If I don't specify ecutrho in the input, what will be the default value for ecutrho for the ultrasoft pp. I know that for NC pp, ecutrho = 4*ecutwfc, but I do not know if the same value is used for US pp. On the other hand, if I specify ecutrho = 8*ecutwfc, then does the same value apply to the NC pp.<br><br>Thank you very much,<br><br>Vi <br>University of Houston <br><br><br></div>
