what possibly reason for "camber , Fz exceeds validity range"?

Hello,
I have full vehicle simulation for handling . During some simulation condition i will get message like followings, otherwise others condition not. Could you tell me , what ist prossibly reason for such kind of warrning?

  • Another observation: Most common occurrences of this is during the Newton-Raphson process of the solution, so it happens before the solution has converged. In those cases it will not affect the final, converged solution.
    But to be sure, plot the normal load (Fz) and camber angle from the simulation. If the plots shows values outside of the fitted range, the solution might not be correct.
