Hi All,
I am trying to applying a external force on certain atoms which are above z=10A in my unit cell. Group command is static and does not change atoms as time proceed.
Is there any way to apply a force on the all atom, which are above z=10A .
Thanks a lot.

yes. fix addforce allows a region keyword.
the force is then only applied to the intersection
of the group and the region. if you want to only
select by region, just use the "all" group.
