You can use the Moving Mesh or the Deformed Geometry interface to implement wrapping of a CAD part around one axis. This model demonstrates both how to implement this wrapping, as well as how to subsequently mesh the surrounding volume around the deformed part. A more detailed ... En savoir plus
The process of filling a water balloon is a vivid example for the interaction of fluid pressure and a nonlinear structural material. This model demonstrates how straightforward a FSI simulation model is set up in COMSOL. En savoir plus
When you are working with foreign CAD or ECAD data, such as files in the STEP, GDS, or IGES file formats, or any of the other supported formats, you may think that you need to re-import a new CAD file and start your modeling over from scratch if you want to study a change in size or ...

This model illustrates the working principle of a passive electrodynamic bearing. An electrically conducting rotor rotating in a magnetic field produced by a permanent magnets induces eddy currents on the conducting rotor. The eddy currents, in turn, produce a magnetic field that opposes ... En savoir plus
This series of models demonstrates how to do advanced electric machine modeling with COMSOL Multiphysics® — in 2D, 2.5D, and full 3D with end effects included. It investigates the performance of a Permanent Magnet Synchronous Motor, as is often used in modern electric vehicles. ... 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 tutorial model shows a system consisting of a Helmholtz resonator on the side of a main duct. The resonator volume is partly filled with a porous material. The model computes the reflection, transmission, and absorption of the system. Thermoviscous losses are included in the model ... En savoir plus
The Magnus effect explains the curl that soccer players can give the ball, resulting in the enjoyable goals that we can see in every FIFA World Cup™. This model looks at the Magnus effect in the laminar and turbulent flow regimes for transient and stationary flows. It also discusses ... En savoir plus
This example exemplifies how to model thermal curing using the base package of COMSOL Multiphysics. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Modeling the Thermal Curing Process". En savoir plus
Multiscale modeling is a challenging issue in modern simulation. This occurs when there are vastly different scales in the same model. For example, your cell phone is approximately 10 cm, yet it receives GPS information from satellites 20,000 km away. In these models we examine several ... En savoir plus
