[gmx-users] interface

[mohammad agha]

Dear Mark,

Thank you very much from your reply.
I see a box that the half of it consists of water and another half of box is void, but when I run md.mdp for production simulation all of water molecules dispersed in total of box and I don't see interface and total of box filled by water.

Can you help me to construct the air/water interface, Please?

Best Regards
Sara

You need to use visualization software and see if the configuration
    looks like you intend it to look. You certainly don't have an
    air-water interface if one of them is vacuum.
