Description
Hi,
Some investigation insight to share:
The model fails for a wrong value of SaturatingInductance1.Lact at start time=0, computed by:
10: SaturatingInductance1.Lact=DIVISION((SaturatingInductance1.Lzer - SaturatingInductance1.Linf) * atan(DIVISION(SaturatingInductance1.i, SaturatingInductance1.Ipar)) * SaturatingInductance1.Ipar, SaturatingInductance1.i) + SaturatingInductance1.Linf
As SaturatingInductance1.i is 0 at start time, the original equation would yield to 0 = 0 (so its pretty useless for initial system) and the initial equation to a division by zero. If we just use the start value of SaturatingInductance1.Lact, the results are correct.
