How to generate different numbers of grains in different layers. see the schematic. Thank you!

Use a multiscale cell file:

scale2:

1 5
2 10
3 15
4 15
5 8

neper -T -n "from_morpho::msfile(scale2)" -morpho "lamellar(w=0.27,pos=start,v=(1,2,0))::voronoi" -dim 2 -o d
neper -V d.tess -datacellcol "scaleid(1)" -print img

Thanks! How to make the grains in each layer obey different distributions? such as normal, lognormal.

Use a multiscale cell file, but for -morpho:

scale2b:

1 diameq:normal(1,0.1),1-sphericity:lognormal(0.15,0.03)
2 diameq:normal(1,0.2),1-sphericity:lognormal(0.15,0.03)
3 diameq:lognormal(1,0.3),1-sphericity:lognormal(0.15,0.03)
4 diameq:lognormal(1,0.5),1-sphericity:lognormal(0.15,0.03)
5 diameq:lognormal(1,0.7),1-sphericity:lognormal(0.15,0.03)

neper -T -n "from_morpho::msfile(scale2)" -morpho "lamellar(w=0.27,pos=start,v=(1,2,0))::msfile(scale2b)" -dim 2 -o d
neper -V d.tess -datacellcol "scaleid(1)" -print img
