Suppose I have a simulation box that the substrate is made of Copper and Argon atoms on the surface. Also, there is a cubic box of Copper atoms among the Argon atoms. that I want to delete some of the Copper atoms in order to build a T-type shape. My problem is when I use the below code, Argon atoms around the cubic box are deleted, too.
region D1 block 0 42 0 90 19 30 units box
delete_atoms region D1
Before the above code, I have specified Cu and Ar atoms by grouping them as below:
group Ar type 1
group Cu type 2
How can I delete Copper atoms in region D1 without deleting Argon atoms?
Thanks a lot.
