Magnetic field and Electric current physics problem at low frequency

Please login with a confirmed email address before reporting spam

Hi,

I am working on a 3d hemisphere model coaxially centered between two multi turn coils (5cm apart). The whole model is surrounded with a sphere acting as both magnetic as well as electrical insulator.
I will have to excite one of the coils with 1 Am/m2 current to induce eddy current in the hemisphere(having dielectrical properties of human breast) at frequencies 0.01,0.1,1 and 10MHz. In this problem I have used physics controlled normal sized mesh.

The problem is that the solution is not converging in the lower frequencies(0.1 and 0.01MHz).

Can anyone please assist me with this issue ASAP as I'm stuck for a month now? Thank you so much!!!
