<div>Dear all,</div>
<div> </div>
<div>I was trying to fit/optimize some parameters of an emperical potential using DFT calculation</div>
<div>results. I got stuck while using the post-processing code.</div>
<div> </div>
<div>It is related to "plot_num" of the pp.x input file. In the manual, I found three values related</div>
<div>to potential:</div>
<div> </div>
<div>1=total potential V_bare +V_H+V_xc</div>
<div>2=local ionic potential</div>
<div>11=the V_bare+V_H potential</div>
<div> </div>
<div>Now what I want is the "classical electrostatic energy or Coulombic potential". I searched</div>
<div>the achive of this discussion list a bit and could not find the answer. I also read the source</div>
<div>code and could not sort it out. I am wondering if it is possible at all to seperate the Coulombic</div>
<div>contribution from the total potential?</div>
<div> </div>
<div>Thanks in advance!<br>-Peter<br> </div>
