[gmx-users] water density

[Linda]

Hi, all,

	Before gmx-users have disscussed water density to run MD. As David suggested, we can delete some numbers of water to adjust water density. I follow this idea, but when I equilibate system with NPT ensemble, I found the box size was decreased, and the water density decreases. I think the reason is the pressure adjust the density. when I equilibate system with NVT, the water distribution is not equal.There is no water in some space of simulation box. 

Does anyone (David?) have experience on water density? Thanks!
