FIM failed and At time=0.000E+00 the integrator failed to proceed.

Hello, I have built a three wheeler(2 wheels front and 1 wheel rear) on MotionView. I have checked the model and it has no errors. However, when I try to run an analysis such as constant radius turn, the solver fails and gives an error saying "At time=0.000E+00 the integrator failed to proceed". There is also another warning saying FIM failed. Can somebody help me out and tell me why this is happening, it would be much appreciated. I have attached a snippet of the error message for reference.

Please see the other topic created above yours.

So I had made a few changes to my model and started to run a double lane change test. While the MotionSolve did not show any error...on reviewing the animation I noticed that the model did not run a double lane change. I have attached a video of how the vehicle behaved. Can you please tell me what could have caused this? If you look closely at the starting of the video, you will see that the two wheels turn in opposite directions and the powertrain also moves around randomly.

Hi Pramod - A couple of points from my recent observations:

1) Questions like these should please be submitted as a support ticket, since they are specific to debugging your model. Without looking at the log file or model, it would be quite difficult or impossible to troubleshoot this.

2) It appears both your question and model are related to the other post from Vinayanand. Since you are from the same organization (apparently), please reply in the other post.

Thanks,

Ananth
