[gmx-users] freezegroups

[Bert de Groot]

Hi all,

anyone recently tried to freeze a group in one dimension?

with the following setup:

freezegrps               = ions   rest
freezedim                = N N Y  N N N

my "ions" group wildly moves, including the z-direction (which I thought
I had frozen). As a check, I tried:

freezegrps               = ions   rest
freezedim                = Y Y Y  N N N

which indeed freezes the group completely, so the rest of the setup seems
ok. What do I need to do to freeze this group in the Z-direction only?

cheers,

Bert
