Parameters

• eventspercycle : the number of collision per sphere per cycle
• N : number of spheres
• initialpf : initial packing fraction
• maxpf : maximum packing fraction
• temp : initial temperature (temp=0 means v=0)
• maxpressure : maximum pressure, one of two stopping criterion
• growthrate : the growthrate of sphere
• various_radius : the various radius of spheres (0.5 means the smallest of sphere is 50% of largest sphere)
