Molecular Dynamics



	Thanks to all of you who sent suggestions to my recent query
 regarding MD codes for monatomic systems. Some of you pointed out
 that  freezing a liquid is non-trivial. I'd like to get some feedback
 on the possibility of doing something similar in 2d (also suggested
 by one person). In particular :
 	If a graphical interface is developed, will it be possible to
 look at the 2d system in real time as it evolves, i.e. if such a
 system is "quenched" from a "melt", will it go to a
 "crystalline"
 phase?  What I don't know is whether the system will visually appear
 to "crystallize" or whether there will be too much motion even after
 freezing so that in real time the "crystallinity" or particular
 phases may not be obvious.
