Thanks very much! April 24, 2017 at 5:39 pm #2610 mathiasKeymaster That basically means that the simulation tuned close to unstable. In such cases the results are not really reliable. THerefore we add this code to stop the simulation. Best Mathias April 25, 2017 at 3:34 am #2611 lesmodelMember Dear Mathias, Thanks for you reply. How do we determine this threshold value, that is 0.3 here. April 25, 2017 at 6:52 am #2612 mathiasKeymaster From experience, thats it.
