Problems with time-dependent on 3D coils

Good afternoon,

I'm trying to study the time-dependent on 3D coils, through the example "Magnetic Field of Helmholtz Coil", in order to observe the inductance in one of the coils through the other. However, the error always appears:

Feature: Time-Dependent Solver 1 (sol6 / t1) Failed to find consistent initial values. Singular matrix.

For mesh-case 0 there are 23726 void equations (empty rows in matrix) for the variable comp1.mf.psi. at coordinates: (), ... and similarly for the degrees of freedom (empty columns in matrix). Last time step is not converged.

From my research, I have observed that it is a common difficulty (the study of the time dependent on 3D coils).

Someone can help me? Please?

Thanks
