Hello,
I have some questions about fix wall/reflect command. I create a simulation box:
region box block -60 60 -60 60 0 84
region gong block -30 30 -30 30 0 32
create_box 1 box
create_atoms 1 region gong
and I want to bound the simulation with walls in Z direction and the boundary of the wall is
-60<x<-30&-60<y<-30,(X and Y direction have no walls,only Z direction has walls).
I use the fix wall/reflect command like this:
fix 1 all wall/reflect zlo 32 zhi 52
but how to limit the boundary of the wall in X and Y direction?
I really appreciate for your help~

you cannot.
wall/reflect really only makes sense,
if it covers entire faces of the simulation
cell. if you want to put an obstacle into
the path of your simulated particles,
use non-moving particles for it.
axel.
Or create a region that obstructs particles
via the fix wall/region command.
