mesh error in the resolution of the moving system

Good morning all,
I always encounter a problem when solving my simulation system. which consists of several permanent magnets which rotate around a common axis (like a rotating machine) in order to create induced currents on a fixed metal plate and even the shapes of the induced currents.
the simulation stops after a few seconds in the remeshing phase because there is a variation of the geometry as a function of time (the magnets make movements) the error displayed is:

Meshing by inserting nodes has aborted
Remeshing of Mecha. Sets impossible on current time step
Remeshing of Mecha. Sets impossible on previous time step
DDVPPN  -> Coordinates of node 4274 is not equal to coordinates of point 105
DDVPPN  -> Failed.
PBEPVF_2 -> failed
PBCEVL_4 -> failed
PBCEVL_3 -> Failed
PBERES_3 -> failed
FL5RE4  -> Command not executed correctly
FL5ERS  -> failed
executeAlgo -> failed

 

I tried several attempts, by different meshes of the system, and the results remain the same (always the same problem).
Please explain to me why and how to overcome this problem, despite that the checks before the simulations of the geometry, the mesh and the physics of the system are good.
thanks in advance everyone
