The program get stuck when dealing with surface model

[Satinelamp]

I create a surface model, and tried to use supercell to make disorder replacement, but the prgrom got stuck after I execute
supercell -i CdS-110.cif -v 2 -p "*T2:fixed" -p "*T3:fixed" -p "*T4:fixed" -p "*T5:fixed" -p "*T6:fixed" -n r1 -o step1

Here are the log file and cif file I use:
surface.zip

I confirm that the problem exists, but I have a strong feeling that the structure you trying to process can't give you the result you expect. Please check paper (grouping conception) and tutorial to obtain extra information about the supercell input.

My idea is to build a supcell of ZnS which include 108 atoms, and assign the fraction occupation number for the Zn sites(Zn=0.5,Cd=0.5) by hand, and then use supercell program to help distribute the Zn and Cd elements randomly, so I could get a final strucutre.
Is this gonna work?

Certainly, yes. Please check deeply examples in tutorial.
