<DIV id=RTEContent> <DIV>Dear all,<BR>I am a beginner with Wien2K. <BR>These are my questions:<BR></DIV> <DIV>1.<BR>I want to calculate the surface of Fe. This is the structure information of the slab:<BR>5.416713 5.416713 35.147408 90.000000 90.000000 90.000000<BR>atom position:<BR>Fe1 0.00000 0.00000 0.00000<BR>Fe2 0.50000 0.50000 0.92294(-0.07706) <BR>Fe3 0.50000 0.50000 0.07706<BR>Fe4 0.00000 0.00000 0.84589(-0.15411)<BR>Fe5 0.00000 0.00000 0.15411 <BR>Fe6 0.50000 0.50000 0.76883(-0.23117) <BR>Fe7 0.50000 0.50000 0.23117</DIV> <DIV>But,the file Fe.outputs showd that :</DIV>
<DIV>PGBSYM: SPACE ! GROUP DOES NOT CONTAIN INVERSION</DIV> <DIV>Why didn't the wien find the INVERSION?</DIV> <DIV> </DIV> <DIV>2.<BR>How to define the VZERO in the cell theoretically.</DIV> <DIV> </DIV> <DIV>3.<BR>Since SO couples spin-up and spin-dn states, they are no longer separable.<BR>But,I still got the file case.energysoup and case.energysodn.<BR>Why are the spin-up and spin-dn states still separable? </DIV> <DIV> </DIV> <DIV>4.<BR>What dose the output information mean?<BR>such as</DIV> <DIV>0.000u 0.010s 0:00.07 14.2% 0+0k 0+0io 175pf+0w </DIV> <DIV> <BR>Best Regards</DIV></DIV><p>
