Time domain study of inductance in a planar square coil

Please login with a confirmed email address before reporting spam

Hi,

I have been trying to solve a planar square coil in the time domain and I keep getting the error Failed to find consistent initial values. Matrix has zero on diagonal. Last time step is not converged. The coil excitation is given using V_peaksin(2pif*t) and any time step in the stationary step2 seems to get solved just to fail in the transient analysis. Any idea what I could be missing? I know this model can be solved easily in the frequency domain the reason I want to solve it in time domain is I am working on a multiphysics analysis where I combine it with solid mechanics so I need todo a time domain analysis.
