Dear Wien2k users,<br>
I have questions about the Wien2K force output.<br>
After I run run_lapw -fc 0.01 -p &, the calculation converged, which<br>
means the force in the system should small than 0.01mRy/a.u..<br>
But in end of the scf file, the last interaction gives,<br>
<br>
TOTAL FORCE IN mRy/a.u. = |F| Fx Fy<br>
Fz with/without FOR in case.in2<br>
:FOR001: 1.ATOM 0.000000 0.000000 0.000000<br>
0.000000 total forces<br>
:FOR002: 2.ATOM 0.000000 0.000000 0.000000<br>
0.000000 total forces<br>
:FOR003: 3.ATOM 6.480000 0.000000 0.000000<br>
-6.480000 total forces<br>
<br>
TOTAL FORCE WITH RESPECT TO THE GLOBAL COORDINATE SYSTEM:<br>
:FGL001: 1.ATOM 0.000000000 0.000000000<br>
0.000000000 total forces<br>
:FGL002: 2.ATOM 0.000000000 0.000000000<br>
0.000000000 total forces<br>
:FGL003: 3.ATOM -6.480000000 0.000000000<br>
0.000000000 total forces<br>
:FSUM : Sum of forces Fx,Fy,Fz 0.00000 0.00000<br>
0.00000<br>
<br>
Besides, in the previous two interaction, the force is 1.905.<br>
<br>
TOTAL FORCE IN mRy/a.u. = |F| Fx Fy<br>
Fz with/without FOR in case.in2<br>
:FOR001: 1.ATOM 0.000 0.000 0.000<br>
0.000 partial forces<br>
:FOR002: 2.ATOM 0.000 0.000 0.000<br>
0.000 partial forces<br>
:FOR003: 3.ATOM 1.905 0.000 0.000<br>
1.905 partial forces<br>
<br>
Is the TOTAL force in the last interaction the sum of force in the<br>
cell? The equivalent atom for ATOM3 is 4.<br>
Best,<br>
Hua Peng<br>
