Dear,
Recently I have tried to make a simulation of a sphere impacting on a plate, but I failed to get a satisfactory result. Before applying a velocity on the sphere, the system was first minimized using the conjugate gradient method, and then thermalized to a temperature of 300K and equilibrated at the temperature. My question is that why the system becomes chaotic after equilibrium. The attached file is my input script in lammps.
I am waiting for your advice.
Thank you very much.
