[gmx-users] RE: can gmx be used to simulation NaCl

[Vitaly Chaban]

Tsjerk,
Well, the best way would be AIMD, no doubt.

William,
Look here http://www.mpibpc.mpg.de/groups/grubmueller/start/teaching/vorlesung_computerbiophysik_2004/p4/index.html
for an example how freezing/melting of argon is processed by means of
GROMACS.

TW> Cheers,
