Hi,


I have a coil and inside a rod. The rod vibrate with a given frequency.

Knows somebody how could this in Comsol ?

In help are some materials about vibrating membrane but I don't know exactly to particularize for my case.

Thanks,
CR

Hi

you need to tell us wha is driving what: is the coil vibrating from an external force, and then you want to induce some signal in the coil (which needs to have some current flowing someway. Or is it the magnetic filed of the coil that is giving a vibrating force on the rod ?

Sort out your variables, then decide for the physics, and sart with the "driving" force/flux

Good luck

Hi,

The magnetic rod is vibrating inside in a static coil.
Finally I want to calculate the voltage induced in the coil due to variable magnetic fields passing through static coil.
The rod is magnetised.
I used the modules: Magnetic Fields and Electrical Circuit and now I want to vibrate the rod.
I need the Structural Mechanics module to add ?

Probably not. The functionality in the base COMSOL Multiphysics module should be enough for your vibration analysis.
