Maxwell3D Error
 

I wanted to simulate the movement of steel plates induced by a permanent magnet. Any simulation I try to do it in Transient gives me the same error:

[info] Setup1 : Transient distributing Transient Solver
[error] This design cannot be solved using TDM (Time Domain Decomposition Method). This is because this design may include models using hysteresis, coreloss effect on field, or motionl setup using 'consider mechanical transient'. And the current version of TDM does not support model with using adaptive time stepping, or models using external circuits.
Does anyone know what this is?
I'm new here ... thank you.
