<DIV id=RTEContent>Dear WIEN2k users,</DIV> <DIV>I am started using WIEN2k about a week ago. I've tried the examples in the manual and they worked fine. I tried to use w2web to initialize a calculation for a Fe(111) surface antiferromagnetic (AFM) calculation. However it asked me to supply ''case.struct_supergroup'' file (after editing case.inst) . I looked at the examples in the directory /SRC_afminput/ but I still can't figure out the supergroup the (111) layers. I have read the text in pg 45 of the UG.Can any user kindly tell me how to construct a supergroup for the case.struct file below. OR how can I generate the file case.inclmopy from afminput and feed it to clmcopy</DIV> <DIV>Thank you very much in advance.</DIV> <DIV>J.
