Local bond order parameters of 2624 atoms at 5K (quenched)

The configuration is 2624 atoms at 5K minimized by conjugate gradient method. The criterion of coloring atoms according to local bond order parameters is (sequentially):

structure rule color symbol
icosahedral Q6>0.3 && W6<-0.12 Dark Red Cu
fcc Q4>0.16 && W4<-0.13 Golden Au
hcp Q4<0.12 && W4>0.10 Green Cd
other else Gray Ag

Interestingly, there have no atoms with icosahedral local structure (except several trivial surface atoms).

In order to see internal structures clearly, up to 3 surface layers have been cut off.
