I am getting an error "step size too small", when running a quasi-static simulation (Default steering), Whereas when I run it with dynamic simulation(steering input) - the model works fine. What could be the reason for this? Any suggestions

In general, it is much harder to find a static solution than to do a dynamic simulation. Take for example the simplest possible model: One part, under the influence of gravity. No static exists, but it is very easy to simulate the dynamics (and the result will of course be a constant acceleration of 9.81 m/s^2).

So check that your model is stable, no lose parts that are falling away, or your steering does not over-toggle that could cause an unstable solution. Look at the animation from the dynamic simulation carefully to see if there is anything that does not look as it should.

Thanks, Jesper, I looked into the model, as you mentioned there was toggle issue. Thanks for this pointing it out!
