Edge properties of multilayer materials

[ranyang123]

When I generated multi-layer materials and mesh using the following command, and imported them into Abaqus, I found that the edges of each layer are shared by two layers, so there are two properties. How can I solve this problem?
neper -T -domain 'square(10,3)' -n "from_morpho::msfile(grainrefine)" -morpho "lamellar(w=1,pos=start,v=(0,1))::voronoi" -dim 2 -o d1 neper -M d1.tess -elttype hex -rcl 0.5 -format inp
grainrefine 1 10 2 10 3 10

Not possible to do in the current version.

I would generate the three slices independently using Neper and paste their meshes externally.
