Creating a layered domain?

[behroozkarami]

Dear All,

I need to create a two layered domain ( 2D) in which the top part (subdomain) is grained and the bottom in blank. I was wondering is it possible in Neper? Any ideas are appreciated.

Thank you very much,
Behrouz

neper -T -dim 2 -n "from_morpho::id==1?1:100" -morpho "lamellar(w=0.9,v=(0,1,0),pos=start)::voronoi" -o d
neper -V d.tess -print img

Thanks a lot! That's exactly what I was looking for.
Best regards,

Dear Romain,

Could you please advise me how can I apply statistical distributions option to the top layer?
I want to apply something like -morpho "diameq:lognormal(0.1,0.03),1-sphericity:lognormal(0.145,0.03)" to the grains distributed at the top layer but haven't been able to figure it out yet.

Thank you very much,
Behrouz

You need a multiscale cell file for that:

mymsfile:

1 voronoi
2 diameq:lognormal(0.1,0.03),1-sphericity:lognormal(0.145,0.03)

neper -T -dim 2 -n "from_morpho::id==1?1:100" -morpho "lamellar(w=0.9,v=(0,1,0),pos=start)::msfile(mymsfile)" -o d
neper -V d.tess -print img

Right, thank you so much.
