Generating twin and multiple twinning in a grain

[PengWei97]

Dear Neper experts,

I am currently using Neper to generate microstructures with different features. I am interested in creating a microstructure that includes a twin or multiple twins within a grain. I have studied the #401 dialogue in the forum, and I have used the command
neper -T -dim 2 -n "10::msfile(n_msfile)" -morpho "gg::msfile(morpho_msfile)" -o d
to generate a microstructure. However, the resulting microstructure is not what I expected, as shown in the attached figure.

I am wondering if anyone can provide me with guidance on how to introduce twins into my microstructure using Neper. I would greatly appreciate any advice or suggestions on how to accomplish this.

Thank you in advance for your help.

Sincerely,

wei

See: https://neper.info/doc/neper_t.html#cmdoption-morpho

You want to both specify a variable width in your width file, as well as a planar normal to control the spatial orientation.

Thank you so much for your help and suggestions regarding this question on how to introduce twinning in a microstructure generated using Neper. I am happy to inform you that I have successfully addressed this issue by configuring "lamellar(w=0.1:0.02:0.08:0.02:1.0,v=(1,-0.5,0),pos=start)" in the script.

Once again, thank you for your invaluable help.
