8.7. Nested full dislocation loop
To create an array of nested full dislocation loops in a BCC single crystal sample,
Step 1:
Use the tool in subdirectory tools/Bcc to creat a BCC single crystal sample:
bcc_reg.lmp, use the shell script in subdirectory tools/para_file_nested_loop to create the parameter file:para_file;
Step 2:
Open terminal, run the following command:
1CryDisGen para_file bcc_reg.lmp
Parameter file
Content of the para_file:
1 Region
2 -x 1 0 0
3 -y 0 1 0
4 -z 0 0 1
5 -lat 3.303
