[lammps-users] Why did my liquid water become solid

And when I use these three fixs (fix nph, fix langvin and fix nve) together for the same group atoms, I got warning: >"WARNING: One or more atoms are time integrated more than once". I can't figure out why.

Fix nph is an integrator. You should not use it with fix nve. Else
you're integrating the same atoms twice. That's why you
get the warning.
