Hi Ujwal - What is the overall (on-car) steering ratio of this vehicle? What is the circle diameter of the constant radius maneuver? It appears to me that the turning radius of the vehicle might too big in order to be able to negotiate the circle, or the rear axle has lost grip at the limit (oversteer condition). Sharing your model could yield further revelations.

Hello Sir, Thank you for replying.

The rack pinion coupler ratio is set to 6 which gives the overall steering ratio 16.5 .However i have tried to run the tests for different steering ratios ,all of them leading to solver failed status

similarly, i have run the tests for different increased radius of constant radius curve only to get no success.

please have a look at my model

The model appears to not open in MV 2021.2 Can you please create a model archive using File->Export->Model->Check boxes archive and create zip file->Export? We can take a look after and offer suggestions.
