Hi all,
I am facing a problem in constraining the crystallographic water molecules 
during invacuo simulation. Even after including the oxygen atom numbers 
in the .top file for position restrain (given below), the dynamics is going 
the same way as it was without positoion restrain. Please Help me out of 
this.
