Thank you very much Dear Mattioli Sir , it works.<br><br>Can please give a clue to obtained the Al.pz-bhs.UPF (Al LDA with bhs funtionals essentially NormConversing) pseudopotential as i am very poor to generate it myself and not obtained it in pslibrary. <br>
it's a very bad habit i know but i have no option except taking help at this stage for my research.<br><br>thanks in advanced for your kind help.<br><br><div class="gmail_quote">On Fri, Sep 21, 2012 at 7:45 PM, Giuseppe Mattioli <span dir="ltr"><<a href="mailto:giuseppe.mattioli@ism.cnr.it" target="_blank">giuseppe.mattioli@ism.cnr.it</a>></span> wrote:<br>

You require a very strict convergence threshold on wfcs...<br>
1.0d-7 may be sufficient for scf calculations.<br>
<div class="im"><br>

<br>
</div>You should check the convergence of such mesh. The above 1 1 1 could be quite poor.<br>
