Question regarding fix wall/gran/hertz/history

Sir,

I am trying to put boundaries for my simulation box, but there seems to be an invisible wall between my particles; i.e they bounce off without touching each other. Is there a command page for this? (I am using LIGGGHTS) How do you resolve this issue?

The code I use to set the walls:

fix xwalls1 all wall/gran/hertz/history primitive type 1 xplane -0.1
fix xwalls2 all wall/gran/hertz/history primitive type 1 xplane 0.1
fix ywalls1 all wall/gran/hertz/history primitive type 1 yplane -0.05
fix ywalls2 all wall/gran/hertz/history primitive type 1 yplane 0.05
fix zwalls1 all wall/gran/hertz/history primitive type 1 zplane 0.
fix zwalls2 all wall/gran/hertz/history primitive type 1 zplane 0.1

My region boundaries: [-0.1,0.1;-0.05,0.05;0,0.1]

Much thanks,

Sheng-En Lin

What have those walls to do with the particles not touching? This sounds more like a visualization issue than a simulation problem.

And that fix is a LIGGGHTS add-on, so I would ask the LIGGGHTS
mail list.
