How Neper decides the cell size?

[danishTUE]

Hi Romain,

I have a general query:

In a tesselation command, where the number of cells, domain size and diameq are all provided to Neper (for example discussed in: [https://github.com//discussions/233#discussioncomment-799268], how does it decide the size of the cells?

The script in the above example is:
neper -T -n 100 -domain "cube(48,6,12)" -morpho "diameq:1,1-sphericity:lognormal(0.145,0.03)" -reg 1

Regards,

Danish

Generally speaking, when both the number of grains and the diameq are provided, the diameq input is considered relative. When -n from_morpho is used, then the diameq input is considered absolute.

In your case, you'll get 100 cells, all of the same size. -n 100 -morpho "diameq:2,1-sphericity:lognormal(0.145,0.03)" would produce the same tessellation.

This is explained in -morpho.
