*can't upload images for some reason.
While running a harmonic balance configured like this:
1. Run transient - Decide automatically.
2. Run Envelope tstab - no.
3. 1 Tone - fundamental freq. is LO.
11 harmonics.
oversample factor = 4
freqdivide Ration for Tone1 = 1
For random points - tstab outputs wrong results - for example a DC circuit has it's output on the wrong voltage.
while running regular transient (in Cx) I get the right results for all points.
sometimes HB tstab gets it right.
what am I doing wrong?
