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

[Tsjerk Wassenaar]

Hi William,

I'm not very sure you can simulate crystallization of salt with
classical MD. In any case, the force field is not parameterized to
reproduce crystallization or melting c.q. the melted state of NaCl.
It's therefore unlikely that it will produce meaningful results. The
best approach :) would be to determine parameters for Na/Cl for this
purpose.

Cheers,

Tsjerk
