Hello can we use gulp for liquid system?
Yes, though it’s more designed for solids as the focus is on optimisation and lattice dynamics.
then for liqiud system, what steps should i follow ?
is there any example or tuitorial?
As I mentioned, GULP is really focused on solids & so there is no specific tutorial for liquids. However, if you know about simulating liquids (I’d recommend reading Allen and Tildesley’s book Computer Simulation of Liquids) then you’ll see that there are examples of MD which can be applied to any phase of matter.
