Hi Janaka,

>using "initSize?
peri3dController uses periodic boundary conditions on an aligned block. The
initial sphere packing is created by periodic (means using periodic boundary
conditions) triaxial compression from randomly placed spheres placed in a block
(cell) with __initSize__ dimensions. This dimensions is then reduced by the
compression, so the block is smaller then initSize.
>2. When I change "initSize" and radius in

No. This only means, that saved packing does not satisfies conditions of
current simulation (and is rejected) and new packing is creating.

initSize is Vector3(x,y,z) where x,y,z are initial dimensions of periodic cell,
so it is not cylindrical..
