Inductive coupling, Mesh and convergence problems

Please login with a confirmed email address before reporting spam

Hi,
I am trying to simulate the amount of induced current, in some spring shaped structure which has mutual inductance with another inductor. I want to see how much power I can transfer from the external inductor (second inductor)to the coupled inductor(stent).
to simulate that, I defined two separate springs made of Copper floated in Air.
I used edge current in Magnetic and Electric field module for applying some excitation in the external coil and anticipating to see some induced current in the other spring (the distance between these two is about 5 mm).
unfortunately the Magnetic and Electric field module can NOT solve the problem.
Non of the solvers can't converge and find the magnetic field and induced current.
I let the simulator works for 4 hours to find the solution but no success.

Anyone knows what's the problem?

Regards,
Kamyar
