<DIV>Dear wien2k user,</DIV>
<DIV> </DIV>
<DIV>After I did "run_lapw -i 50 -fc 0.001", the job stoped after 19 iterations, and I got the force as following (only the last few iterations),</DIV>
<DIV> </DIV>
<DIV>:FOR001: 1.ATOM 0.000 0.000 0.000 0.000<BR>:FOR002: 2.ATOM 47.464 0.000 0.000 -47.464<BR>:FOR003: 3.ATOM 0.000 0.000 0.000 0.000<BR>:FOR001: 1.ATOM 0.000
0.000 0.000 0.000<BR>:FOR002: 2.ATOM 47.465 0.000 0.000 -47.465<BR>:FOR003: 3.ATOM 0.000 0.000 0.000 0.000<BR>:FOR001: 1.ATOM 0.000 0.000 0.000 0.000<BR>:FOR002:

0.000 -47.466<BR>:FOR003: 3.ATOM 0.000 0.000 0.000 0.000<BR>:FOR001: 1.ATOM 0.000 0.000 0.000 0.000<BR>:FOR002: 2.ATOM 158.872 0.007 0.012 -158.872<BR>:FOR003: 3.ATOM 0.000
0.000 0.000 0.000</DIV>
<DIV> </DIV>
<DIV>I don't understand which number is the real force on atom 2, -47.466 or -158.872.</DIV>
<DIV> </DIV>
<DIV>I noticed that after I did min_lapw to optimize the internal free coordinates, I did another seperated self-consistent calculation with the optimized coordinates, the resultant forces are different from the ones given by the min_lapw. What's the problem?</DIV>
<DIV> </DIV>
<DIV>Thanks in advance for your reply.</DIV>

<DIV>Best,</DIV>
