How to create a initial model with none amorphous atoms

i create a model but it have some amorphous atoms in the initial state . can you show me how to improve the model ?

There is not enough information here to make any specific suggestions. How did you prepare this system? What is it supposed to represent? Which of the three objects shown is the problematic one? And why does it matter?

I want to show the diamond structure of the model but when i show , it have some amorphous atoms . but i want to create the model with full diamond structure and no amorphous

please help me

Sorry, but when I look at your geometry, there is no “amorphous” group of atoms. All atoms seem to be placed on the provided lattice positions.

Also, the simulation run is rather pointless, since there is no time integration fix.
