Hi Grzegorz,

I would check that the correct options are being used for the 53
(keyopt(1)=4), and for the 124, (keyopt(1)=6.) Do the flux lines and
range of B plotted make sense? Try solving a harmonic. If the R and L
values seem correct for the harmonic and not for the transient, it would
appear to be a problem with the code. If you know R (hand calculated,
at least) and C, you could use a close form solution for the current to
compute an effective L for the current trace from the results.

I've done my model and everything is super. But, just now I want to
replace the stranded coil to the massive conductor, and calculate
resistance and inductance. Unfortunately, I can't do this. RES & IND
values equal zero every substep!!!
Strange, because the current run has got some time-constant L/R. How did
solver compute these values and why I can't obtain theirs? I've
determined the flux (inductance) from MVP but, I must know how did
solver obtain the inductance in order to compensate their parameters of
electric circuit.
