I'm working with a protein in water and I used periodic boundary conditions in three dimension. At first the initial system was minimized, then I followed Justin's protocol. The system was equilibrated in a first stage nvt for 1 ns and in a second stage npt for 1 ns (with restraints). Then the production stage had been done with 100ns.
When I visualize the trajectory results in vmd, I have a problem with the adsorption layer. During the production trajectory, water molecules had spread very much and actually no adsorption happened. The size of the box increases a lot in the beginning of the pvt equilibrated stage (it was 341 nm³ and it becomes 351nm³) and I can't understand that. Why are the water molecules spreading so much? Why don't they constitute an adsorption layer? Any help would be appreciated.
