My model in Adams views 2019 works fine most of the end times and steps but says error at the end time 1 and steps 500,700,1000,1100. My guess is that my model didn't converge or cannot solve the motion in these steps. But there may be several reasons behind this as suggested by the Message window. I am interested to know whether it is the model fault ( redundant constraint, small mass, or small inertia) or simply the solver cannot solve the motion at these steps?
