In a periodic system, there is no such thing as a "center."  There is no 
productive reason to enforce such a restriction during the simulation like this. 
  The molecules are going to diffuse around.  If they are capable of 
interacting, they will do just that over the course of the simulation, 
irrespective of whatever convenient visualization convention you may wish to have.
