I hope it helps.</div>

Hi<br>
<br>
can anybody please suggest me. I am studying a system of Ni with 40 atoms<br>
and then i am replacing one Ni with any other alloying elements. I want to<br>
the charge density plot. I have got the charge density by two methods.<br>
1) substituted the alloying element and performed scf through pw.x, and pp.x<br>
2) relax the structure and then performed scf through pw.x, and pp.x.<br>
<br>
what difference should i try to figure out which will suggest the right<br>
method.<br>
<br>
Thanks in advance<br>
