uniform size

[kittygg]

How can I achieve the filling of 3D crystals with uniform diameter and good sphericity within the layered structure, and fix the interlayer spacing in a cube. The following code seems not to work.

neper -T -n "from_morpho::from_morpho" -reg 1 -mloop 2 -domain "cube(100,100,200)" -morpho "lamellar(w=10,v=(0,1,-1),pos=start)::diameq:lognormal(5,0.1),1-sphericity:lognormal(0.1,0.03)" -morphooptistop "::val=.1" -o dd
