Does full vehicle simulations needs to have auto tyre entity?

Greetings Everyone!

I merged my front and rear half car suspension models successfully and added flat road with flat event. 

Solver is failing in Static Analysis itself during scripted simulation and when I simulated model for static analysis with Generate animation at each iteration debug option kept on, h3d animation showing front system falling down.

My current model is equipped with auto tire entities at rear and graphic tire entity at front. Does it need to be auto tire entities at both end? Or something else is incorrect? 

I'm attaching both log files here for your reference.

 

Thanks & Regards

    Hey Sudip,

    Yes, you must have an AutoTire entity in order for the tire-road contact to initiate.

    This is why you see half of the vehicle fall through the road surface. 

     

    For more help on vehicle simulations, please see the eLearning for MotionSolve for Vehicle Modelling v2023:

    Hope this helps!
