Can I use the "lamellar" and "diameq" functions at the same time?

[aksiteray]

I am hoping to create sub-grain with "diameq" function and would like to apply lamellar specifically to each sub-grain, not the entire grain with same lamellar. Is this possible? If so, how it is used?

I know that each can be done individually as thought at "https://neper.info/generation.html#generalities":

$ neper -T -n 200::from_morpho -morpho "gg::lamellar(w=0.02)"
$ neper -T -n 200::1000*size -morpho 'gg::diameq:dirac(1),sphericity:lognormal(0.145,0.03,1-x)'

Yes, you can do 3-scale:

$ neper -T -n 10::100*size::from_morpho -morpho 'gg::diameq:dirac(1),1-sphericity:lognormal(0.145,0.03)::lamellar(w=0.02)'

$ neper -T -n 10::100*size::from_morpho -morpho 'gg::diameq:dirac(1),1-sphericity:lognormal(0.145,0.03)::lamellar(w=0.02)'

Hello Rquey,

Is it possible to use the "diameq" function in the third layer? According to your code, the width of lamella is a fixed value (w=0.02).

Many thanks in advance,

I'm not sure what exactly you want to do, but yes, just put it there.

Hi Rquey,

Okay, in the third layer, I want absolute lamella width(w) to follow a lognormal distribution, rather than having the same lamellar width(w=0.02) throughout the grain. Is it possible? If you are still confused, please let me know.
By the way, please tell me where I can install Neper version 4.2.1-4.

Thanks in advance,
zszAachen

Much obliged! Thank you very much for the response.

Statistical distributions are not supported here, but you could provide the successive values (obtained from the lognormal distribution) as follows (here for a gaussian distribution):

$ gsl-randist 1 100 gaussian 0.01 | awk '{print $1+0.03}' > w
$ more w | tr '\n' ':' > w2
$ neper -T -n from_morpho -morpho "lamellar(w=`more w2`)"
