Achieving Uniform Grain Sizes in Neper's Multiscale Tessellations Mode

[PengWei97]

Dear Neper experts,

I am currently using Neper's multiscale tessellations mode to generate polycrystalline structures #697. However, I have encountered some challenges in achieving uniform grain sizes. I would greatly appreciate your insights and suggestions on how to address this issue.

Specifically, in the microstructure I generated using the following command, the grains indicate that the distribution is not very uniform，

neper -T -dim 2 -n "10::msfile(n_msfile)" -id 40 -morpho "gg::msfile(morpho_msfile)" -domain "square(10,10)" -o d -ori 

Thank you all in advance for your time and assistance!

Best regards,
Wei

It is because of gg. Change it to specify a custom diameq distribution (and add 1-sphericity):

neper -T -dim 2 -n "10::from_morpho" -id 40 -morpho "diameq:lognormal(1,0.01),1-sphericity:lognormal(0.1,0.03)::lamellar(w=0.25)" -domain "square(10,10)" -o d

(changed ms_file into a standard lamellar tessellation for the example.)
