Simulation of a "Small" Collision

[Joey_Chen]

@SweetPeasHub Why does setting the User-defined Output Steps help the solver from converge instead of setting Plotting Grid or Polynomial Order?

Thank you for your kindly reply, sir. 

For better convergence in the User-Defined Output Steps, should I choose Automatic or User-defined steps?

better user-defined steps, for example 0, 0.1, 0,2 ... 1
