color coded the grain

[asmaaharfoush]

Hello,

I would like to create a tessellation that is color-coded red for small grain, green with medium, and blue for large grain. does neper can help with that? How I can visualize the grain with these colors coding? Also how I can generate three different sizes using the same morpho.

Thanks!

The easiest and more versatile way is to export the cell sizes using -statcell, use this file to create a cell color file, and use the cell color file in -V:

$ neper -T -n 1000 -statcell diameq
$ awk '{if ($1<0.11) print "red"; else if ($1<0.13) print "green"; else print "blue"}' n1000-id1.stcell > cell-colors
$ neper -V n1000-id1.tess -datacellcol "col:file(cell-colors)" -print img

Also how I can generate three different sizes using the same morpho

Not sure what you mean, but if you want the sizes to follow a unique distribution, you can typically use -morpho diameq:lognormal(...), and if you want the sizes to follow different distributions, you can sum these distributions, as in -morpho "diameq:lognormal(0.1,0.035)+0.2*lognormal(0.2,0.070)+0.1*lognormal(0.3,0.105)".

Thank you, that is very helpful!

Professor Dr. Romain, I have generated 3 colors in Neper and when I generate a .msh file and then open it in Gmsh software then the .msh file shows many colors, so I need your suggestions that what should I do for the .msh file to generate the desired colors.
Please have a look at the attachment.
I have used the following commands.

neper -T -n 100 -statcell diameq -reg 1

awk '{if ($1<0.0085) print "red"; else if ($1<0.0095) print "green"; else print "blue"}' n100-id1.stcell > cell-colors

neper -T -n 100 -morpho "diameq:lognormal(1,0.05),1-sphericity:lognormal(0.078,0.03)" -domain "square(0.05,0.1)" -dim 2

neper -V n100-id1.tess -datacellcol "col:file(cell-colors)" -print img100

neper -M n100-id1.tess -elt tri -rcl 0.558 -meshqualmin 1.0

Thank You

Neper does not push colors to the msh file. This is more a Gmsh question...

Thank you Professor Dr. Romain Quey for your kind response.
