Dear simmerling,
Thanks for your help.
Yes, my system contains crystallographic waters which
fly off into large distances as the temperature
increases from 0K to 300K. Even when the temperature
is fixed at 300K the water molecules fly off. How can
I deal with this problem. Should I impose some
restraints on the water molecules? If so how can I do
that.
thanking you,
