Also ecutrho should be atleast 10-12 times ecutwfc, you should check the convergence of the quantity of interest wrt ecutrho, ecutwfc & k-points.<br><br>Prasenjit.<br><br><div class="gmail_quote">2009/4/7 Dimpy Sharma <span dir="ltr"><<a href="mailto:dimpy.sharma@tyndall.ie">dimpy.sharma@tyndall.ie</a>></span><br>

<br>
I am not getting my output . My input file is given below. I have kept the kinetic energy cut of for the wavefunction (ecutwfc) as 35Ry. Can you please tell me.<br>
