As a major supplier of automobile components, Metelli S.p.A. (Cologne, Italy) designs and manufactures brake parts, engine parts, transmission components and water pumps for OEMs as well as for the aftermarket.

Our R&D team has been using modeling software for a decade, but a few years ago we ran into a situation where the software we had been using was inadequate. We then found that COMSOL Multiphysics could handle the job - and in the meantime, we have successfully used COMSOL in an increasing number of projects.
Upgrading From a 2D FEM Tool

We first turned to COMSOL to study the magnetic field in an inverse electromagnetic clutch, which works with a floating disk that is attracted by a magnetic field generated by a permanent magnet; the mechanism is then disengaged through a coil. This project had produced some prototypes designed using a 2D FEM tool. However, we felt the need for a 3D FEM tool both to check the correctness of the simplifications introduced in the 2D model and to be able to manage complex 3D geometries. We chose COMSOL with the AC/DC Module due to good agreement between the model and experiment, which meant that no changes were required to start manufacture of the clutch pre-production samples. We subsequently used COMSOL to examine how the magnetic field flux flows through the steel parts because if this is insuffcient, there is no separation between the parts, and the clutch won't work.
