How to generate a polycrystalline model including two different phases

[huli031805]

Hello Romain,
I wonder how it is possible to generate a polycrystalline model including two different phases similar to the below picture. I would be very grateful if you can share the corresponding code.

Here is an example:

neper -T -n from_morpho::100 -morpho "lamellar(w=0.25,v=(0,0,1),pos=start)::gg,aspratio(3,1,1)" -domain "cube(1,0.3,1)" -morphooptistop "::val=.1" -o CuNb
neper -V CuNb.tess -dataedgerad "0.01/(scale*scale+1)" -print img

To build different tessellations in Cu and Nb, use a multiscale cell file:

n_scale2:

1 100
2 200
3 100
4 200

morpho_scale2:

1 gg,aspratio(3,1,1)
2 gg
3 gg,aspratio(3,1,1)
4 gg

neper -T -n "from_morpho::file(n_scale2)" -morpho "lamellar(w=0.25,v=(0,0,1),pos=start)::file(morpho_scale2)" -domain "cube(1,0.3,1)" -morphooptistop "::val=.1" -o CuNb2
neper -V CuNb2.tess -dataedgerad "0.01/(scale*scale+1)" -print img2
