In my simulation I want to oscillate a wall. I was using a retangular box and oscillating the zplane by the command fix wall/gran + keyword wiggle:
fix id all wall/gran zplane 0.0 2000.0 40.0 0.50 wiggle z 2.0 3.0
Now, I'm using a cylinder container and the command fix wall/gran (fix id all wall/gran zcylinder 6.125 40.0 0.5 wiggle z 2.0 3.0), but it don't function correctly. The wall z don't oscillate. I only modified the geometry (rectangular for cylinder).
Why it happens?
Ah! I'm using the version lammps-17Jul06.
