How to create a mixed grain ensemble ?

[ppothana]

I would like to generate tesselation of mixed grain ensemble as shown in figure. Could you please help me with the commands to be used to generate such mixed structures ?

Figure source : (Quey et al., 2011) https://hal.archives-ouvertes.fr/hal-00858028

Such a structure is obtained when there are no seeds on the right side of the domain. It can for example be generated as follows:

1. Generate seed coordinate in cube(0.6,1,1):

neper -T -n 1000 -domain "cube(0.6,1,1)" -statseed x,y,z

2. Generate tessellation is cube(1,1,1) from these seeds:

neper -T -n 1000 -domain "cube(1,1,1)" -morphooptiini "coo:file(n1000-id1.stseed)"

3. Visualize:

neper -V n1000-id1.tess -showcell "y>0.5" -showedge "cell_shown||domtype==1" -print img

Thank you very much.
