Error : Failed to find consistent initial values

Hi !

I'm trying to simulate a magnetic dipole in time domain but I'm encoutring an error. The model is fonctional in frequency domain but when I use the time dependent study, the progress window shows that the simulation stucks in the constraint handling/creating multigrid levels step and soon after I get the attached below error message.

I'd be grateful for any kind of help and thanks for you eventual support !
