hello, the system I'm working on seems to have the problem of presenting 
strong forces during the dynamics that finish in the explode of the 
system. Just to clarify  what Xavier (x.periole at chem.rug.nl) wrote, how 
is possible to have a different behavior, even a slightly different 
route, if you start for o point of the dynamics that goes thougth the 
same path that does that has explode out your system. Do you regenerate 
the velocities or something similar? or is more like playing with 
intrinsic round errors of the computer?

Thanks in advance Hector.
