induction heating by permanent magnets

[EmrisIsBack]

Hello,
I've got a task like this.

let's say there's a cylindrical workpiece (aluminium), there's a system of permanent magnets around it.
The cylindrical workpiece rotates at a angular speed and is subject to eddy currents.

I did this at ANSYS.

One of the approaches in Ansys is velocity effct.
i.e. I can set some rotation speed for this body.
This problem was solved in magnetostatics.


Tell me which solver I need to use in Elmer.

And if it is possible how it can be realized at all.

maybe there's some kind of "body force" or something like that?
I think I need to use MagnetoDynamics2D solver

I'm quite familiar with ansys apdl, but I want to learn how to use Elmer.


Thank you very much in advance.

p.s. I apologize for my bad English

I would work through some of the elmer tutorials to get a feel of the elmer workflow. After that the source code depository has numerous test problems for each solver, there are many for MagnetoDynamics2D, I would study those. Often I am able to adapt a test case to my application.

Hi,

I think you may need a 3D simulation (the MagnetoDynamics module) in order to make this type of analysis with Elmer. A way to introduce velocity effects by having a term of the type v x curl A in the equations (with v and A being the velocity and the vector potential) has not been implemented into the 2D solver.

Best regards,
Mika

I just mention that a term v x curl A has now been implemented into the 2D solver as well (available in the fresh devel version of Elmer).
