Plate displacement and force due to halbach array

Please login with a confirmed email address before reporting spam

I am working on a problem, where the circular permanent magnets halbach array is rotating using external motors over a Aluminium plate. Due to the flux of time-varying magnetic field, a electromagnetic force is experienced by the halbach array, making it levitate. I am trying to simulate this situation, to calculate the forces acting and the steady-state levitation height of the halbach array. I have tried to simulate it in two ways, first case in which the halbach array is fixed and the aluminium plate rotating with the surrounding region is taken as deformable zone and account for the forces and displacement of plate, and second case in which the plate is rotating at a fixed location and the halbach array inside a deformable region with the forces and displacement of the array. Currently, I have taken the reference from a example problem from application libraries named "electrodynamic_levitation_device". My simulation is running but getting stuck at 4-5% progress. Kindly guide me, I have the attached the .mph files for the both cases.
