<div>Dear Prof. Blaha,</div> <div>Thanks for your suggestion.</div> <div>after changing Cu1, Cu2,....... to Cu, I got the case.struct file below. </div> <div>I now have 7 inequivalent atoms compared to 13 in the former case.</div> <div>But I am worried. In adsorption calculations is the physics affected </div> <div>if all 12 Cu atoms are inequivalent compared to the case below. I </div> <div>believe with 6 symmetry operations the calculations would be </div> <div>faster as opposed to 1 operation but I don't know if adsorption </div> <div>is the same in using both struct files</div> <div> </div> <div>Thank you</div> <div> </div> <div>============================================================</div> <div>cu111<BR>H LATTICE,NONEQUIV.ATOMS: 7 156 P3m1<BR> RELA<BR> 9.489000 9.489000 34.866000 90.000000 90.000000120.000000<BR>ATOM -1: X=0.00000000
