<div>Well-beloved Professor Blaha,</div>
<div> Thank you very much for your detailed explain.I absolutely know the essence.About the following two problems,will you give me some suggestions?</div>
<div> <font color="#550055">1) Are there other means to determine the coordinates of the plane for ploting the electron density except using the software XcrysDen? </font></div>
<div> </div>
<div> 2) When calculating the electron density plots after performing the calculations of DOS or Bandstructure,errors will always come.The solution I adopt to resolve that problem is to continue running the last cycle of scf. But that way is very
time-consuming.Are there other better means to solve that problem? </div>
<div> Thank you very much.<span class="q"><span></span></span></div>
<div> Best regards.</div>
<div> Yours sincerely,</div>
