set up self-contact for a coil spring. As the spring is compressed by a vertical force applied to one of its ends, it comes into to contact with itself and starts to rotate. En savoir plus
In this model, a turbocharger supported on two floating ring bearings is studied. The film forces on the ring cause it to rotate within the bearing. In steady state, the ring rotates at a constant angular speed and the torque on the ring due to the inner and outer films are balanced. ... En savoir plus
This model simulates the mechanism of a differential gear used in cars and other wheeled vehicles. A differential allows the outer drive wheel to rotate faster than the inner drive wheel during a turn. This is necessary when a vehicle turns in order to allow the wheel that is traveling ...

Chemical vapor deposition (CVD) is a process used to grow thin films on substrates. In this CVD example, metal inserts for machining tools are coated with titanium nitride (TiN). The titanium nitride layer improves the wear resistance of the metal inserts by increasing the hardness, ... En savoir plus
Crimping is the plastic deformation process used to form an electrical joint between a stranded conductor and a terminal. The process involves complex multi-surface contact, including self-contact, as the terminal sleeve is plastically deformed around the wire strands. This example ... En savoir plus
This model simulates the mixing of two types of grains in a rotating drum with baffles. The effect of the number of baffles on the mixing is demonstrated by varying the number of baffles in the drum. This model also demonstrates how to build and run a model method that evaluates the ... En savoir plus
This model exemplifies how the rate of steel corrosion in an oil platform increases over time due to build-up of a resistive film on the sacrificial anodes, formed by reaction products. The model also includes secondary current distribution electrode kinetics on the protected steel ... En savoir plus
This tutorial shows how to clean an imported CAD geometry using Geometry Cleanup. This helps to improve the mesh and reduce the total number of elements. En savoir plus
This app demonstrates the following: Multiple tabs in the ribbon Geometry parts and parameterized geometries Parts and cumulative selections can be used to automatically set domain and boundary settings in the embedded model Adding or removing geometry parts with different geometrical ...
