Adams Car understeer gradient

shriharshaprasad.s

I was trying to plot understeer gradient curve of MDI default vehicle-(Steering wheel angle Vs lat acc)-what I observed is that there is peak at around 3300 mm/s^2 of lat acc. Apparently, this peak is coming in all the vehicle models including subcompact default vehicle. The same is reflecting in the model which we have built ourselves. Ran the entire model in kinematic mode but the peak still appears at that point, we have used default powertrain model and figuring out problem around it.  I was wondering if anyone else has noticed this issue and how to tackle it. Is it an inherit error or something with model/test or solver setting?
