Hi gmx users,
I'm a new Gromacs user. Till now, I can get pretty good simulation of
ice melting to water, but why can't I simulate water freezing to ice?
The .top and .gro files used for water freezing simulation are
generated by ice melting to 310K. I changed the temperature in .mdp file to
230K, but after mdrun, the water was still water, it can't freeze?
How can I get water freezing to ice?
You need a water model that was parametrized to reproduce this
behaviour. One can't expect 5 (or so) parameters to be capable of
reproducing all possible properties of water - especially when you then
use bond constraints to take several of them out of your model.
